Broadcom BCM7038 PWM controller (BCM7xxx Set Top Box PWM controller)
|
|
|
|
Required properties:
|
|
|
|
- compatible: must be "brcm,bcm7038-pwm"
|
|
- reg: physical base address and length for this controller
|
|
- #pwm-cells: should be 2. See pwm.txt in this directory for a description
|
|
of the cells format
|
|
- clocks: a phandle to the reference clock for this block which is fed through
|
|
its internal variable clock frequency generator
|
|
|
|
|
|
Example:
|
|
|
|
pwm: pwm@f0408000 {
|
|
compatible = "brcm,bcm7038-pwm";
|
|
reg = <0xf0408000 0x28>;
|
|
#pwm-cells = <2>;
|
|
clocks = <&upg_fixed>;
|
|
};
