Subject: [PATCH RESEND 3/3] arm64: dts: r8a7795: salvator-x: enable SDHI0 & 3
Date: Mon, 15 Feb 2016 16:01:50 +0100 [thread overview]
Message-ID: <1455548510-1690-4-git-send-email-wsa@the-dreams.de> (raw)
In-Reply-To: <1455548510-1690-1-git-send-email-wsa@the-dreams.de>
From: Ai Kyuse <ai.kyuse.uw@renesas.com>
Add the exposed SD card slots. The on-board eMMC needs to wait until we
fixed the 8bit support (it works with 4bit if you really want it now).
