Subject: [PATCH v4 11/13] arm64: allwinner: pine64: add MMC support
Date: Thu, 26 Jan 2017 10:06:04 +0100	[thread overview]
Message-ID: <b11557dbfbfa706605359ba334ffd13ba48946d8.1485421557.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>

All Pine64 boards connect an micro-SD card slot to the first MMC
controller.
Enable the respective DT node and specify the (always-on) regulator
and card-detect pin.
As a micro-SD slot does not feature a write-protect switch, we disable
this feature.
