[PATCH 2/6] arm64: dts: meson-sm1-odroid: set tf_io regulator gpio as open source

From: Neil Armstrong <hidden>
Date: 2021-06-01 09:01:53
Also in: linux-amlogic, lkml
Subsystem: arm/amlogic meson soc support, the rest · Maintainers: Neil Armstrong, Kevin Hilman, Linus Torvalds

According to Odroid-C4 & HC4 Schematics, the TF_3V3N_1V8_EN can be in Hi-Z for 3v3,
and since it's the default GPIOAO_6 mode at reset, let switch this GPIO as Open-Source
to drive for 1, and input for 0.

Fixes: 88d537bc92ca ("arm64: dts: meson: convert meson-sm1-odroid-c4 to dtsi")
Signed-off-by: Neil Armstrong <redacted>
