[PATCH 1/2] ARM64: dts: rockchip: add sdhci/emmc for rk3399

Tue May 10 17:02:54 PDT 2016


The bindings for rk3399's SDHCI + eMMC PHY have been accepted, so let's
support eMMC now.

Note that 'rockchip,rk3399-sdhci-5.1' is not documented, but per Heiko's
previous suggestion, we don't want to clutter the arasan doc, and it's
just a precautionary measure to have it.
