[PATCH 2/4] backlight: Expose brightness curve type through sysfs

2019-06-13 Thread Matthias Kaehlcke
Backlight brightness curves can have different shapes. The two main types are linear and non-linear curves. The human eye doesn't perceive linearly increasing/decreasing brightness as linear (see also 88ba95bedb79 "backlight: pwm_bl: Compute brightness of LED linearly to human eye"), hence many
