This patch updates pwm-vt8500.c to support devicetree probing and make use of the common clock subsystem. A binding document describing the PWM controller found on arch-vt8500 is also included.

VIA/Wondermedia VT8500/WM8xxx series SoC PWM controller
|
|
|
|
Required properties:
|
|
- compatible: should be "via,vt8500-pwm"
|
|
- reg: physical base address and length of the controller's registers
|
|
- #pwm-cells: should be 2. The first cell specifies the per-chip index
|
|
of the PWM to use and the second cell is the period in nanoseconds.
|
|
- clocks: phandle to the PWM source clock
|
|
|
|
Example:
|
|
|
|
pwm1: pwm@d8220000 {
|
|
#pwm-cells = <2>;
|
|
compatible = "via,vt8500-pwm";
|
|
reg = <0xd8220000 0x1000>;
|
|
clocks = <&clkpwm>;
|
|
};
