Subject[PATCH 5.10 080/563] arm64: dts: meson-gxbb-wetek: fix HDMI in early boot
Date
From: Christian Hewitt <christianshewitt@gmail.com>

[ Upstream commit 8182a35868db5f053111d5d9d4da8fcb3f99259d ]

Mark the VDDIO_AO18 regulator always-on and set hdmi-supply for the hdmi_tx
node to ensure HDMI is powered in the early stages of boot.
