Tegra SoC PWFM controller
|
|
|
|
Required properties:
|
|
- compatible: should be one of:
|
|
- "nvidia,tegra20-pwm"
|
|
- "nvidia,tegra30-pwm"
|
|
- reg: physical base address and length of the controller's registers
|
|
- #pwm-cells: On Tegra the number of cells used to specify a PWM is 2. The
|
|
first cell specifies the per-chip index of the PWM to use and the second
|
|
cell is the duty cycle in nanoseconds.
|
|
|
|
Example:
|
|
|
|
pwm: pwm@7000a000 {
|
|
compatible = "nvidia,tegra20-pwm";
|
|
reg = <0x7000a000 0x100>;
|
|
#pwm-cells = <2>;
|
|
};
