1== ST SPEAr SoC PWM controller == 2 3Required properties: 4- compatible: should be one of: 5 - "st,spear320-pwm" 6 - "st,spear1340-pwm" 7- reg: physical base address and length of the controller's registers 8- #pwm-cells: number of cells used to specify PWM which is fixed to 2 on 9 SPEAr. The first cell specifies the per-chip index of the PWM to use and 10 the second cell is the period in nanoseconds. 11 12Example: 13 14 pwm: pwm@a8000000 { 15 compatible ="st,spear320-pwm"; 16 reg = <0xa8000000 0x1000>; 17 #pwm-cells = <2>; 18 }; 19
