+Pistachio Reset Controller
+=============================================================================
+
+This binding describes a reset controller device that is used to enable and
+disable individual IP blocks within the Pistachio SoC using "soft reset"
+control bits found in the Pistachio SoC top level registers.
+
+The actual action taken when soft reset is asserted is hardware dependent.
+However, when asserted it may not be possible to access the hardware's
+registers, and following an assert/deassert sequence the hardware's previous
+state may no longer be valid.
+
+Please refer to Documentation/devicetree/bindings/reset/reset.txt
+for common reset controller binding usage.
+
+Required properties:
+
+- compatible: Contains "img,pistachio-reset"
+
+- #reset-cells: Contains 1
+
+Example:
+
+	cr_periph: clk@18148000 {
+		compatible = "img,pistachio-cr-periph", "syscon", "simple-mfd";
+		reg = <0x18148000 0x1000>;
+		clocks = <&clk_periph PERIPH_CLK_SYS>;
+		clock-names = "sys";
+		#clock-cells = <1>;
+
+		pistachio_reset: reset-controller {
+			compatible = "img,pistachio-reset";
+			#reset-cells = <1>;
+		};
+	};
+
+Specifying reset control of devices
+=======================================
+
+Device nodes should specify the reset channel required in their "resets"
+property, containing a phandle to the pistachio reset device node and an
+index specifying which reset to use, as described in
+Documentation/devicetree/bindings/reset/reset.txt.
+
+Example:
+
+	spdif_out: spdif-out@18100d00 {
+		...
+		resets = <&pistachio_reset PISTACHIO_RESET_SPDIF_OUT>;
+		reset-names = "rst";
+		...
+	};
+
+Macro definitions for the supported resets can be found in:
+include/dt-bindings/reset/pistachio-resets.h

+= Reset Signal Device Tree Bindings =
+
+This binding is intended to represent the hardware reset signals present
+internally in most IC (SoC, FPGA, ...) designs. Reset signals for whole
+standalone chips are most likely better represented as GPIOs, although there
+are likely to be exceptions to this rule.
+
+Hardware blocks typically receive a reset signal. This signal is generated by
+a reset provider (e.g. power management or clock module) and received by a
+reset consumer (the module being reset, or a module managing when a sub-
+ordinate module is reset). This binding exists to represent the provider and
+consumer, and provide a way to couple the two together.
+
+A reset signal is represented by the phandle of the provider, plus a reset
+specifier - a list of DT cells that represents the reset signal within the
+provider. The length (number of cells) and semantics of the reset specifier
+are dictated by the binding of the reset provider, although common schemes
+are described below.
+
+A word on where to place reset signal consumers in device tree: It is possible
+in hardware for a reset signal to affect multiple logically separate HW blocks
+at once. In this case, it would be unwise to represent this reset signal in
+the DT node of each affected HW block, since if activated, an unrelated block
+may be reset. Instead, reset signals should be represented in the DT node
+where it makes most sense to control it; this may be a bus node if all
+children of the bus are affected by the reset signal, or an individual HW
+block node for dedicated reset signals. The intent of this binding is to give
+appropriate software access to the reset signals in order to manage the HW,
+rather than to slavishly enumerate the reset signal that affects each HW
+block.
+
+= Reset providers =
+
+Required properties:
+#reset-cells:	Number of cells in a reset specifier; Typically 0 for nodes
+		with a single reset output and 1 for nodes with multiple
+		reset outputs.
+
+For example:
+
+	rst: reset-controller {
+		#reset-cells = <1>;
+	};
+
+= Reset consumers =
+
+Required properties:
+resets:		List of phandle and reset specifier pairs, one pair
+		for each reset signal that affects the device, or that the
+		device manages. Note: if the reset provider specifies '0' for
+		#reset-cells, then only the phandle portion of the pair will
+		appear.
+
+Optional properties:
+reset-names:	List of reset signal name strings sorted in the same order as
+		the resets property. Consumers drivers will use reset-names to
+		match reset signal names with reset specifiers.
+
+For example:
+
+	device {
+		resets = <&rst 20>;
+		reset-names = "reset";
+	};
+
+This represents a device with a single reset signal named "reset".
+
+	bus {
+		resets = <&rst 10> <&rst 11> <&rst 12> <&rst 11>;
+		reset-names = "i2s1", "i2s2", "dma", "mixer";
+	};
+
+This represents a bus that controls the reset signal of each of four sub-
+ordinate devices. Consider for example a bus that fails to operate unless no
+child device has reset asserted.

+STMicroelectronics STi family Sysconfig Peripheral SoftReset Controller
+=============================================================================
+
+This binding describes a reset controller device that is used to enable and
+disable on-chip peripheral controllers such as USB and SATA, using
+"softreset" control bits found in the STi family SoC system configuration
+registers.
+
+The actual action taken when softreset is asserted is hardware dependent.
+However, when asserted it may not be possible to access the hardware's
+registers and after an assert/deassert sequence the hardware's previous state
+may no longer be valid.
+
+Please refer to reset.txt in this directory for common reset
+controller binding usage.
+
+Required properties:
+- compatible: Should be "st,stih407-softreset";
+- #reset-cells: 1, see below
+
+example:
+
+	softreset: softreset-controller {
+		#reset-cells = <1>;
+		compatible = "st,stih407-softreset";
+	};
+
+
+Specifying softreset control of devices
+=======================================
+
+Device nodes should specify the reset channel required in their "resets"
+property, containing a phandle to the softreset device node and an
+index specifying which channel to use, as described in reset.txt
+
+example:
+
+	ethernet0{
+		resets			= <&softreset STIH415_ETH0_SOFTRESET>;
+	};
+
+Macro definitions for the supported reset channels can be found in:

+TI SysCon Reset Controller
+=======================
+
+Almost all SoCs have hardware modules that require reset control in addition
+to clock and power control for their functionality. The reset control is
+typically provided by means of memory-mapped I/O registers. These registers are
+sometimes a part of a larger register space region implementing various
+functionalities. This register range is best represented as a syscon node to
+allow multiple entities to access their relevant registers in the common
+register space.
+
+A SysCon Reset Controller node defines a device that uses a syscon node
+and provides reset management functionality for various hardware modules
+present on the SoC.
+
+SysCon Reset Controller Node
+============================
+Each of the reset provider/controller nodes should be a child of a syscon
+node and have the following properties.
+
+Required properties:
+--------------------
+ - compatible		: Should be,
+			    "ti,k2e-pscrst"
+			    "ti,k2l-pscrst"
+			    "ti,k2hk-pscrst"
+			    "ti,syscon-reset"
+ - #reset-cells		: Should be 1. Please see the reset consumer node below
+			  for usage details
+ - ti,reset-bits	: Contains the reset control register information
+			  Should contain 7 cells for each reset exposed to
+			  consumers, defined as:
+			    Cell #1 : offset of the reset assert control
+			              register from the syscon register base
+			    Cell #2 : bit position of the reset in the reset
+			              assert control register
+			    Cell #3 : offset of the reset deassert control
+			              register from the syscon register base
+			    Cell #4 : bit position of the reset in the reset
+			              deassert control register
+			    Cell #5 : offset of the reset status register
+			              from the syscon register base
+			    Cell #6 : bit position of the reset in the
+			              reset status register
+			    Cell #7 : Flags used to control reset behavior,
+			              availible flags defined in the DT include
+			              file <dt-bindings/reset/ti-syscon.h>
+
+SysCon Reset Consumer Nodes
+===========================
+Each of the reset consumer nodes should have the following properties,
+in addition to their own properties.
+
+Required properties:
+--------------------
+ - resets	: A phandle to the reset controller node and an index number
+		  to a reset specifier as defined above.
+
+Please also refer to Documentation/devicetree/bindings/reset/reset.txt for
+common reset controller usage by consumers.
+
+Example:
+--------
+The following example demonstrates a syscon node, the reset controller node
+using the syscon node, and a consumer (a DSP device) on the TI Keystone 2
+66AK2E SoC.
+
+/ {
+	soc {
+		psc: power-sleep-controller@2350000 {
