Subject: [PATCH v2 5/7] arm64: dts: meson-sm1-odroid-hc4: add regulators controlled by GPIOH_8
Date: Mon,  7 Jun 2021 08:54:33 +0200	[thread overview]
Message-ID: <20210607065435.577334-6-narmstrong@baylibre.com> (raw)
In-Reply-To: <20210607065435.577334-1-narmstrong@baylibre.com>

As described in the HC4 schematics, GPIOH_8 controls the USB 5V and 12V
regulators used to power the SATA drives.

And is set as Open Drain since this GPIO doesn't support Push-Pull.
