2020-07-20	backlight: Use backlight_get_brightness() throughout	Sam Ravnborg	1	-6/+1
	Introduce the backlight_get_brightness() helper in all video/backlight/* drivers. This simplifies the code and align the implementation of the update_status() operation across the different backlight drivers. Some of the drivers gains a little extra functionality by the change as they now respect the fb_blank() ioctl.

2020-02-20	backlight: add led-backlight driver	Tomi Valkeinen	1	-0/+260
	This patch adds a led-backlight driver (led_bl), which is similar to pwm_bl except the driver uses a LED class driver to adjust the brightness in the HW. Multiple LEDs can be used for a single backlight.
