Subject: [PATCHv2] arm64: dts: exynos: add the mshc_2 node for supporting
 T-Flash
Date: Mon, 21 Nov 2016 13:58:39 +0900
Message-id: <20161121045839.1444-1-jh80.chung@samsung.com>

Add the mshc_2 node for supporting T-flash.

And it needs to add the "mshc*" aliases. Because dwmmc driver should be
assigned to "ctrl_id" after parsing to "mshc".
If there is no aliases for mshc, then it might be set to the wrong
capabilities.
