Subject: [PATCH v2 2/7] arm64: dts: meson-sm1-odroid: set tf_io regulator gpio as open source
Date: Mon, 7 Jun 2021 08:54:30 +0200 [thread overview]
Message-ID: <20210607065435.577334-3-narmstrong@baylibre.com> (raw)
In-Reply-To: <20210607065435.577334-1-narmstrong@baylibre.com>
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.
