From 87c692fde46a511aa365d220588d0566125f4035 Mon Sep 17 00:00:00 2001 From: Chris Morgan Date: Fri, 12 May 2023 14:16:33 -0500 Subject: [PATCH] arm64: dts: rockchip: Update leds for Anbernic RGxx3 Series Each of the LEDs on the RGxx3 which is currently controlled via GPIO can also be controlled via a PWM. Change each of the LEDs to PWM so that users have the ability to adjust the brightness of the LEDs according to their preference.
