Subject: [PATCH] arm64: dts: rockchip: Add sdio node to rock-5b
Message-ID: <20230924203740.65744-1-tszucs@protonmail.ch>
Feedback-ID: 53029:user:proton
MIME-Version: 1.0
Content-Type: text/plain; charset=utf-8
Content-Transfer-Encoding: quoted-printable
Precedence: bulk

Enable SDIO on Radxa ROCK 5 Model B M.2 Key E. Add sdio node and alias as m=
mc2.
Add regulator for the 3.3 V rail bringing it up during boot. Make sure EKEY=
_EN
is muxed as GPIO.
