Allwinner sun4i and sun7i SoC PWM controller
Required properties:
- compatible: should be one of:
- "allwinner,sun4i-a10-pwm"
- "allwinner,sun7i-a20-pwm"
- reg: physical base address and length of the controller's registers
- #pwm-cells: should be 3. See pwm.txt in this directory for a description of
the cells format.
- clocks: From common clock binding, handle to the parent clock.
Example:
pwm: pwm@01c20e00 {
compatible = "allwinner,sun7i-a20-pwm";
reg = <0x01c20e00 0xc>;
clocks = <&osc24M>;
#pwm-cells = <3>;
status = "disabled";
};
