Subject: [PATCH v3 4/5] ARM: dts: sun5i: Add port E pinmux settings for mmc2
Date: Tue, 16 May 2023 18:48:05 +0100 [thread overview]
Message-ID: <644b0a6aee41d205eb51d35365265ed63669707b.1684258957.git.noodles@earth.li> (raw)
In-Reply-To: <cover.1684258957.git.noodles@earth.li>
These alternate pins for mmc2 are brought out to the 40 pin U14 header
on the C.H.I.P and can be used to add an external MMC device with a 4
bit interface. See
https://byteporter.com/ntc-chip-micro-sd-slot/
for further details on how.
