SDIO IRQs got unmasked on sh-mobile while writing to the
CTL_CLK_AND_WAIT_CTL register, because that register at address 0x138
is not implemented on those SoCs and writes to it overwrite the
register at address 0x38: CTL_SDIO_IRQ_MASK. Previous patches
eliminated access to register above 0xff on sh-mobile, so that this
work-around isn't needed anymore.Signed-off-by: Guennadi Liakhovetski

Not all tmio implementations have registers above oxff. Accessing

On sh-mobile platforms the SDHI driver was using the tmio_mmc SD/SDIO
MFD cell driver. Now that the tmio_mmc driver has been split into a
core and a separate MFD glue, we can support SDHI natively without the
need to emulate an MFD controller. This also allows to support systems
with an on-SoC SDHI controller and a separate MFD with a TMIO core.Signed-off-by: Guennadi Liakhovetski

TMIO MMC chips contain an SD / SDIO IP core from Panasonic, similar to
the one, used in MN5774 and other MN57xx controllers. These IP cores are
included in many multifunction devices, in sh-mobile chips from Renesas,
in the latter case they can also use DMA. Some sh-mobile implementations
also have some other specialities, that MFD-based solutions don't have.
This makes supporting all these features in a monolithic driver inconveniet
and error-prone. This patch splits the driver into 3 parts: the core,
the MFD glue and the DMA support. In case of a modular build, two modules
will be built: mmc_tmio_core and mmc_tmio.Signed-off-by: Guennadi Liakhovetski

This patch allows transferring of some requests in PIO and some in DMA
mode and defaults to using DMA only for transfers longer than 8 bytes.
This is especially useful with SDIO, which can have lots of 2- and 4-byte
transfers, creating unnecessary high overhead, when executed in DMA.Signed-off-by: Guennadi Liakhovetski

Fix the NO INT in the Multi-BLK IO in SD/MMC, and Multi-BLK read in
SDIO on imx53.The CMDTYPE of the CMD register (offset 0xE) should be set to "11"
when the STOP CMD12 is issued on imx53 to abort one open ended
multi-blk IO. Otherwise the TC INT wouldn't be generated.In exact block transfer, the controller doesn't complete the
operations automatically as required at the end of the transfer
and remains on hold if the abort command is not sent on imx53.As a result, the TC flag is not asserted and SW receives timeout
exception. Set bit1 of Vendor Spec register to fix it.Signed-off-by: Richard Zhu

This patch is related to re-init processing on suspend/resume.

maybe controller should be rescan for card. But if assume card is
non-removable, need to restore the old value at registers.We store the value of FIFOTH at probe time and then restore it in
