+== ST STMPE PWM controller ==
+
+This is a PWM block embedded in the ST Microelectronics STMPE
+(ST Multi-Purpose Expander) chips. The PWM is registered as a
+subdevices of the STMPE MFD device.
+
+Required properties:
+- compatible: should be:
+ - "st,stmpe-pwm"
+- #pwm-cells: should be 2. See pwm.txt in this directory for a description of
+ the cells format.
+
+Example:
+
+stmpe1_pwm0: stmpe_pwm {
+ compatible = "st,stmpe-pwm";
+ #pwm-cells = <2>;
+};
