|
||||
regulator node. The AS3722 is having 7 DCDC step-down regulators as
|
||||
sd[0-6], 10 LDOs as ldo[0-7], ldo[9-11]. The input supply of these
|
||||
regulators are provided through following properties:
|
||||
vsup-sd2-supply: Input supply for SD2.
|
||||
vsup-sd3-supply: Input supply for SD3.
|
||||
vsup-sd4-supply: Input supply for SD4.

|
||||
vin-ldo3-4-supply: Input supply for LDO3 and LDO4.
|
||||
vin-ldo9-10-supply: Input supply for LDO9 and LDO10.
|
||||
vin-ldo11-supply: Input supply for LDO11.
|
||||
|
||||
Optional nodes:
|
||||
--------------
|
||||
- regulators : Must contain a sub-node per regulator from the list below.
|
||||
Each sub-node should contain the constraints and initialization
|
||||
information for that regulator. See regulator.txt for a
|
||||
description of standard properties for these sub-nodes.
|
||||
Additional custom properties are listed below.
|
||||
sd[0-6], ldo[0-7], ldo[9-11].
|
||||
|
||||
Optional sub-node properties:
|
||||
----------------------------
|
||||
ams,ext-control: External control of the rail. The option of
|
||||
this properties will tell which external input is
|
||||
controlling this rail. Valid values are 0, 1, 2 ad 3.
|
||||
0: There is no external control of this rail.
|
||||
1: Rail is controlled by ENABLE1 input pin.
|
||||
2: Rail is controlled by ENABLE2 input pin.
|
||||
3: Rail is controlled by ENABLE3 input pin.
|
||||
ams,enable-tracking: Enable tracking with SD1, only supported
|
||||

Required properties:

- compatible: "lltc,ltc3589", "lltc,ltc3589-1" or "lltc,ltc3589-2"
|
||||
- reg: I2C slave address

Required child node:

|
||||
ldo1, ldo2, ldo3, and ldo4, specifying the initialization data as
|
||||
documented in Documentation/devicetree/bindings/regulator/regulator.txt.
|
||||
|
||||
Each regulator is defined using the standard binding for regulators. The
|
||||
nodes for sw1, sw2, sw3, bb-out, ldo1, and ldo2 additionally need to specify
|
||||
the resistor values of their external feedback voltage dividers:
|
||||
|
||||
Required properties (not on ldo3, ldo4):
|
||||
- lltc,fb-voltage-divider: An array of two integers containing the resistor
|
||||
values R1 and R2 of the feedback voltage divider in ohms.
|
||||
|
||||
Regulators sw1, sw2, sw3, and ldo2 can regulate the feedback reference from
|
||||
0.3625 V to 0.75 V in 12.5 mV steps. The output voltage thus ranges between
|
||||
0.3625 * (1 + R1/R2) V and 0.75 * (1 + R1/R2) V. Regulators bb-out and ldo1
|
||||
have a fixed 0.8 V reference and thus output 0.8 * (1 + R1/R2) V. The ldo3
|
||||
regulator is fixed to 1.8 V on LTC3589 and to 2.8 V on LTC3589-1,2. The ldo4
|
||||
regulator can output between 1.8 V and 3.3 V on LTC3589 and between 1.2 V
|
||||
and 3.2 V on LTC3589-1,2 in four steps. The ldo1 standby regulator can not

The MAX20086-MAX20089 are dual/quad camera power protectors, designed to
|
||||
deliver power over coax for radar and camera modules. They support
|
||||
software-configurable output switching and monitoring. The output voltage and
|
||||
current limit are fixed by the hardware design.

This is a part of device tree bindings for Maxim MAX77802 Power Management
|

Integrated Circuit (PMIC).
|
||||
|
||||
The Maxim MAX77686 provides 10 high-efficiency Buck and 32 Low-DropOut (LDO)
|
||||
regulators.
|
||||
|
||||
See also Documentation/devicetree/bindings/mfd/maxim,max77802.yaml for
|
||||
additional information and example.
|
||||
|
||||
Certain regulators support "regulator-initial-mode" and "regulator-mode".
|
||||
The valid modes list is defined in the dt-bindings/regulator/maxim,max77802.h
|
||||
and their meaning is::
|
||||
1 - Normal regulator voltage output mode.
|
||||
3 - Low Power which reduces the quiescent current down to only 1uA
|
||||
|
||||
The standard "regulator-mode" property can only be used for regulators that
|
||||
support changing their mode to Low Power Mode during suspend. These
|
||||
regulators are:: bucks 2-4 and LDOs 1-35. Also, it only takes effect if the
|
||||
regulator has been enabled for the given suspend state using
|
||||
"regulator-on-in-suspend" and has not been disabled for that state using
|
||||
"regulator-off-in-suspend".

MCP16502 PMIC
|
||||
|
||||
Required properties:
|
||||
- compatible: "microchip,mcp16502"
|
||||
- reg: I2C slave address
|
||||
- lpm-gpios: GPIO for LPM pin. Note that this GPIO *must* remain high during
|
||||
suspend-to-ram, keeping the PMIC into HIBERNATE mode; this
|
||||
property is optional;
|
||||
- regulators: A node that houses a sub-node for each regulator within
|
||||
the device. Each sub-node is identified using the node's
|
||||
name. The content of each sub-node is defined by the
|
||||
standard binding for regulators; see regulator.txt.
|
||||
|
||||
Regulators of MCP16502 PMIC:
|
||||
1) VDD_IO - Buck (1.2 - 3.7 V)
|
||||
2) VDD_DDR - Buck (0.6 - 1.85 V)
|
||||
3) VDD_CORE - Buck (0.6 - 1.85 V)
|
||||
4) VDD_OTHER - BUCK (0.6 - 1.85 V)
|
||||
5) LDO1 - LDO (1.2 - 3.7 V)
|
||||
6) LDO2 - LDO (1.2 - 3.7 V)
|
||||
|
||||
Regulator modes:
|
||||
2 - FPWM: higher precision, higher consumption
|
||||
4 - AutoPFM: lower precision, lower consumption
|
||||
|
||||
Each regulator is defined using the standard binding for regulators.

The MT6331 PMIC provides 6 BUCK and 21 LDO (Low Dropout) regulators
|
||||
and nodes are named according to the regulator type:
|
||||
buck-<name> and ldo-<name>.
|
||||
MT6331 regulators node should be sub node of the MT6397 MFD node.

Mediatek MT6323 Regulator
|
||||
|
||||
All voltage regulators are defined as subnodes of the regulators node. A list
|
||||
of regulators provided by this controller are defined as subnodes of the
|
||||
PMIC's node. Each regulator is named according to its regulator type,
|
||||
buck_<name> and ldo_<name>. The definition for each of these nodes is defined
|
||||
using the standard binding for regulators at
|
||||
Documentation/devicetree/bindings/regulator/regulator.txt.
|
||||
|
||||
The valid names for regulators are::
|
||||
BUCK:
|
||||
buck_vproc, buck_vsys, buck_vpa
|
||||
LDO:
|
||||
ldo_vtcxo, ldo_vcn28, ldo_vcn33_bt, ldo_vcn33_wifi, ldo_va, ldo_vcama,
|
||||
ldo_vio28, ldo_vusb, ldo_vmc, ldo_vmch, ldo_vemc3v3, ldo_vgp1, ldo_vgp2,

MediaTek MT6380 Regulator
|
||||
|
||||
All voltage regulators provided by the MT6380 PMIC are described as the
|
||||
subnodes of the MT6380 regulators node. Each regulator is named according
|
||||
to its regulator type, buck-<name> and ldo-<name>. The definition for each
|
||||
of these nodes is defined using the standard binding for regulators at
|
||||
Documentation/devicetree/bindings/regulator/regulator.txt.
|
||||
|
||||
The valid names for regulators are:
|
||||
BUCK:
|
||||
buck-core1, buck-vcore, buck-vrf
|
||||
LDO:
|
||||
ldo-vm ,ldo-va , ldo-vphy, ldo-vddr, ldo-vt

- mt6397regulator: List of regulators provided by this controller. It is named
|
||||
according to its regulator type, buck_<name> and ldo_<name>.
|
||||
The definition for each of these nodes is defined using the standard binding
|
||||
for regulators at Documentation/devicetree/bindings/regulator/regulator.txt.
|
||||
|
||||
The valid names for regulators are::
|
||||
BUCK:
|
||||
buck_vpca15, buck_vpca7, buck_vsramca15, buck_vsramca7, buck_vcore, buck_vgpu,
|
||||
buck_vdrm, buck_vio18
|
||||
LDO:
|

ldo_vtcxo, ldo_va28, ldo_vcama, ldo_vio28, ldo_vusb, ldo_vmc, ldo_vmch,
|
||||
ldo_vemc3v3, ldo_vgp1, ldo_vgp2, ldo_vgp3, ldo_vgp4, ldo_vgp5, ldo_vgp6,
|
||||
ldo_vibr

NVIDIA Tegra Regulators Coupling
|
||||
================================
|
||||
|
||||
NVIDIA Tegra SoC's have a mandatory voltage-coupling between regulators.
|
||||
Thus on Tegra20 there are 3 coupled regulators and on NVIDIA Tegra30
|
||||
there are 2.
|
||||
|
||||
Tegra20 voltage coupling
|
||||
------------------------
|
||||
|
||||
On Tegra20 SoC's there are 3 coupled regulators: CORE, RTC and CPU.
|
||||
The CORE and RTC voltages shall be in a range of 170mV from each other
|
||||
and they both shall be higher than the CPU voltage by at least 120mV.
|
||||
|
||||
Tegra30 voltage coupling
|
||||
------------------------
|
||||
|
||||
On Tegra30 SoC's there are 2 coupled regulators: CORE and CPU. The CORE
|
||||
and CPU voltages shall be in a range of 300mV from each other and CORE
|
||||
voltage shall be higher than the CPU by N mV, where N depends on the CPU
|
||||
voltage.
|
||||
|
||||
Required properties:
|
||||
- nvidia,tegra-core-regulator: Boolean property that designates regulator
|
||||
as the "Core domain" voltage regulator.
|
||||
- nvidia,tegra-rtc-regulator: Boolean property that designates regulator
|
||||
as the "RTC domain" voltage regulator.
|
||||
- nvidia,tegra-cpu-regulator: Boolean property that designates regulator
|
||||
as the "CPU domain" voltage regulator.
|
||||
|
||||
Example:
|
||||
|
||||
pmic {
|
||||
regulators {
|
||||
core_vdd_reg: core {
|
||||
regulator-name = "vdd_core";

The tps659038 for the AM57x class have OTP spins that
|
||||
have different part numbers but the same functionality. There
|
||||
is not a need to add the OTP spins to the palmas driver. The
|
||||
spin devices should use the tps659038 as it's compatible value.
|
||||
This is the list of those devices:
|
||||
tps659037
|
||||
|
||||
Required properties:
|
||||
- compatible : Should be from the list
|
||||

ti,tps659038-pmic
|
||||
and also the generic series names
|
||||
ti,palmas-pmic
|
||||
- interrupts : The interrupt number and the type which can be looked up here:
|
||||
arch/arm/boot/dts/include/dt-bindings/interrupt-controller/irq.h
|
||||
- interrupts-name: The names of the individual interrupts.
|
||||
|
||||
Optional properties:
|
||||
- ti,ldo6-vibrator : ldo6 is in vibrator mode
|
||||
|
||||
Optional nodes:
|
||||
- regulators : Must contain a sub-node per regulator from the list below.
|
||||
Each sub-node should contain the constraints and initialization
|
||||
information for that regulator. See regulator.txt for a
|
||||
description of standard properties for these sub-nodes.
|
||||
Additional custom properties are listed below.
|
||||
|
||||
For ti,palmas-pmic - smps12, smps123, smps3 depending on OTP,
|
||||
smps45, smps457, smps7 depending on variant, smps6, smps[8-9],
|
||||
smps10_out2, smps10_out1, ldo[1-9], ldoln, ldousb.
|
||||
|
||||
Optional sub-node properties:
|
||||
ti,warm-reset - maintain voltage during warm reset(boolean)
|
||||
ti,roof-floor - This takes as optional argument on platform supporting
|
||||
the rail from desired external control. If there is no argument then
|
||||
it will be assume that it is controlled by NSLEEP pin.
|
||||
The valid value for external pins are:
|
||||
ENABLE1 then 1,
|
||||
ENABLE2 then 2 or
|
||||
NSLEEP then 3.
|
||||
ti,mode-sleep - mode to adopt in pmic sleep 0 - off, 1 - auto,
|
||||
2 - eco, 3 - forced pwm
|
||||
ti,smps-range - OTP has the wrong range set for the hardware so override
|
||||
0 - low range, 1 - high range.
|
||||
|
||||
- ti,system-power-controller: Telling whether or not this pmic is controlling
|
||||
the system power.

Boolean, if present disable all unused switch regulators to save power

consumption. Attention, ensure that all important regulators

(e.g. DDR ref, DDR supply) has set the "regulator-always-on" property.
|

If not present, the switched regulators are always on and can't be
|

disabled. This binding is a workaround to keep backward compatibility
|

with old dtb's which rely on the fact that the switched regulators are

always on and don't mark them explicit as "regulator-always-on".

Currently supports 2 modes of operation:
|
||||
|
||||
Voltage Table:
|
||||
When in this mode, a voltage table (See below) of predefined voltage <=>
|
||||
duty-cycle values must be provided via DT. Limitations are that the
|
||||
regulator can only operate at the voltages supplied in the table.
|
||||
Intermediary duty-cycle values which would normally allow finer grained
|
||||
voltage selection are ignored and rendered useless. Although more control
|
||||
is given to the user if the assumptions made in continuous-voltage mode do
|
||||
not reign true.
|
||||
|
||||
Continuous Voltage:
|
||||
This mode uses the regulator's maximum and minimum supplied voltages
|
||||
specified in the regulator-{min,max}-microvolt properties to calculate
|
||||
appropriate duty-cycle values. This allows for a much more fine grained
|
||||
solution when compared with voltage-table mode above. This solution does
|
||||
make an assumption that a %50 duty-cycle value will cause the regulator
|
||||
voltage to run at half way between the supplied max_uV and min_uV values.
|
||||
|
||||
If voltage-table is provided, then the device will be used in Voltage Table
|
||||
Mode. If no voltage-table is provided, then the device will be used in
|
||||
Continuous Voltage Mode.

description: |
|
||||
rpmh-regulator devices support PMIC regulator management via the Voltage
|
||||
Regulator Manager (VRM) and Oscillator Buffer (XOB) RPMh accelerators.
|
||||
The APPS processor communicates with these hardware blocks via a
|
||||
Resource State Coordinator (RSC) using command packets. The VRM allows
|
||||
changing three parameters for a given regulator, enable state, output
|
||||
voltage, and operating mode. The XOB allows changing only a single
|
||||
parameter for a given regulator, its enable state. Despite its name,
|
||||
the XOB is capable of controlling the enable state of any PMIC peripheral.
|
||||
It is used for clock buffers, low-voltage switches, and LDO/SMPS regulators
|
||||
which have a fixed voltage and mode.
|
||||
|
||||
=======================
|
||||
Required Node Structure
|
||||
=======================
|
||||
|
||||
RPMh regulators must be described in two levels of device nodes. The first
|
||||
level describes the PMIC containing the regulators and must reside within an
|
||||
RPMh device node. The second level describes each regulator within the PMIC
|
||||
which is to be used on the board. Each of these regulators maps to a single
|
||||
RPMh resource.
|
||||
|
||||
The names used for regulator nodes must match those supported by a given
|
||||
PMIC. Supported regulator node names are
|
||||

title: QCOM SMD RPM REGULATOR
|
||||
|
||||
description:
|
||||
The Qualcomm RPM over SMD regulator is modelled as a subdevice of the RPM.
|
||||
Because SMD is used as the communication transport mechanism, the RPM
|
||||
resides as a subnode of the SMD. As such, the SMD-RPM regulator requires
|
||||
that the SMD and RPM nodes be present.
|
||||
|
||||
Please refer to Documentation/devicetree/bindings/soc/qcom/qcom,smd.yaml for
|
||||
information pertaining to the SMD node.
|
||||
|
||||
Please refer to Documentation/devicetree/bindings/soc/qcom/qcom,smd-rpm.yaml
|
||||
for information regarding the RPM node.
|
||||
|
||||
The regulator node houses sub-nodes for each regulator within the device.
|
||||
Each sub-node is identified using the node's name, with valid values listed
|
||||
for each of the pmics below.

Regulator DT binding for MAX77620 Power management IC from Maxim Semiconductor.
|
||||
|
||||
Device has multiple DCDC(sd[0-3] and LDOs(ldo[0-8]). The input supply
|
||||
of these regulators are defined under parent device node.
|
||||
Details of regulator properties are defined as child node under
|
||||
sub-node "regulators" which is child node of device node.
|
||||
|
||||
Please refer file <Documentation/devicetree/bindings/regulator/regulator.txt>
|
||||
for common regulator bindings used by client.
|
||||
|
||||
Following are properties of parent node related to regulators.
|
||||
|
||||
Optional properties:
|
||||
-------------------
|
||||
The input supply of regulators are the optional properties on the
|
||||
parent device node. The input supply of these regulators are provided
|
||||
through following properties:
|
||||
in-sd0-supply: Input supply for SD0, INA-SD0 or INB-SD0 pins.
|
||||
in-sd1-supply: Input supply for SD1.
|
||||
in-sd2-supply: Input supply for SD2.
|
||||
in-sd3-supply: Input supply for SD3.
|
||||
in-ldo0-1-supply: Input supply for LDO0 and LDO1.
|
||||
in-ldo2-supply: Input supply for LDO2.
|
||||
in-ldo3-5-supply: Input supply for LDO3 and LDO5
|
||||
in-ldo4-6-supply: Input supply for LDO4 and LDO6.
|
||||
in-ldo7-8-supply: Input supply for LDO7 and LDO8.
|
||||
|
||||
Optional sub nodes for regulators under "regulators" subnode:
|
||||
------------------------------------------------------------
|
||||
The subnodes name is the name of regulator and it must be one of:
|
||||
sd[0-3], ldo[0-8]
|
||||
|
||||
Each sub-node should contain the constraints and initialization
|
||||
information for that regulator. The definition for each of these
|
||||
nodes is defined using the standard binding for regulators found at
|
||||
<Documentation/devicetree/bindings/regulator/regulator.txt>.
|
||||
|
||||
Theres are also additional properties for SD/LDOs. These additional properties
|
||||
are required to configure FPS configuration parameters for SDs and LDOs.
|
||||
Please refer <devicetree/bindings/mfd/max77620.txt> for more detail of Flexible
|
||||
Power Sequence (FPS).
|
||||
Following are additional properties:
|
||||
|
||||
- maxim,active-fps-source: FPS source for the regulators to get
|
||||
enabled/disabled when system is in
|
||||
active state. Valid values are:
|
||||
- MAX77620_FPS_SRC_0,
|
||||
FPS source is FPS0.
|
||||
- MAX77620_FPS_SRC_1,
|
||||
FPS source is FPS1
|
||||
- MAX77620_FPS_SRC_2 and
|
||||
FPS source is FPS2
|
||||
- MAX77620_FPS_SRC_NONE.
|
||||
Regulator is not controlled
|
||||
by FPS events and it gets
|
||||
enabled/disabled by register
|
||||
access.
|
||||
Absence of this property will leave
|
||||
the FPS configuration register for that
|
||||
regulator to default configuration.
|
||||
|
||||
- maxim,active-fps-power-up-slot: Sequencing event slot number on which
|
||||
the regulator get enabled when
|
||||
master FPS input event set to HIGH.
|
||||
Valid values are 0 to 7.
|
||||
This is applicable if FPS source is
|
||||
selected as FPS0, FPS1 or FPS2.
|
||||
|
||||
- maxim,active-fps-power-down-slot: Sequencing event slot number on which
|
||||
the regulator get disabled when master
|
||||
FPS input event set to LOW.
|
||||
Valid values are 0 to 7.
|
||||
This is applicable if FPS source is
|
||||
selected as FPS0, FPS1 or FPS2.
|
||||
|
||||
- maxim,suspend-fps-source: This is same as property
|
||||
"maxim,active-fps-source" but value
|
||||
get configured when system enters in
|
||||
to suspend state.
|
||||
|
||||
- maxim,suspend-fps-power-up-slot: This is same as property
|
||||
"maxim,active-fps-power-up-slot" but
|
||||
this value get configured into FPS
|
||||
configuration register when system
|
||||
enters into suspend.
|
||||
This is applicable if suspend state
|
||||
FPS source is selected as FPS0, FPS1 or
|
||||
|
||||
- maxim,suspend-fps-power-down-slot: This is same as property
|
||||
"maxim,active-fps-power-down-slot" but
|
||||
this value get configured into FPS
|
||||
configuration register when system
|
||||
enters into suspend.
|
||||
This is applicable if suspend state
|
||||
FPS source is selected as FPS0, FPS1 or
|
||||
FPS2.
|
||||
- maxim,ramp-rate-setting: integer, ramp rate(uV/us) setting to be
|
||||
configured to the device.
|
||||
The platform may have different ramp
|
||||
rate than advertised ramp rate if it has
|
||||
design variation from Maxim's
|
||||
recommended. On this case, platform
|
||||
specific ramp rate is used for ramp time
|
||||
calculation and this property is used
|
||||
for device register configurations.
|
||||
The measured ramp rate of platform is
|
||||
provided by the regulator-ramp-delay
|
||||
as described in <devicetree/bindings/
|
||||
regulator/regulator.txt>.
|
||||
Maxim Max77620 supports following ramp
|
||||
delay:
|
||||
SD: 13.75mV/us, 27.5mV/us, 55mV/us
|
||||
LDOs: 5mV/us, 100mV/us
|
||||
|
||||
Note: If the measured ramp delay is same as advertised ramp delay then it is not
|
||||
required to provide the ramp delay with property "maxim,ramp-rate-setting". The
|
||||
ramp rate can be provided by the regulator-ramp-delay which will be used for
|
||||
ramp time calculation for voltage change as well as for device configuration.

description: |
|

RT4831 is a multifunctional device that can provide power to the LCD display
|
||||
and LCD backlight.
|
||||
|
||||
For Display Bias Voltage DSVP and DSVN, the output range is about 4V to 6.5V.
|
||||
It is sufficient to meet the current LCD power requirement.
|
||||
|
||||
DSVLCM is a boost regulator in IC internal as DSVP and DSVN input power.
|
||||
Its voltage should be configured above 0.15V to 0.2V gap larger than the
|
||||
voltage needed for DSVP and DSVN. Too much voltage gap could improve the
|
||||
voltage drop from the heavy loading scenario. But it also make the power
|
||||
efficiency worse. It's a trade-off.

The mute function uses 'mutein', 'muteout', and 'vdet' pins as the control

signal. When enabled, The normal behavior is to bypass the 'mutein' signal
|
||||
'muteout'. But if the power source removal is detected from 'vdet',
|
||||
whatever the 'mutein' signal is, it will pull down the 'muteout' to force
|
||||
speakers mute. this function is commonly used to prevent the speaker pop
|

noise during AC power turned off in the modern TV system design.

(Enable/Fail), Enable pin to turn chip on, and Fail pin as fault indication.
|
||||
There're still four pins for camera control, two inputs (strobe and vsync),
|

the others for outputs (fsin1 and fsin2). Strobe input to start the current
|
||||
supply, vsync input from IR camera, and fsin1/fsin2 output for the optional.

List of regulators provided by this controller. BD71837 regulators node

should be sub node of the BD71837 MFD node. See BD71837 MFD bindings at
|
||||
Documentation/devicetree/bindings/mfd/rohm,bd71837-pmic.yaml
|
||||
Regulator nodes should be named to BUCK_<number> and LDO_<number>. The
|
||||
definition for each of these nodes is defined using the standard
|
||||
binding for regulators at
|
||||
Documentation/devicetree/bindings/regulator/regulator.txt.
|
||||
Note that if BD71837 starts at RUN state you probably want to use
|
||||
regulator-boot-on at least for BUCK6 and BUCK7 so that those are not
|
||||
disabled by driver at startup. LDO5 and LDO6 are supplied by those and
|
||||
if they are disabled at startup the voltage monitoring for LDO5/LDO6 will
|
||||
cause PMIC to reset.

should be sub node of the BD71847 MFD node. See BD71847 MFD bindings at
|

Documentation/devicetree/bindings/mfd/rohm,bd71847-pmic.yaml
|

Regulator nodes should be named to BUCK_<number> and LDO_<number>. The
|

definition for each of these nodes is defined using the standard
|

binding for regulators at
|

Documentation/devicetree/bindings/regulator/regulator.txt.

Note that if BD71847 starts at RUN state you probably want to use
|

regulator-boot-on at least for BUCK5. LDO6 is supplied by it and it must
|
||||
not be disabled by driver at startup. If BUCK5 is disabled at startup the
|
||||
voltage monitoring for LDO5/LDO6 can cause PMIC to reset.

- compatible : Should be "dlg,slg51000" for SLG51000
|
||||
- reg : Specifies the I2C slave address.
|
||||
- xxx-supply: Input voltage supply regulator for ldo3 to ldo7.
|
||||
These entries are required if regulators are enabled for a device.
|
||||
An absence of these properties can cause the regulator registration to fail.
|
||||
If some of input supply is powered through battery or always-on supply then
|
||||
also it is required to have these parameters with proper node handle of always
|
||||
on power supply.
|
||||
vin3-supply: Input supply for ldo3
|
||||
vin4-supply: Input supply for ldo4
|
||||
vin5-supply: Input supply for ldo5
|
||||
vin6-supply: Input supply for ldo6
|
||||
vin7-supply: Input supply for ldo7
|
||||
|
||||
Optional properties:
|
||||
- interrupt-parent : Specifies the reference to the interrupt controller.
|
||||
- interrupts : IRQ line information.
|
||||
- dlg,cs-gpios : Specify a valid GPIO for chip select
|
||||
|
||||
Sub-nodes:
|
||||
- regulators : This node defines the settings for the regulators.
|
||||
The content of the sub-node is defined by the standard binding
|
||||
for regulators; see regulator.txt.
|
||||
|
||||
The SLG51000 regulators are bound using their names listed below:

title: Socionext UniPhier regulator controller
|
||||
|
||||
description: |
|
||||
This regulator controls VBUS and belongs to USB3 glue layer. Before using
|
||||
the regulator, it is necessary to control the clocks and resets to enable
|
||||
this layer. These clocks and resets should be described in each property.
