[PATCH v2 0/2] Add R8A7794/SILK board eMMC DT support

[Sergei Shtylyov]

Hello.

   Here's the set of 2 patches against Simon Horman's 'renesas.git' repo,
'renesas-devel-20150730-v4.2-rc4' tag. Here we add the eMMC device tree support
for the R8A7794-based SILK board.

[1/2] ARM: shmobile: r8a7794: add MMCIF DT support
[2/2] ARM: shmobile: silk: add eMMC DT support

WBR, Sergei

[PATCH v2 1/2] ARM: shmobile: r8a7794: add MMCIF DT support

[Sergei Shtylyov]

Define the generic R8A7794 part of the MMCIF0 device node.

Based on the orginal patch by Shinobu Uehara <shinobu.uehara.xc@renesas.com>.

Signed-off-by: Sergei Shtylyov <sergei.shtylyov@cogentembedded.com>

Changes in version  2:
- updated the patch due to the SDHI patch being accepted first;
- refreshed the patch.

[PATCH v2 2/2] ARM: shmobile: silk: add eMMC DT support

[Sergei Shtylyov]

Define the SILK board dependent part of the MMCIF device node (the board has
eMMC chip) along with the  necessary voltage regulator (note that the Vcc/Vccq
regulator is dummy -- it's required by the MMCIF driver but doesn't actually
exist on the board).

Based on the original patch by Vladimir Barinov
<vladimir.barinov@cogentembedded.com>.
