Subject: [PATCH] ARM: dts: exynos: add missing HDMI supplies on SMDK5420
Git-commit: 453a24ded415f7fce0499c6b0a2c7b28f84911f2
Patch-mainline: v5.18-rc1
References: git-fixes

Add required VDD supplies to HDMI block on SMDK5420.  Without them, the
HDMI driver won't probe.  Because of lack of schematics, use same
supplies as on Arndale Octa and Odroid XU3 boards (voltage matches).
