Subject: [PATCH] leds: turris-omnia: change max brightness from 255 to 1

Using binary brightness makes more sense for this controller, because
|
|
|
|
|
internally in the MCU it works that way: the LED has a color, and a
|
|
|
|
|
state whether it is ON or OFF.
|
|
|
|
|
|
|
|
|
|
The resulting brightness computation with led_mc_calc_color_components()
|
|
|
|
|
will now always result in either (0, 0, 0) or the multi_intensity value.
