From: Birger Koblitz Date: Wed, 2 Feb 2022 06:29:25 +0000 (+0100) Subject: realtek: add support for port led configuration on RTL93XX X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=0538dc693b54e52fdfb8b7cd052eb96b5eb65708;p=openwrt%2Fstaging%2Fstintel.git realtek: add support for port led configuration on RTL93XX Using the led-set attribute of a port in the dts we allow configuration of the port leds. Each led-set is being defined in the led-set configuration of the .dts, giving a specific configuration to steer the port LEDs via a serial connection.
