Device tree bindings for fan tach output connected to PWM controller with
|
||
|
|
PWM capture capability.
|
||
|
|
|
||
|
|
Required properties:
|
||
|
|
- compatible : "generic-pwm-tachometer"
|
||
|
|
- pwms : PWM handle. Please refer pwm.txt DT binding for more details.
|
||
|
|
|
||
|
|
Example:
|
||
|
|
|
||
|
|
tegra_tachometer: tachometer@39c0000 {
|
||
|
|
compatible = "nvidia,pwm-tegra194-tachometer";
|
||
|
|
reg = <0x0 0x039c0000 0x0 0x10>;
|
||
|
|
clocks = <&bpmp_clks TEGRA194_CLK_TACH>;
|
||
|
|
clock-names = "tach";
|
||
|
|
resets = <&bpmp_resets TEGRA194_RESET_TACH>;
|
||
|
|
reset-names = "tach";
|
||
|
|
pulse-per-rev = <2>;
|
||
|
|
sampling-window = <2>;
|
||
|
|
};

|
|
||
|
|
generic_pwm_tachometer {
|
||
|
