In expectation of a bcm2835 clock driver, I've added fixed-clock clock binding. --- Changes in v2: - status set to disabled - follow the clock naming convention Signed-off-by: Bart Tanghe diff --git a/arch/arm/boot/dts/bcm2835.dtsi b/arch/arm/boot/dts/bcm2835.dtsi index 3342cb1..ba76bb4 100644 --- a/arch/arm/boot/dts/bcm2835.dtsi +++ b/arch/arm/boot/dts/bcm2835.dtsi @@ -146,6 +147,14 @@ interrupts = <1 9>; }; + pwm: pwm@7e20e000 { + compatible = "brcm,bcm2835-pwm"; + reg = <0x7e20c000 0x28>; + clocks = <&clk_pwm>; + #pwm-cells = <2>; + status = "disabled"; + }; + arm-pmu { compatible = "arm,arm1176-pmu"; }; @@ -179,5 +188,13 @@ clock-output-names = "spi"; clock-frequency = <250000000>; }; + + clk_pwm: clock@3 { + compatible = "fixed-clock"; + reg = <3>; + #clock-cells = <0>; + clock-output-names = "pwm"; + clock-frequency = <9200000>; + }; }; };
