Subject: [PATCH mvebu-dt64] arm64: dts: armada-3720-turris-mox.dts: fix sdhci1 pins
Date: Wed, 13 May 2020 19:56:48 +0200	[thread overview]
Message-ID: <20200513175648.GA7561@dumbo> (raw)

From: Domenico Andreoli <domenico.andreoli@linux.com>

In order to use the sdcard slot on Turris MOX it is necessary to mux
the sdio0 pins in the north-bridge, which are herein also added.

This fixes the boot problem reported at [0].
