1 TI/National Semiconductor LP3943 PWM controller
4 - compatible: "ti,lp3943-pwm"
5 - #pwm-cells: Should be 2. See pwm.yaml in this directory for a
6 description of the cells format.
7 Note that this hardware limits the period length to the
9 - ti,pwm0 or ti,pwm1: Output pin number(s) for PWM channel 0 or 1.
17 PWM 0 is for RGB LED brightness control
18 PWM 1 is for brightness control of LP8557 backlight device
