8cd46cba53 mmc: sd_sdhi: Enable clock using clock framework
Since we now have clock driver for the RCar Gen3 , add support for
enabling the clock into the SH SDHI driver to prevent hacks in the
board files.

a3f0a7d5b5 mmc: sh_sdhi: Fix the ACMD handling
The command handling in this driver is awful, esp. because the driver
depends on command numbers to determine whether this is APPCMD or not.
Also, handling of command RSP response types is totally wrong.

This patch at least plucks out some of the custom command encoding and
fixes the APPCMD handling. The RSP handling still needs work, yet that
might not be needed as it turns out the uniphier-sd.c driver is in much
better shape and supports the same IP, so we might be able to just drop
this driver in favor of the uniphier one.

d1c18ca110 mmc: sh_sdhi: Add DM and DT probing support
Add MMC DM and DT probing support into the SH SDHI driver.
This patch abstracts out the common bits of the send command
and set ios functions, so they can be used both by DM and non
DM setups and adds the DM probe support.

a5950f8dfb mmc: sh_sdhi: Add SDHI support
R-Car Gen3 series have four SD card interfaces (SDHI0 to SDHI3),
two of which can also be used as MMC interfaces (SDHI2 and SDHI3).
This adds High-speed mode SD clock frequency between 25MHz and 50MHz,
8bit/4bit bus width, high capacity and low voltage device support.

7593194685 mmc: rmobile: add a compiler barrier
Building w/ GCC v5.2, the SD card access is broken due to invalid data
in the response command reconstructed at the end of
sh_sdhci_get_response().

Add a memory barrier between the two main steps of this function to
ensure the resp[] table content is consistent before bits reordering.

This fix has been tested Ok on Porter board rev1.0 using v2016.03
release.
