b5b6a5f4f0 mmc: renesas-sdhi: rename sh_mobile_sdhi.c => renesas_sdhi_core.c
Rename the source file SDHI. A follow-up patch will make it a library
file used by a different top-level module file.

The name "renesas" is chosen as the SDHI driver is applicable to a wider
range of SoCs than SH-Mobile it seems to be a more appropriate name.
However, the SDHI driver source itself, is left as sh_mobile_sdhi to
avoid unnecessary churn.

the name "core" was chosen to reflect the desired role of this file,
to provide core functionality to the sdhi driver. A follow-up patch will
move the file into that role.

Internal symbols have also been renamed to reflect the filename change.

The .name member of struct platform_driver and parameter to
MODULE_ALIAS() have not been changed in order to avoid the complication
of potentially breaking SH SoCs which still use platform drivers.

660fc733bd mmc: bcm2835: Add new driver for the sdhost controller.
The 2835 has two SD controllers: The Arasan sdhci controller (supported
by the iproc driver) and a custom sdhost controller.  This patch adds a
driver for the latter.

The sdhci controller supports both sdcard and sdio.  The sdhost
controller supports the sdcard only, but has better performance.  Also
note that the rpi3 has sdio wifi, so driving the sdcard with the sdhost
controller allows to use the sdhci controller for wifi support.

The configuration is done by devicetree via pin muxing.  Both SD
controller are available on the same pins (2 pin groups = pin 22 to 27 +
pin 48 to 53).  So it's possible to use both SD controllers at the same
time with different pin groups.

The code was originally written by Phil Elwell in the downstream
Rasbperry Pi tree.   In preparation for the upstream merge it was
cleaned up and the code base was moderized by Eric Anholt, Stefan
Wahren and Gerd Hoffmann.

c390f2110a mmc: sdhci-of-arasan: Add ability to export card clock
Some SD/eMMC PHYs (like the PHY from Arasan that is designed to work
with arasan,sdhci-5.1) need to know the card clock in order to function
properly.  Let's add the ability to expose this clock.  Any PHY that
needs to know the clock rate can add a reference and query the clock
rate.

At the moment we register a CLK_GET_RATE_NOCACHE clock that simply
allows querying the clock.  This allows us to be less intrusive with
regards to the main SDHCI driver, which has complex logic for adjusting
the SD clock.  Right now we always fully power cycle the PHY when the
clock changes and that gives the PHY a good chance to query our clock.

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.

 - OMAP removes legacy board files for three more platforms
 - Removal of non-DT mach-msm, newer Qualcomm platforms now live in mach-qcom

It was brought to my attention that the sdhci-pxav3 driver is needed
on a few more ARM machines than I initially thought. Add the missing
architectures to the dependency list.

Credits to Peter Robinson for noticing my mistake and reporting.

5f2e097ce0 mmc: kconfig: replace PPC_OF with PPC
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.
Replace it with PPC.

8a8735eb4c mmc: Add hardware dependencies for sdhci-pxav3 and sdhci-pxav2
I seem to understand that the sdhci-pxav3 and sdhci-pxav2 drivers are
only needed on the MMP architecture. So add a hardware dependency on
ARCH_MMP, so that other users don't get to build useless drivers.

Let MMC_SDHCI_BIG_ENDIAN_32BIT_BYTE_SWAPPER depend on MMC_SDHCI. Not
only this is more correct, but this also avoids breaking the alignment

a5eb8bbd66 mmc: add Toshiba PCI SD controller driver
This patch resurrects an old never-finished driver for Toshiba PCI SD
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).

9cb15142d0 mmc: mmci: Add qcom dml support to the driver.
On Qualcomm APQ8064 SOCs, SD card controller has an additional glue
called DML (Data Mover Local/Lite) to assist dma transfers.
This hardware needs to be setup before any dma transfer is requested.
DML itself is not a DMA engine, its just a gule between the SD card
controller and dma controller.

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.
