[PATCH] arm64: dts: hihope-rzg2-ex-lvds: Add power-supply and enable-gpios to backlight node

From: Lad Prabhakar
Date: Sun Nov 21 2021 - 18:58:17 EST


This patch adds missing power-supply and enable-gpios property to
backlight node. This fixes the warning "pwm-backlight backlight:
backlight supply power not found, using dummy regulator".
