The usage of the label property for gpio-leds has been deprecated a long time ago. In bcm2835-rpi.dtsi the ACT LED uses such a label and derive it to almost every Raspberry Pi board. Since we cannot break userspace interface this property must be kept. But we can move the ACT LED into a separate dtsi and include them from the board files. This change have two benefits: - with both new refs it's now clear the LED part is included from a dtsi - new boards do not include the deprecated stuff automatically Reported-by: Alexander Dahl <ada@thorsis.com> Signed-off-by: Stefan Wahren <stefan.wahren@i2se.com> Link: https://lore.kernel.org/r/20221110173105.6633-3-stefan.wahren@i2se.com Signed-off-by: Florian Fainelli <f.fainelli@gmail.com>
