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>;
|
||||
};
