PM8921 and PM8058 are PMICs found paired with MSM8960 and MSM8660
devices respectively. They contain subdevices such as keypads,
RTC, 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@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>;
+ };
+ };
