Hi,

This is v4 of the patch series to enable SD/MMC on the SOCFPGA platform.

V4 differences from V3:

* Re-use the SOCFPGA clock driver for controlling the SDR settings of the CIU
clock. By using the .prepare member of the common clk_ops structure, the settings
of the SD/MMC CIU can be done through the common clock API in the SD/MMC driver.

* Re-use exising binding that is on the Rockchip. The "rockchip,rk2928-dw-mshc"
binding that will also work for SOCFPGA.

* Remove dw_mmm-socfpga.c that is platform specific to SOCFPGA as the only
require platform specific code is already done with "rockchip,rk2928-dw-mshc".

* Add error checking for getting "samsung,dw-mshc-sdr-timing".

* Add support for SD/MMC to socfpga_defconfig.

* Add SD/MMC dts entries for socfpga_arria5.

Thanks,
