[PATCH 1/6] arm64: dts: meson-sm1-odroid: add missing enable gpio and supply for tf_io regulator

From: Neil Armstrong
Date: Tue Jun 01 2021 - 05:02:00 EST


As described in the schematics of Odroid-C4 and Odroid-HC4, the TF_IO regulator
is enabled by the GPIOE_2 GPIO and gets it's supply from VCC_5V.

Fixes: 88d537bc92ca ("arm64: dts: meson: convert meson-sm1-odroid-c4 to dtsi")
