Due to unknown hw issue so far, Merrifield is unable to enable HS200
support. This patch adds quirk to avoid SDHCI to initialize with error

ff0fa48f81 mmc: sdhi: Enable driver compilation with COMPILE_TEST
This helps increasing build testing coverage.

The driver doesn't compile on (at least) x86 due (possibly among others)
to missing readsw/writesw I/O accessors, restrict compilation to SUPERH
or ARM.

Whether the CTL_DMA_ENABLE register is part of the standard TMIO
controller or is Renesas-specific is unknown and impossible to test as
we have no current or planned TMIO DMA users other than SUPERH and
ARCH_SHMOBILE. Writing to the register is thus conditionally compiled
for SUPERH and ARCH_SHMOBILE only. Adding ARCH_SHMOBILE_MULTI to the
list would extend this to multiarch kernels, but would break the driver
for non-shmobile platforms if the register is Renesas-specific. We can
thus get rid of the conditional compilation completely without
introducing any further issue, and let future non-Renesas users deal
with the situation if it turns out to be a the problem.

67debea344 mmc: tegra: add support for Tegra124
Tegra124's MMC controller is very similar to earlier SoC generations,
and can be supported by the same driver.

However, there are some non-backwards-compatible HW differences, and
hence a new DT compatible value must be used to describe the HW. This
patch updates the driver to support that new compatible value.

That said, the HW differences are only relevant when enabling certain
high-performance transfer modes. Since the driver is currently very
simple and doesn't enable those modes, we don't actually need to address
any of these HW differences in the code yet, hence the simple nature of
this patch.

5d60e50054 mmc: tmio: add new TMIO_MMC_HAVE_HIGH_REG flags
The accessibility checking method to the higher register was added by
69d1fe18e9 (mmc: tmio: only access registers above 0xff, if available)
But, it doesn't care 32bit register.  It is impossible to calculate it
from the resource size, since there is 16/32 bit register IP (e.g. VERSION
is located on 0xe2 if 16bit register, but it is located on 0x1c4 if 32bit
register).

This patch adds new TMIO_MMC_HAVE_HIGH_REG flags, tmio_mmc driver has it,
and sh_mobile_sdhi doesn't have it today.

05fae4a755 mmc: tmio: use -EPROBE_DEFER if driver can't find regulator
Current tmio driver tries to use default ocr_avail if 1) it couldn't
find regulator and 2) if platform data doesn't have ocr_mask.
But, there is no guarantee that regulator driver probe is faster than
TMIO driver probe.  TMIO driver will not use regulator in such case.

By this patch, TMIO driver returns -EPROBE_DEFER if it couldn't find
regulator and if platform doesn't have ocr_mask.  Because, there is a
possibility that regulator has not been probed, but the user expects it.

This patch changes tmio_mmc_host_probe() behavior, but there is no user
who has conflict.

	spin_unlock_irqrestore(&host->lock, flags);

<=== Here it is possible one pending finish_tasklet get running
     and it will operate the original mrq, and notified the mrq

	sdhci_execute_tuning(mmc, tuning_opcode);
	spin_lock_irqsave(&host->lock, flags);
	host->mrq = mrq;
...
}

In the above race place, the original mrq should not be finished wrongly,
so here before unlock the spinlock, we need to set the host->mrq to NULL
to avoid this case.

ce090a4eb9 mmc: sdhci-esdhc-imx: fix runtime pm unbalance issue
Since we're using common esdhc_send_command for tuning commands and
the core code will call pm_runtime_put after command is finished.
So we add a pm_runtime_get_sync here to get the balance.

8b2bb0adce mmc: esdhc-imx: clearing SDHCI_CTRL_EXEC_TUNING should not affect other bits
Current code will clear all turning related bits like ESDHC_STD_TUNING_EN
and ESDHC_MIX_CTRL_FBCLK_SEL when clear SDHCI_CTRL_EXEC_TUNING.
This may cause the card which has already passed the turning to become
unwork since the turning status lost.
We observed this failure when enable runtime pm.

BTW, imx needs to enable ESDHC_MIX_CTRL_FBCLK_SEL bit for turned clock.
The FBCLK_SEL will be cleared when SDHCI_CTRL_TUNED_CLK is cleared
and SDHCI_CTRL_EXEC_TUNING is not set.
This is used in case we change to another normal card from a UHS card
in the same slot. FBCLK_SEL is not needed for normal card.

After that, SDHCI_CTRL_EXEC_TUNING will only affect ESDHC_MIX_CTRL_EXE_TUNE.
Clearing it does not affect the turned card to remain working on UHS mode.

83cc16d767 mmc: core: mmc DDR mode should not depend on UHS_DDR50
The MMC_CAP_UHS_DDR50 must work on 1.8v.
However, the eMMC DDR mode can work on either 1.8v or 3.3v and
should not depend on UHS_DDR50.
So get rid of this limitation to let controller without 1.8v
signal voltage support can also work for eMMC DDR mode if it claims.

0e4b0743bb ARM: SoC fixes for 3.13-rc
Mostly bugfixes and a few small code removals. Worth pointing out is:
 
 - A handful of more fixes to get DT enablement working properly on OMAP,
   finding new breakage of things that don't work quite right yet without
   the traditional board files. I expect a bit more of this to come in this
   release as people test on their hardware.
 - Implementation of power_down_finish() on vexpress, to make kexec work and
   to stop the MCPM core to produce a warning (the warning was new to 3.13-rc1).
 - A handful of minor fixes for various platforms.
