== 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:
pwm0: pwm {
compatible = "st,stmpe-pwm";
#pwm-cells = <2>;
};
