It backports this patch series, which is currently on review: https://lore.kernel.org/linux-leds/20220704105955.15474-1-kabel@kernel.org/T/#rb89a4ca5a836f17bdcc53d65549e0b1779bb6a18 It allows being able to configure LEDs in userspace. This fixes issue described in Turris Build repository https://gitlab.nic.cz/turris/os/build/-/issues/354 It happens in OpenWrt as well. - Before ``` root@turris:/# ls /sys/class/leds/ ath10k-phy0 ath9k-phy1 mmc0:: ``` -After ``` root@turris:/# ls /sys/class/leds/ ath10k-phy0 rgb:indicator-2 rgb:lan-3 rgb:wlan-1 ath9k-phy1 rgb:lan-0 rgb:lan-4 rgb:wlan-2 mmc0:: rgb:lan-1 rgb:power rgb:wlan-3 rgb:indicator-1 rgb:lan-2 rgb:wan ``` Signed-off-by: Josef Schlehofer <pepe.schlehofer@gmail.com>

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.
