[PATCH v3 7/7] devicetree: bindings: Document PM8921/8058 PMICs

From: Stephen Boyd <hidden>
Date: 2014-01-08 18:38:12
Also in: linux-arm-msm, linux-devicetree, lkml
Subsystem: arm/qualcomm mailing list, multifunction devices (mfd), open firmware and flattened device tree bindings, the rest · Maintainers: Lee Jones, Rob Herring, Krzysztof Kozlowski, Conor Dooley, Linus Torvalds

PM8921 and PM8058 are PMICs found paired with MSM8960 and MSM8660
devices respectively. They contain subdevices such as keypads,
RTCs, regulators, clocks, etc.

+PROPERTIES
+
+- compatible:
+	Usage: required
+	Value type: <string>
+	Definition: must be one of:
+		    "qcom,pm8058"
+		    "qcom,pm8921"
+
+- #address-cells:
+	Usage: required
+	Value type: <u32>
+	Definition: must be 1
+
+- #size-cells:
+	Usage: required
+	Value type: <u32>
+	Definition: must be 0
+
+- interrupts:
+	Usage: required
+	Value type: <prop-encoded-array>
+	Definition: specifies the interrupt that indicates a subdevice
+		    has generated an interrupt (summary interrupt). The
+		    format of the specifier is defined by the binding document
+		    describing the node's interrupt parent.
+
+- #interrupt-cells:
+	Usage: required
+	Value type : <u32>
+	Definition: must be 2. Specifies the number of cells needed to encode
+		    an interrupt source. The 1st cell contains the interrupt
+		    number. The 2nd cell is the trigger type and level flags
+		    encoded as follows:
+
+			1 = low-to-high edge triggered
+			2 = high-to-low edge triggered
+			4 = active high level-sensitive
+			8 = active low level-sensitive
+
+- interrupt-controller:
+	Usage: required
+	Value type: <empty>
+	Definition: identifies this node as an interrupt controller
+
+EXAMPLE
+
+	pmicintc: pmic at 0 {
+		compatible = "qcom,pm8921";
+		interrupts = <104 8>;
+		#interrupt-cells = <2>;
+		interrupt-controller;
+		#address-cells = <1>;
+		#size-cells = <0>;
+
+		pwrkey {
+			compatible = "qcom,pm8921-pwrkey";
+			interrupt-parent = <&pmicintc>;
+			interrupts = <50 1>, <51 1>;
+		};
+	};
