-This is a PWM block embedded in the ST Microelectronics STMPE

-subdevices of the STMPE MFD device.
-
-Required properties:
-- compatible: should be:
-  - "st,stmpe-pwm"
-- #pwm-cells: should be 2. See pwm.yaml in this directory for a description of
-  the cells format.

-Example:
-
-pwm0: pwm {

-	#pwm-cells = <2>;
