Subject: [PATCH 90/96] leds: turris-omnia: change max brightness from 255 to 1
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
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.
