1 Tegra SoC PWFM controller 2 3 Required properties: 4 - compatible: should be one of: 5 - "nvidia,tegra20-pwm" 6 - "nvidia,tegra30-pwm" 7 - reg: physical base address and length of the controller's registers 8 - #pwm-cells: On Tegra the number of cells used to specify a PWM is 2. The 9 first cell specifies the per-chip index of the PWM to use and the second 10 cell is the period in nanoseconds. 11 12 Example: 13 14 pwm: pwm@7000a000 { 15 compatible = "nvidia,tegra20-pwm"; 16 reg = <0x7000a000 0x100>; 17 #pwm-cells = <2>; 18 }; 19
