as shown in the following patches. So a separate file for

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.

We have a number of front-end drivers for SDHCI_PLTFM, some of them
use 'select MMC_SDHCI_PLTFM', others use 'depends on'. This is
inconsistent and confusing, and in one case has also led to a
build error because of incomplete dependencies:
warning: (MMC_SDHCI_PXAV3 && MMC_SDHCI_PXAV2 && MMC_SDHCI_BCM_KONA) selects MMC_SDHCI_PLTFM which has unmet direct dependencies (MMC && MMC_SDHCI)

The MMC host driver should not select the pmic driver, since that
may have other dependencies, notably i2c in this case. It's not
clear what the exact requirement of the driver is, but to preserve
the behavior, this patch changes the 'select' into 'depends on',
meaning you now have to turn on TPS65010 explicitly and then
MMC_OMAP.

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.

Here is the "big" char/misc driver patches for 3.8-rc1. I'm starting to
put random driver subsystems that I had previously sent you through the
driver-core tree in this tree, as it makes more sense to do so.
Nothing major here, the various __dev* removals, some mei driver
updates, and other random driver-specific things from the different
maintainers and developers.
Note, some MFD drivers got added through this tree, and they are also
coming in through the "real" MFD tree as well, due to some major
mis-communication between me and the different developers. If you have
any merge conflicts, take the ones from the MFD tree, not these ones,
sorry about that.
All of this has been in linux-next for a while.
