1*beca1fdeSSimon GlassTegra SoC PWFM controller 2*beca1fdeSSimon Glass 3*beca1fdeSSimon GlassRequired properties: 4*beca1fdeSSimon Glass- compatible: should be one of: 5*beca1fdeSSimon Glass - "nvidia,tegra20-pwm" 6*beca1fdeSSimon Glass - "nvidia,tegra30-pwm" 7*beca1fdeSSimon Glass- reg: physical base address and length of the controller's registers 8*beca1fdeSSimon Glass- #pwm-cells: On Tegra the number of cells used to specify a PWM is 2. The 9*beca1fdeSSimon Glass first cell specifies the per-chip index of the PWM to use and the second 10*beca1fdeSSimon Glass cell is the period in nanoseconds. 11*beca1fdeSSimon Glass 12*beca1fdeSSimon GlassExample: 13*beca1fdeSSimon Glass 14*beca1fdeSSimon Glass pwm: pwm@7000a000 { 15*beca1fdeSSimon Glass compatible = "nvidia,tegra20-pwm"; 16*beca1fdeSSimon Glass reg = <0x7000a000 0x100>; 17*beca1fdeSSimon Glass #pwm-cells = <2>; 18*beca1fdeSSimon Glass }; 19
