Eric Anholt 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.

Douglas Anderson 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.

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.

Linus Torvalds d0440c59f5 ARM: SoC cleanups for v4.1

 - 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.

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.

Jean Delvare 82813b7198 mmc: Fix menuconfig alignment of MMC_SDHCI_* options
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
of all other MMC_SDHCI_* options in menuconfig.

	  If unsure, say Y.

However the option defaults to N. Set the default to Y to match the

Ondrej Zary 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).

to depend on HAS_DMA.  Since the drivers should build on any platform

Srinivas Kandagatla 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.
