Subject: [PATCH v2 3/3] arm64: dts: a3720: add support for espressobin with populated emmc
Date: Fri,  4 Sep 2020 17:33:54 +0200	[thread overview]
Message-ID: <20200904153354.1120958-3-a.heider@gmail.com> (raw)
In-Reply-To: <20200904153354.1120958-1-a.heider@gmail.com>

Import armada-3720-espressobin-emmc.dts from Linux, but use sdhc1 for
emmc, since our dtsi is still based on downstream and sdhc0 is used for
the sd card.
