Freescale i.MX PWM controller
Required properties:
- compatible : should be "fsl,<soc>-pwm" and one of the following
compatible strings:
- "fsl,imx1-pwm" for PWM compatible with the one integrated on i.MX1
- "fsl,imx27-pwm" for PWM compatible with the one integrated on i.MX27
- reg: physical base address and length of the controller's registers
- #pwm-cells: should be 2. See pwm.txt in this directory for a description of
the cells format.
- clocks : Clock specifiers for both ipg and per clocks.
- clock-names : Clock names should include both "ipg" and "per"
See the clock consumer binding,
Documentation/devicetree/bindings/clock/clock-bindings.txt
- interrupts: The interrupt for the pwm controller
Example:
pwm1: pwm@53fb4000 {
#pwm-cells = <2>;
compatible = "fsl,imx53-pwm", "fsl,imx27-pwm";
reg = <0x53fb4000 0x4000>;
clocks = <&clks IMX5_CLK_PWM1_IPG_GATE>,
<&clks IMX5_CLK_PWM1_HF_GATE>;
clock-names = "ipg", "per";
interrupts = <61>;
};
