* MSM Gladiator error reporting driver

Required properties:

- compatible: Should be "qcom,msm-gladiator" or "qcom,msm-gladiator-v2" or

"qcom,msm-gladiator-v3"

- reg: I/O address Gladiator H/W block

- reg-names: Should be "gladiator_base"

- interrupts: Should contain the gladiator error interrupt number

- clock-names: Should be "atb_clk"

- clocks: Handles to clocks specified in "clock-names" property.

Example:

qcom,msm-gladiator-v2@b1c0000 {

	compatible = "qcom,msm-gladiator";

	reg = <0xb1c0000 0xe000>;

	reg-names = "gladiator_base";

	interrupts = <0 34 0>;

	clock-names = "atb_clk";

	clocks = <&clock_gcc clk_qdss_clk>;

Resource Power Manager(RPM)

RPM is a dedicated hardware engine for managing shared SoC resources,

which includes buses, clocks, power rails, etc.  The goal of RPM is

to achieve the maximum power savings while satisfying the SoC's

operational and performance requirements.  RPM accepts resource

requests from multiple RPM masters.  It arbitrates and aggregates

the requests, and configures the shared resources. The RPM masters

are the application processor, the modem processor, as well as hardware

accelerators. The RPM driver communicates with the hardware engine using

SMD.

The devicetree representation of the RPM block should be:

Required properties

- compatible: "qcom,rpm-smd"

- rpm-channel-name: The string corresponding to the channel name of the

			peripheral subsystem. Required for both smd and

			glink transports.

- rpm-channel-type: The interal SMD edge for this subsystem found in

			<soc/qcom/smd.h>

- interrupts: The IRQ used by remote processor to inform APSS about

				reception of response message packet.

Optional properties

- rpm-standalone: Allow RPM driver to run in standalone mode irrespective of RPM

			channel presence.

- reg: Contains the memory address at which rpm messaging format version is

  stored. If this field is not present, the target only supports v0 format.

Example:

	qcom,rpm-smd {

		compatible = "qcom,rpm-smd";

		interrupts = <GIC_SPI 194 IRQ_TYPE_EDGE_RISING>;

		qcom,rpm-channel-name = "rpm_requests";

		qcom,rpm-channel-type = 15; /* APPS_RPM_SMD */

	}

}

* RPM Stats

RPM maintains a counter of the masters i.e APPS, MPPS etc

number of times the SoC entered a deeper sleep mode involving

lowering or powering down the backbone rails - Cx and Mx and

the oscillator clock, XO.

PROPERTIES

- compatible:

	Usage: required

	Value type: <string>

	Definition: Should be "qcom,rpm-master-stats".

- reg:

	Usage: required

	Value type: <prop-encoded-array>

	Definition: The address on the RPM RAM from where the stats are read

	            should be provided as "phys_addr_base". The offset

		    from which the stats are available should be provided as

		    "offset_addr".

- reg-names:

	Usage: required

	Value type: <prop-encoded-array>

	Definition: Provides labels for the reg property.

- qcom,masters:

	Usage: required

	Value tye: <string list>

	Defination: Provides the masters list.

qcom,master-offset:

	Usage: required

	Value tye: <prop-encoded-array>

	Defination: Provides the masters list

EXAMPLE:

qcom,rpm-master-stats@60150 {

		compatible = "qcom,rpm-master-stats";

		reg = <0x45f0150 0x5000>;

		qcom,masters = "APSS", "MPSS", "ADSP", "CDSP", "TZ";

		qcom,master-stats-version = <2>;

		qcom,master-offset = <4096>;

	};

		      order as the clocks property.

- qcom,keep-radio-on-during-sleep: Boolean flag to indicate if to suspend to d3hot

				   instead of turning off the device

- qcom,use-ap-power-save: Boolean flag to indicate if AP power save feature is

			  enabled

Example:

	wil6210: qcom,wil6210 {

			 <&clock_gcc clk_rf_clk3_pin>;

		clock-names = "rf_clk3_clk", "rf_clk3_pin_clk";

		qcom,keep-radio-on-during-sleep;

		qcom,use-ap-power-save;

	};
