Tegra186 has 8 different PWM controllers and each controller has only one output. Earlier SoC generations have 4 PWM outputs per controller. Add a device tree compatible string for Tegra186 to be able to differentiate between the two.

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";
|
|
};
