From 012f3e37ca134da45af742a2d7971c513cb761d9 Mon Sep 17 00:00:00 2001 From: Adam Ford Date: Sun, 13 Dec 2020 12:37:47 -0600 Subject: [PATCH] arm64: dts: renesas: beacon: Fix LVDS PWM Backlight The backlight didn't really work correctly due to some updates that were made in hardware. It should be safe to apply these, because the older hardware was never shipped to anyone, so it shouldn't break anything.
