-BCM2835 PWM controller (Raspberry Pi controller)
-
-Required properties:
-- compatible: should be "brcm,bcm2835-pwm"
-- reg: physical base address and length of the controller's registers
-- clocks: This clock defines the base clock frequency of the PWM hardware
- system, the period and the duty_cycle of the PWM signal is a multiple of
- the base period.
-- #pwm-cells: Should be 3. See pwm.yaml in this directory for a description of
- the cells format.
-
-Examples:
-
-pwm@2020c000 {
- compatible = "brcm,bcm2835-pwm";
- reg = <0x2020c000 0x28>;
- clocks = <&clk_pwm>;
- #pwm-cells = <3>;
-};
-
-clocks {
- ....
- clk_pwm: pwm {
- compatible = "fixed-clock";
- reg = <3>;
- #clock-cells = <0>;
- clock-frequency = <9200000>;
- };
- ....
-};
