Tegra SoC PWFM controller
Required properties:
- compatible: Must be:
- "nvidia,tegra20-pwm": for Tegra20
- "nvidia,tegra30-pwm", "nvidia,tegra20-pwm": for Tegra30
- "nvidia,tegra114-pwm", "nvidia,tegra20-pwm": for Tegra114
- "nvidia,tegra124-pwm", "nvidia,tegra20-pwm": for Tegra124
- "nvidia,tegra132-pwm", "nvidia,tegra20-pwm": for Tegra132
- "nvidia,tegra210-pwm", "nvidia,tegra20-pwm": for Tegra210
- "nvidia,tegra186-pwm": for Tegra186
- 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: Must contain one entry, for the module clock.
See ../clocks/clock-bindings.txt for details.
- resets: Must contain an entry for each entry in reset-names.
See ../reset/reset.txt for details.
- reset-names: Must include the following entries:
- pwm
Example:
pwm: pwm@7000a000 {
compatible = "nvidia,tegra20-pwm";
reg = <0x7000a000 0x100>;
#pwm-cells = <2>;
clocks = <&tegra_car 17>;
resets = <&tegra_car 17>;
reset-names = "pwm";
};
