Subject: [PATCH] arm64: dts: meson-g12b-odroid-n2: add 5v regulator gpio
Date: Sun, 19 Sep 2021 21:31:34 +0000 [thread overview]
Message-ID: <20210919213135.4928-1-linux.amoon@gmail.com> (raw)
As described in the Odroid-n2 & Odroid-n2-plus schematics,
the 5V regulator is controlled by GPIOH_8 and in Open Drain
since this GPIO doesn't support Push-Pull.
