[RFC v2 1/2] backlight: pwm_bl: linear interpolation between values of brightness-levels

2017-11-16 Thread Enric Balletbo i Serra
Setting use-linear-interpolation in the dts will allow you to have linear interpolation between values of brightness-levels. There are now 256 between each of the values of brightness-levels. If something is requested halfway between 2 values, we'll use linear interpolation. This way a high resol
