Message RAM configuration data.
|
||||
Multiple M_CAN instances can share the same Message RAM
|
||||
and each element(e.g Rx FIFO or Tx Buffer and etc) number
|
||||
in Message RAM is also configurable, so this property is
|
||||
telling driver how the shared or private Message RAM are
|
||||
used by this M_CAN controller.
|
||||
|
||||
The format should be as follows:
|
||||
<offset sidf_elems xidf_elems rxf0_elems rxf1_elems rxb_elems txe_elems txb_elems>
|
||||
The 'offset' is an address offset of the Message RAM where
|
||||
the following elements start from. This is usually set to
|
||||
0x0 if you're using a private Message RAM. The remain cells
|
||||
are used to specify how many elements are used for each FIFO/Buffer.
|
||||
|
||||
M_CAN includes the following elements according to user manual:
|
||||
11-bit Filter 0-128 elements / 0-128 words
|
||||
29-bit Filter 0-64 elements / 0-128 words
|
||||
Rx FIFO 0 0-64 elements / 0-1152 words
|
||||
Rx FIFO 1 0-64 elements / 0-1152 words
|
||||
Rx Buffers 0-64 elements / 0-1152 words
|
||||
Tx Event FIFO 0-32 elements / 0-64 words
|
||||
Tx Buffers 0-32 elements / 0-576 words
|
||||
|
||||
Please refer to 2.4.1 Message RAM Configuration in Bosch
|
||||

Memory mapped Bosch CC770 and Intel AN82527 CAN controller
|
||||
|
||||
Note: The CC770 is a CAN controller from Bosch, which is 100%
|
||||
compatible with the old AN82527 from Intel, but with "bugs" being fixed.
|
||||
|
||||
Required properties:
|
||||
|
||||
- compatible : should be "bosch,cc770" for the CC770 and "intc,82527"
|
||||
for the AN82527.
|
||||
|
||||
- reg : should specify the chip select, address offset and size required
|
||||
to map the registers of the controller. The size is usually 0x80.
|
||||
|
||||
- interrupts : property with a value describing the interrupt source
|
||||
(number and sensitivity) required for the controller.
|
||||
|
||||
Optional properties:
|
||||
|
||||
- bosch,external-clock-frequency : frequency of the external oscillator
|
||||
clock in Hz. Note that the internal clock frequency used by the
|
||||
controller is half of that value. If not specified, a default
|
||||
value of 16000000 (16 MHz) is used.
|
||||
|
||||
- bosch,clock-out-frequency : slock frequency in Hz on the CLKOUT pin.
|
||||
If not specified or if the specified value is 0, the CLKOUT pin
|
||||
will be disabled.
|
||||
|
||||
- bosch,slew-rate : slew rate of the CLKOUT signal. If not specified,
|
||||
a resonable value will be calculated.
|
||||
|
||||
- bosch,disconnect-rx0-input : see data sheet.
|
||||
|
||||
- bosch,disconnect-rx1-input : see data sheet.
|
||||
|
||||
- bosch,disconnect-tx1-output : see data sheet.
|
||||
|
||||
- bosch,polarity-dominant : see data sheet.
|
||||
|
||||
- bosch,divide-memory-clock : see data sheet.
|
||||
|
||||
- bosch,iso-low-speed-mux : see data sheet.
|
||||
|
||||
For further information, please have a look to the CC770 or AN82527.
|
||||
|
||||
Examples:
|
||||
|
||||
can@3,100 {

Aeroflex Gaisler GRCAN and GRHCAN CAN controllers.
|
||||
|
||||
The GRCAN and CRHCAN CAN controllers are available in the GRLIB VHDL IP core
|
||||
library.
|
||||
|
||||
Note: These properties are built from the AMBA plug&play in a Leon SPARC system
|
||||
(the ordinary environment for GRCAN and GRHCAN). There are no dts files for
|
||||
sparc.
|
||||
|
||||
Required properties:
|
||||
|
||||
- name : Should be "GAISLER_GRCAN", "01_03d", "GAISLER_GRHCAN" or "01_034"
|
||||
|
||||
- reg : Address and length of the register set for the device
|
||||
|
||||
- freq : Frequency of the external oscillator clock in Hz (the frequency of
|
||||
the amba bus in the ordinary case)
|
||||
|
||||
- interrupts : Interrupt number for this device
|
||||
|
||||
Optional properties:
|
||||
|
||||
- systemid : If not present or if the value of the least significant 16 bits
|
||||
of this 32-bit property is smaller than GRCAN_TXBUG_SAFE_GRLIB_VERSION
|
||||
a bug workaround is activated.
|
||||
|
||||

- fsl,mscan-clock-source : a string describing the clock source. Valid values
|
||||
are: "ip" for ip bus clock
|
||||
"ref" for reference clock
|
||||
"sys" for system clock
|
||||
If this property is not present, an optimal CAN
|
||||
clock source and frequency based on the system
|
||||
clock will be selected. If this is not possible,
|
||||
the reference clock will be used.
|
||||
|
||||
- fsl,mscan-clock-divider: for the reference and system clock, an additional
|
||||
clock divider can be specified. By default, a
|
||||
value of 1 is used.
|
||||
|
||||
Note that the MPC5121 Rev. 1 processor is not supported.

Texas Instruments TCAN4x5x CAN Controller
|
||||
================================================
|
||||
|
||||
This file provides device node information for the TCAN4x5x interface contains.
|
||||
|
||||
Required properties:
|
||||
- compatible: "ti,tcan4x5x"
|
||||
- reg: 0
|
||||
- #address-cells: 1
|
||||
- #size-cells: 0
|
||||
- spi-max-frequency: Maximum frequency of the SPI bus the chip can
|
||||
operate at should be less than or equal to 18 MHz.
|
||||
- interrupt-parent: the phandle to the interrupt controller which provides
|
||||
the interrupt.
|
||||
- interrupts: interrupt specification for data-ready.
|
||||
|
||||
See Documentation/devicetree/bindings/net/can/bosch,m_can.yaml for additional
|
||||
required property details.
|
||||
|
||||
Optional properties:
|
||||
- reset-gpios: Hardwired output GPIO. If not defined then software
|
||||
reset.
|
||||
- device-state-gpios: Input GPIO that indicates if the device is in
|
||||
a sleep state or if the device is active.
|
||||
- device-wake-gpios: Wake up GPIO to wake up the TCAN device.
|
||||
|
||||
Example:
|
||||
tcan4x5x: tcan4x5x@0 {
|
||||
compatible = "ti,tcan4x5x";
|
||||
reg = <0>;
|
||||
#address-cells = <1>;
|
||||
#size-cells = <1>;
|
||||
spi-max-frequency = <10000000>;
|
||||
bosch,mram-cfg = <0x0 0 0 16 0 0 1 1>;
|
||||
interrupt-parent = <&gpio1>;
|
||||
interrupts = <14 IRQ_TYPE_LEVEL_LOW>;
|
||||
device-state-gpios = <&gpio3 21 GPIO_ACTIVE_HIGH>;
|
||||
device-wake-gpios = <&gpio1 15 GPIO_ACTIVE_HIGH>;
|
||||
reset-gpios = <&gpio1 27 GPIO_ACTIVE_HIGH>;

Texas Instruments High End CAN Controller (HECC)
|
||||
================================================
|
||||
|
||||
This file provides information, what the device node
|
||||
for the hecc interface contains.
|
||||
|
||||
Required properties:
|
||||
- compatible: "ti,am3517-hecc"
|
||||
- reg: addresses and lengths of the register spaces for 'hecc', 'hecc-ram'
|
||||
and 'mbx'
|
||||
- reg-names :"hecc", "hecc-ram", "mbx"
|
||||
- interrupts: interrupt mapping for the hecc interrupts sources
|
||||
- clocks: clock phandles (see clock bindings for details)
|
||||
|
||||
Optional properties:
|
||||
- ti,use-hecc1int: if provided configures HECC to produce all interrupts
|
||||
on HECC1INT interrupt line. By default HECC0INT interrupt
|
||||
line will be used.
|
||||
- xceiver-supply: regulator that powers the CAN transceiver
|
||||
|
||||
Example:
|
||||
|
||||
For am3517evm board:
|
||||
hecc: can@5c050000 {
|
||||
compatible = "ti,am3517-hecc";
|
||||
reg = <0x5c050000 0x80>,
|
||||
<0x5c053000 0x180>,
|
||||
<0x5c052000 0x200>;
|
||||
reg-names = "hecc", "hecc-ram", "mbx";
|
||||
interrupts = <24>;
|
||||
clocks = <&hecc_ck>;
|
||||
