From: Lina Iyer <ilina@codeaurora.org>

Add device binding documentation for Qualcomm Technology Inc's RPMH RSC
driver. The driver is used for communicating resource state requests for
shared resources.

+RPMH RSC:
+------------
+
+Resource Power Manager Hardened (RPMH) is the mechanism for communicating with
+the hardened resource accelerators on Qualcomm SoCs. Requests to the resources
+can be written to the Trigger Command Set (TCS)  registers and using a (addr,
+val) pair and triggered. Messages in the TCS are then sent in sequence over an
+internal bus.
+
+The hardware block (Direct Resource Voter or DRV) is a part of the h/w entity
+(Resource State Coordinator a.k.a RSC) that can handle multiple sleep and
+active/wake resource requests. Multiple such DRVs can exist in a SoC and can
+be written to from Linux. The structure of each DRV follows the same template
+with a few variations that are captured by the properties here.
+
+A TCS may be triggered from Linux or triggered by the F/W after all the CPUs
+have powered off to facilitate idle power saving. TCS could be classified as -
+
+	ACTIVE  /* Triggered by Linux */
+	SLEEP   /* Triggered by F/W */
+	WAKE    /* Triggered by F/W */
+	CONTROL /* Triggered by F/W */
+
+The order in which they are described in the DT, should match the hardware
+configuration.
+
+Requests can be made for the state of a resource, when the subsystem is active
+or idle. When all subsystems like Modem, GPU, CPU are idle, the resource state
+will be an aggregate of the sleep votes from each of those subsystems. Clients
+may request a sleep value for their shared resources in addition to the active
+mode requests.
+
+Properties:
+
+- compatible:
+	Usage: required
+	Value type: <string>
+	Definition: Should be "qcom,rpmh-rsc".
+
+- reg:
+	Usage: required
+	Value type: <prop-encoded-array>
+	Definition: The first register specifies the base address of the
+		    DRV(s). The number of DRVs in the dependent on the RSC.
+	            The tcs-offset specifies the start address of the
+	            TCS in the DRVs.
+
+- reg-names:
+	Usage: required
+	Value type: <string>
+	Definition: Maps the register specified in the reg property. Must be
+	            "drv-0", "drv-1", "drv-2" etc and "tcs-offset". The
+
+- interrupts:
+	Usage: required
+	Value type: <prop-encoded-interrupt>
+	Definition: The interrupt that trips when a message complete/response
+	           is received for this DRV from the accelerators.
+
+- qcom,drv-id:
+	Usage: required
+	Value type: <u32>
+	Definition: The id of the DRV in the RSC block that will be used by
+		    this controller.
+
+- qcom,tcs-config:
+	Usage: required
+	Value type: <prop-encoded-array>
+	Definition: The tuple defining the configuration of TCS.
+	            Must have 2 cells which describe each TCS type.
+	            <type number_of_tcs>.
+	            The order of the TCS must match the hardware
+	            configuration.
+	- Cell #1 (TCS Type): TCS types to be specified -
+	            ACTIVE_TCS
+	            SLEEP_TCS
+	            WAKE_TCS
+	            CONTROL_TCS
+	- Cell #2 (Number of TCS): <u32>
+
+- label:
+	Usage: optional
+	Value type: <string>
+	Definition: Name for the RSC. The name would be used in trace logs.
+
+Drivers that want to use the RSC to communicate with RPMH must specify their
+bindings as child nodes of the RSC controllers they wish to communicate with.
+
+Example 1:
+
+For a TCS whose RSC base address is is 0x179C0000 and is at a DRV id of 2, the
+register offsets for DRV2 start at 0D00, the register calculations are like
+this -
+DRV0: 0x179C0000
+DRV2: 0x179C0000 + 0x10000 = 0x179D0000
+DRV2: 0x179C0000 + 0x10000 * 2 = 0x179E0000
+TCS-OFFSET: 0xD00
+
+	apps_rsc: rsc@179c0000 {
+		label = "apps_rsc";
+		compatible = "qcom,rpmh-rsc";
+		reg = <0x179c0000 0x10000>,
+		      <0x179d0000 0x10000>,
+		      <0x179e0000 0x10000>;
+		reg-names = "drv-0", "drv-1", "drv-2";
+		interrupts = <GIC_SPI 3 IRQ_TYPE_LEVEL_HIGH>,
+			     <GIC_SPI 4 IRQ_TYPE_LEVEL_HIGH>,
+			     <GIC_SPI 5 IRQ_TYPE_LEVEL_HIGH>;
+		qcom,tcs-offset = <0xd00>;
+		qcom,drv-id = <2>;
+		qcom,tcs-config = <ACTIVE_TCS  2>,
+				  <SLEEP_TCS   3>,
+				  <WAKE_TCS    3>,
+				  <CONTROL_TCS 1>;
+	};
+
+Example 2:
+
+For a TCS whose RSC base address is 0xAF20000 and is at DRV id of 0, the
+register offsets for DRV0 start at 01C00, the register calculations are like
+this -
+DRV0: 0xAF20000
+TCS-OFFSET: 0x1C00
+
+	disp_rsc: rsc@af20000 {
+		label = "disp_rsc";
+		compatible = "qcom,rpmh-rsc";
+		reg = <0xaf20000 0x10000>;
+		reg-names = "drv-0";
+		interrupts = <GIC_SPI 129 IRQ_TYPE_LEVEL_HIGH>;
+		qcom,tcs-offset = <0x1c00>;
+		qcom,drv-id = <0>;
+		qcom,tcs-config = <ACTIVE_TCS  0>,
+				  <SLEEP_TCS   1>,
+				  <WAKE_TCS    1>,
+				  <CONTROL_TCS 0>;
+	};

In accordance with section 11 of
Documentation/process/submitting-patches.rst you must to add your
Signed-off-by tag at the end of this list.

Same on patch 3.
