From 13f35f6eb415ded8c3c7481e2a99d7d4d3833090 Mon Sep 17 00:00:00 2001 From: Birger Koblitz Date: Wed, 2 Feb 2022 07:29:25 +0100 Subject: [PATCH] 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.
