Guennadi Liakhovetski 162f43e31c mmc: tmio: fix a deadlock
Currently the tmio-mmc driver contains a recursive runtime PM method
invocation, which leads to a deadlock on a mutex. Avoid it by taking
care not to request DMA too early.

Guennadi Liakhovetski 332bdb506f mmc: tmio: fix a recently introduced bug in DMA code
A recent commit "mmc: tmio: Share register access functions" has swapped
arguments of a macro and broken DMA with TMIO MMC. This patch fixes the
arguments back.

Simon Horman a11862d338 mmc: tmio: Share register access functions
Move register access functions into a shared header.
Use sd_ctrl_write16 in tmio_mmc_dma.c:tmio_mmc_enable_dma().

Other than avoiding (trivial) open-coding, the motivation for
this is to allow platform-hooks in access functions to
be applied across all applicable accesses.

Simon Horman 95c7348d94 mmc: tmio: name 0xd8 as CTL_DMA_ENABLE
This reflects at least the current usage of this register
and I think it improves the readability of the code ever so slightly.

Alexey Dobriyan b7f080cfe2 net: remove mm.h inclusion from netdevice.h
Remove linux/mm.h inclusion from netdevice.h -- it's unused (I've checked manually).

To prevent mm.h inclusion via other channels also extract "enum dma_data_direction"
definition into separate header. This tiny piece is what gluing netdevice.h with mm.h
via "netdevice.h => dmaengine.h => dma-mapping.h => scatterlist.h => mm.h".
Removal of mm.h from scatterlist.h was tried and was found not feasible
on most archs, so the link was cutoff earlier.

Hope people are OK with tiny include file.

Note, that mm_types.h is still dragged in, but it is a separate story.

Guennadi Liakhovetski e6ee7182c3 mmc: Add runtime and system-wide PM to the TMIO MMC driver
Add runtime and system-wide power management to the TMIO MMC driver
in PIO and DMA modes, allowing it to properly save and restore its
state during system suspend. Runtime PM is very crude ATM, because
the controller has to be powered on all the time to detect card
hotplug events.

Simon Horman cba179aec7 mmc: tmio_mmc: Move some defines into a shared header
Also add TMIO_BBS.

This allows these defines to also be used by zboot.

Guennadi Liakhovetski b6147490e6 mmc: tmio: split core functionality, DMA and MFD glue
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.
