The card is not always clocked and the clock frequency zero is perfectly
legal, thus this code in mmc_set_data_timeout() may cause a division by
zero. It will be triggered more often if you're using software clock
gating but can be triggered under other conditions too.

With current code card insert/eject interrupts will acknowledge outstanding
commands. Normally this seems to be no problem, however if the hardware gets
stuck and no interrupts for CMD_TIMEOUT or CMD_RESPEND are generated, then
inserting and ejecting cards will falsely acknowledge outstanding commands
from the core.
This patch changes the behavior so that CMDs are only acked, if
CMD_TIMEOUT or CMD_RESPEND is received.

For example, with SDIO WLAN cards, some transfers happen with buffers at
odd addresses, whereas the SH-Mobile DMA engine requires even addresses
for SDHI. This patch extends the tmio driver with a bounce buffer, that
is used for single entry scatter-gather lists both for sending and
receiving. If we ever encounter unaligned transfers with multi-element
sg lists, this patch will have to be extended. For now it just falls
back to PIO in this and other unsupported cases.

The easiest way to fall back to PIO, when a DMA descriptor allocation
fails is to disable DMA on the controller but continue with the current
request in PIO mode. This way tmio_mmc_start_dma() can become void, since
it cannot be failing any more. The current version is also broken: it is
testing a wrong pointer and thus failing to recognise, that a descriptor
allocation wasn't successful.

Rewrite and clean up mmc_rescan() to properly retry frequencies lower
than 400kHz. Failures can happen both in sd_send_* calls and
mmc_attach_*. Break out "mmc_rescan_try_freq" from the frequency
selection loop. Symmetrize claim/release logic in mmc_attach_* API,
and move the sd_send_* calls there to make mmc_rescan easier to read.

This patch supports controllers with no internal clock divider in SDHCI,
such as the s5pc210 board. The external clock divider can be used to
make a proper clock because SDHCI doesn't support internal clock divider
by itself.
If external clock divider type is selected, some functions related
to clock control will be overrided by other functions.
The current clock control index is added to let you know which
clock bus is used for SDHCI when overriding functions.
Checking functions are added into sdhci_s3c_consider_clock, because
the clock divider step is different from that of host controller.

Upon system resume, SDIO core must reinitialize cards that were
powered off during suspend.
If the card had its power kept during suspend (and thus it is
'powered-resumed'), SDIO core performs only a limited reinitializing,
mainly needed to make sure that the card wasn't removed/replaced.
If a __nonremovable__ card is powered-resumed, we can safely skip the
reinitializing phase.
Note: 9b966aa (mmc: sdio: fully reconfigure oldcard on resume) removed
the bus width reconfiguration since mmc_sdio_init_card already does it.
It is brought back now in case mmc_sdio_init_card is skipped.

Initial SDIO runtime PM implementation took a conservative approach
of powering up cards (and fully reinitializing them) on system suspend,
just before the suspend handlers of the relevant drivers were executed.
To avoid redundant power and reinitialization cycles, this patch removes
this behavior: if a card is already powered off when system suspend kicks
in, it is left at that state.
If a card is active when a system sleep starts, everything is
straightforward and works exactly like before. But if the card was
already suspended before the sleep began, then when the MMC core powers
it back up on resume, its run-time PM status has to be updated to reflect
the actual post-system sleep status.
The technique to do that is borrowed from the I2C runtime PM
implementation (for more info see Documentation/power/runtime_pm.txt).

mmc_rescan() checks whether registered cards are still present before
skipping them, by calling the bus-specific ->detect() handler.
With buses that support runtime PM, the card may be powered off at
this point, so they need to be powered on and fully reinitialized before
->detect() executes.
This whole process is redundant with nonremovable cards; in those cases,
we can safely skip calling ->detect() and implicitly assume its success.

JMicron 388 SD/MMC combo controller supports the 1.8V low-voltage for
SD, but MMC doesn't work with the low-voltage, resulting in an error
at probing.
This patch adds the support for multiple voltage mask per device type,
so that SD works with 1.8V while MMC forces 3.3V. Here new ocr_avail_*
fields for each device are introduced, so that the actual OCR mask is
switched dynamically.
Also, the restriction of low-voltage in core/sd.c is removed when the
bit is allowed explicitly via ocr_avail_sd mask.
This patch was rewritten from scratch based on Aries' original code.

This patch modifies the MMC core code to optionally call the set_ios()
operation on the driver with the clock frequency set to 0 (gate) after
a grace period of at least 8 MCLK cycles, then restore it (ungate)
before any new request. This gives the driver the option to shut down
the MCI clock to the MMC/SD card when the clock frequency is 0, i.e.
the core has stated that the MCI clock does not need to be generated.
It is inspired by existing clock gating code found in the OMAP and
Atmel drivers and brings this up to the host abstraction. Gating is
performed before and after any MMC request.
This patchset implements this for the MMCI/PL180 MMC/SD host controller,
but it should be simple to switch OMAP/Atmel over to using this instead.
mmc_set_{gated,ungated}() add variable protection to the state holders
for the clock gating code. This is particularly important when ordinary
.set_ios() calls would race with the .set_ios() call resulting from a
delayed gate operation.

Simplify the driver by removing the possibility to build it without the DMA
support and remove the respective Kconfig parameter.

Fixes for sdhci-of and ipmi drivers.
Auditing all drivers using of_get_property did not find other
occurrences likely to be used on LE platforms.

Some OF drivers could likely be used on non-powerpc OF based platforms,
so fix the kconfig depends to be CONFIG_OF instead of CONFIG_PPC_OF.
Compile tested on ARM and sparc.

Make the MMCI announcement printk say which primecell part number
has been found. Display the revision as an unsigned decimal, and
display only the first 8 hex digits of the base address unless it's
larger.

Workqueue creation API has been updated and flush_scheduled_work() is
deprecated and scheduled to be removed.
* core/core.c: Use alloc_ordered_workqueue() instead of
create_singlethread_workqueue(). This removes an unnecessary
rescuer.
* host/omap.c: Create, use and flush mmc_omap_wq instead of the
system_wq.
* Flush host->mmc_carddetect_work directly on removal instead of using
flush_scheduled_work().

In the error-path where PM notifies PM_POST_RESTORE, the rescan-blockage
should be cleared as well. Otherwise it'll be never re-probed.
Also, as a bonus, this fixes a bug in S4 with user-mode suspend in the
current code, as it sends PM_POST_RESTORE instead of
PM_POST_HIBERNATION wrongly.
