Subject: [PATCH v2 1/3] dt-bindings: pwm: msm-vibrator: new bindings for MSM vibrator PWM
Date: Wed, 26 Sep 2018 19:51:10 -0400	[thread overview]
Message-ID: <20180926235112.25710-2-masneyb@onstation.org> (raw)
In-Reply-To: <20180926235112.25710-1-masneyb@onstation.org>

This patch adds the device tree bindings for the vibrator PWM found on
various Qualcomm MSM SOCs.

+* Device tree bindings for the vibrator PWM on various MSM SOCs.
+
+Required properties:
+
+  - compatible: Should be one of
+		"qcom,msm8226-pwm-vibrator"
+		"qcom,msm8974-pwm-vibrator"
+  - reg: the base address and length of the IO memory for the registers.
+  - #pwm-cells: set to 3.
+  - pinctrl-names: set to default.
+  - pinctrl-0: phandles pointing to pin configuration nodes. See
+               Documentation/devicetree/bindings/pinctrl/pinctrl-bindings.txt
+  - clock-names: set to pwm
+  - clocks: phandle of the clock used by the PWM module. See
+            Documentation/devicetree/bindings/clock/clock-bindings.txt
+  - enable-gpios: GPIO that enables the PWM.
+
+Optional properties:
+
+  - vcc-supply: phandle to the regulator that provides power to the sensor.
+
+Example from a LG Nexus 5 (hammerhead) phone:
+
+msm_pwm_vibrator_enable: pwm@fd8c3450 {
+	reg = <0xfd8c3450 0x400>;
+	compatible = "qcom,msm8974-pwm-vibrator";
+	#pwm-cells = <3>;
+
+	vcc-supply = <&pm8941_l19>;
+
+	clocks = <&mmcc CAMSS_GP1_CLK>;
+	clock-names = "pwm";
+
+	enable-gpios = <&msmgpio 60 GPIO_ACTIVE_HIGH>;
+
+	pinctrl-names = "default";
+	pinctrl-0 = <&vibrator_pin>;
+};
