1*4882a593SmuzhiyunTegra SoC PWFM controller
2*4882a593Smuzhiyun
3*4882a593SmuzhiyunRequired properties:
4*4882a593Smuzhiyun- compatible: should be one of:
5*4882a593Smuzhiyun  - "nvidia,tegra20-pwm"
6*4882a593Smuzhiyun  - "nvidia,tegra30-pwm"
7*4882a593Smuzhiyun- reg: physical base address and length of the controller's registers
8*4882a593Smuzhiyun- #pwm-cells: On Tegra the number of cells used to specify a PWM is 2. The
9*4882a593Smuzhiyun  first cell specifies the per-chip index of the PWM to use and the second
10*4882a593Smuzhiyun  cell is the period in nanoseconds.

13*4882a593Smuzhiyun
14*4882a593Smuzhiyun	pwm: pwm@7000a000 {
15*4882a593Smuzhiyun		compatible = "nvidia,tegra20-pwm";
16*4882a593Smuzhiyun		reg = <0x7000a000 0x100>;
17*4882a593Smuzhiyun		#pwm-cells = <2>;
