devicetree: pwm: mxs-pwm.txt: Fix reg field annotation
[can-eth-gw-linux.git] / Documentation / devicetree / bindings / pwm / mxs-pwm.txt
1 Freescale MXS PWM controller
2
3 Required properties:
4 - compatible: should be "fsl,imx23-pwm"
5 - reg: physical base address and length of the controller's registers
6 - #pwm-cells: should be 2.  The first cell specifies the per-chip index
7   of the PWM to use and the second cell is the duty cycle in nanoseconds.
8 - fsl,pwm-number: the number of PWM devices
9
10 Example:
11
12 pwm: pwm@80064000 {
13         compatible = "fsl,imx28-pwm", "fsl,imx23-pwm";
14         reg = <0x80064000 0x2000>;
15         #pwm-cells = <2>;
16         fsl,pwm-number = <8>;
17 };
