[cip-dev] [PATCH 4.4.y-cip 00/83] Add RZ/G1C SD/eMMC support

[biju.das@bp.renesas.com (Biju Das)]

This patch series add SD/eMMC support support for RZ/G1C sbc.

RZ/G1C eMMC IP is different from other RZ/G1 SoC's. It is having an 
internal DMA for data transfer which is similar to R-Car Gen3.

Support for internal DMAC is added in 4.14 kernel and support for 
RZ/G1C added on 4.20 kernel.

Backported the relevent patches to linux-4.4.y-cip.

This patch series is based on linux-4.4.y-cip and all the patches
in this series are cherry-picked from linux rc tree.
