··· 1 - * NXP LPC18xx State Configurable Timer - Pulse Width Modulator driver 2 - 3 - Required properties: 4 - - compatible: Should be "nxp,lpc1850-sct-pwm" 5 - - reg: Should contain physical base address and length of pwm registers. 6 - - clocks: Must contain an entry for each entry in clock-names. 7 - See ../clock/clock-bindings.txt for details. 8 - - clock-names: Must include the following entries. 9 - - pwm: PWM operating clock. 10 - - #pwm-cells: Should be 3. See pwm.yaml in this directory for the description 11 - of the cells format. 12 - 13 - Example: 14 - pwm: pwm@40000000 { 15 - compatible = "nxp,lpc1850-sct-pwm"; 16 - reg = <0x40000000 0x1000>; 17 - clocks =<&ccu1 CLK_CPU_SCT>; 18 - clock-names = "pwm"; 19 - #pwm-cells = <3>; 20 - };
