Subject: [PATCH 1/3] arm64: dts: Pine64: add MMC support
Date: Tue, 10 Jan 2017 01:22:31 +0000 [thread overview]
Message-ID: <1484011353-21480-2-git-send-email-andre.przywara@arm.com> (raw)
In-Reply-To: <1484011353-21480-1-git-send-email-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.
