From cc68a8a3f89c18bdbce33a449c31e6467a3cbcfa Mon Sep 17 00:00:00 2001 From: Chen-Yu Tsai Date: Mon, 2 Mar 2026 23:27:22 +0800 Subject: [PATCH] arm64: dts: allwinner: sun55i-t527: avaota-a1: Enable LEDs The Avaota A1 board features 4 RGB LEDs in a string connected to the SoC's LED controller. Enable the LED controller and add device nodes for them. The timings were copied from the downstream vendor DTS. The design does not specify what these LEDs are for, nor are there any markings on the board for them, so just use them as indicators.
