49312c1f32 mmc: sh_mmcif, tmio: Use ARCH_RENESAS
Make use of ARCH_RENESAS in place of ARCH_SHMOBILE.

This is part of an ongoing process to migrate from ARCH_SHMOBILE to
ARCH_RENESAS the motivation for which being that RENESAS seems to be a more
appropriate name than SHMOBILE for the majority of Renesas ARM based SoCs.

a72e8b1700 mmc: sdhi: Add r8a7795 support
Registers are 64bit apart, so we refactor bus_shift handling a little and set
it based on the DT compatible. Also, EXT_ACC is different. It has been tested
on a Salvator-X (Gen3) and, to check for regressions, on a Lager (Gen2).

77cb7d3a4d mmc: sdhci-iproc: add bcm2835 support
Scott Branden from Broadcom said that the BCM2835 eMMC IP core is
very similar to IPROC and share most of the quirks. So use this driver
instead of separate one.

The sdhci-iproc contains a better workaround for the clock domain
crossing problem which doesn't need any delays. This results in a
better write performance.

Btw we get the rid of the SDHCI_CAPABILITIES hack in the sdhci_readl
function.

7f8a9a7e98 mmc: android-goldfish: Allow compiling the driver with COMPILE_TEST
The driver depends on GOLDFISH but there isn't a build dependency

That way, the driver can be built with a config generated by make

d0440c59f5 ARM: SoC cleanups for v4.1
We've got a fairly large cleanup branch this time. The bulk of this is removal
 of non-DT platforms of several flavors:
 
 - Atmel at91 platforms go full-DT, with removal of remaining board-file based
   support
 - OMAP removes legacy board files for three more platforms
 - Removal of non-DT mach-msm, newer Qualcomm platforms now live in mach-qcom
 - Freescale i.MX25 also removes non-DT platform support
 
 Most of the rest of the changes here are fallout from the above, i.e. for
 example removal of drivers that now lack platforms, etc.

The PPC_OF is a ppc specific option which is used to mean that the
firmware device tree access functions are available. Since all the
ppc platforms have a device tree, it is aways set to 'y' for ppc.
So it makes no sense to keep a such option in the current kernel.

controllers found in some older Toshiba laptops (such as Portege R100):

02:0d.0 System peripheral [0880]: Toshiba America Info Systems SD TypA Controller [1179:0805] (rev 05)

The code is fixed, cleaned up and successfully tested with SD, SDHC, SDXC and
MMC cards on Portege R100. (MMC cards don't even work in Windows!)
SDIO probably does not work (don't have any SDIO card).

The hardware is slow (around 2 MB/s - same in Windows) because it does not
support bus mastering (busmaster enable bit cannot be set in PCI control reg).
Also the card clock is limited to 16MHz (33MHz PCI clock divided by 2).

DML itself is not a DMA engine, its just a gule between the SD card

Most of this code has been ported from qualcomm's 3.4 kernel.

This patch adds the code necessary to intialize the hardware and setup
before doing any dma transfers.

5d01b7684b mmc: simplify SDHCI Kconfig dependencies
We have a number of front-end drivers for SDHCI_PLTFM, some of them
use 'select MMC_SDHCI_PLTFM', others use 'depends on'. This is
inconsistent and confusing, and in one case has also led to a
build error because of incomplete dependencies:

warning: (MMC_SDHCI_PXAV3 && MMC_SDHCI_PXAV2 && MMC_SDHCI_BCM_KONA) selects MMC_SDHCI_PLTFM which has unmet direct dependencies (MMC && MMC_SDHCI)
drivers/built-in.o: In function `sdhci_sirf_resume':
:(.text+0xaaacb4): undefined reference to `sdhci_resume_host'
drivers/built-in.o: In function `sdhci_sirf_suspend':
:(.text+0xaaacf8): undefined reference to `sdhci_suspend_host'
drivers/built-in.o: In function `sdhci_sirf_probe':
:(.text+0xaaaf44): undefined reference to `sdhci_add_host'
:(.text+0xaaaf50): undefined reference to `sdhci_remove_host'

This changes Kconfig to use 'depends on MMC_SDHCI_PLTFM' for all these
cases, to fix the build error and make the logic more logical.

60a549fcda mmc: omap: don't select TPS65010
The MMC host driver should not select the pmic driver, since that
may have other dependencies, notably i2c in this case. It's not
clear what the exact requirement of the driver is, but to preserve
the behavior, this patch changes the 'select' into 'depends on',
meaning you now have to turn on TPS65010 explicitly and then
MMC_OMAP.

Found during randconfig build testing.

DT-enabled Dove moved over from ARCH_DOVE in mach-dove to MACH_DOVE in
mach-mvebu. As non-DT ARCH_DOVE will stay to rot for a while, add a new
DT-only MACH_DOVE Kconfig. This slipped through the cracks and now is
a fix to allow to build Dove's SDHCI driver for mach-mvebu on v3.15-rc.

The Allwinner sunxi mmc host uses dma in bus-master mode using a built-in
designware idmac controller, which is identical to the one found in the
mmc-dw hosts. However the rest of the host is not identical to mmc-dw, it
deals with sending stop commands in hardware which makes it significantly
different from the mmc-dw devices.
