Add a new driver for the ARM CLPS711X Pulse Width Modulator (PWM) interface. This CPU contain two 4-bit PWM outputs with constant period, based on CPU PLL frequency. PWM polarity is determined by hardware by power on reset. Signed-off-by: Alexander Shiyan <shc_work@mail.ru> Signed-off-by: Thierry Reding <thierry.reding@gmail.com>

* Cirris Logic CLPS711X PWM controller
|
|
|
|
Required properties:
|
|
- compatible: Shall contain "cirrus,clps711x-pwm".
|
|
- reg: Physical base address and length of the controller's registers.
|
|
- clocks: phandle + clock specifier pair of the PWM reference clock.
|
|
- #pwm-cells: Should be 1. The cell specifies the index of the channel.
|
|
|
|
Example:
|
|
pwm: pwm@80000400 {
|
|
compatible = "cirrus,ep7312-pwm",
|
|
"cirrus,clps711x-pwm";
|
|
reg = <0x80000400 0x4>;
|
|
clocks = <&clks 8>;
|
|
#pwm-cells = <1>;
|
|
};
