HWKM (Hardware Key Manager)

The HWKM driver is a platform device driver that helps

communicating with both the master and slave blocks of the

hardware key manager to issue commands to perform key operations

mainly required for storage encryption.

Required properties:

- compatible : Should be "qcom,hwkm".

- reg: Register set for both master and slaves.

- reg-names : Identifiers for parsing master and slave regs.

- clocks : clocks needed for operating master and the slave.

- clock-names : name identifiers corresponding to the clocks.

- qcom,enable-hwkm-clk: to ensure clocks can be handled by HLOS.

- qcom,op-freq-hz: Max frequency of the listed clocks.

Example:

	qcom_hwkm: hwkm@10c0000 {

		compatible = "qcom,hwkm";

		reg = <0x10c0000 0x9000>, <0x1d90000 0x9000>;

		reg-names = "km_master", "ice_slave";

		qcom,enable-hwkm-clk;

		clock-names = "km_clk_src";

		clocks = <&clock_rpmh RPMH_HWKM_CLK>;

		qcom,op-freq-hz = <75000000>;

	};

		qca,qca6174

		qca,wcn3990

                qca,qca6390

		qca,wcn6750

	- qca,bt-reset-gpio: GPIO pin to bring BT Controller out of reset

Optional properties:

					0 = default value.

- qcom,mdss-dsi-bl-max-level:		Specifies the max backlight level supported by the panel.

					255 = default value.

- qcom,mdss-dsi-bl-inverted-dbv:	A boolean to specify whether to invert the display brightness value.

					When this boolean is set, will inverted display brightness value.

- qcom,mdss-brightness-max-level:	Specifies the max brightness level supported.

					255 = default value.

- qcom,bl-update-flag:			A string that specifies controls for backlight update of the panel.

                     be specified if a group of flash LED channels are connected

                     to a single LED.

- qcom,ibatt-ocp-threshold-ua : Integer property for flash current predictive mitigation.

				  Default value is 2500000 uA.

Example:

qcom,leds@ee00 {

	will load LPASS Q6 for other targets as expected.

	"adsp" option need not be explicitly mentioned in

	DTSI file, as it is default option.

 - adsp-fuse-not-supported:

	When ADSP variant read from fuse register is not

	supported, set this to true to check if image with different fw image

	name needs to be loaded

 - adsp-fw-name:

	ADSP fw name with which PIL API to load DSP needs to be called

Example:

	compatible = "qcom,adsp-loader";

	qcom,adsp-state = <2>;

	qcom,proc-img-to-load = "modem";

	adsp-fuse-not-supported = <1>;

	adsp-fw-name = "adsp2";
