+description:
+ PWM modules inside Qualcomm Technologies, Inc. PMICs can be accessed through
+ SPMI bus and normally one PMIC would have multiple PWM modules with adjacent
+ SPMI address space.
+
+Properties:
+ compatible:
+ const: qcom,pwm
+
+ reg:
+ description:
+ The SPMI address base of the PWM module, if there are multiple PWM
+ modules present with adjacent SPMI address space, only need to specify
+ the address base of the 1st PWM module.
+
+ "#pwm-cells":
+ # See pwm.yaml in this directory for a description of the cells format.
+ const: 2
+
+ qcom,num-channels:
+ description:
+ The number of the PWM channels (modules) with the adjacent SPMI address
+ space following the address base in "reg" property.
+
+required:
+ - compatible
+ - reg
+ - "#pwm-cells"
+ - qcom,num-channels
+
+additionalProperties: false
+
+examples:
+ - |
+ pm8350c_pwm: pwms@e800 {
+ compatible = "qcom,pwm";
+ reg = <0xe800>;
+ #pwm-cells = <2>;
+ qcom,num-channels = <4>;
+ };
