Subject: [PATCH v4 8/13] arm64: allwinner: a64: Add MMC nodes
Date: Thu, 26 Jan 2017 10:06:01 +0100 [thread overview]
Message-ID: <a8a23bfa7d131a149c3cefb69737439aeb2572b5.1485421557.git-series.maxime.ripard@free-electrons.com> (raw)
In-Reply-To: <cover.8d42a39b7bd5143e709979dc42cc47862ebe3728.1485421557.git-series.maxime.ripard@free-electrons.com>
In-Reply-To: <cover.8d42a39b7bd5143e709979dc42cc47862ebe3728.1485421557.git-series.maxime.ripard@free-electrons.com>
From: Andre Przywara <andre.przywara@arm.com>
The A64 has 3 MMC controllers, one of them being especially targeted to
eMMC. Among other things, it has a data strobe signal and a 8 bits data
width.
The two other are more usual controllers that will have a 4 bits width at
most and no data strobe signal, which limits it to more usual SD or MMC
peripherals.
