X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=27e8c8f3512371772b1fdd099466a8c198d05897;p=linux-beck.git

dt-bindings: pwm: Add DT bindings for STMPE PWM

This adds fairly standard device tree bindings for the STMPE PWM found
in STMPE24xx multi-purpose expanders.

+== 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>;
+};
