  mmc: moxart: fix handling of sgm->consumed, otherwise WARN_ON triggers
  mmc: sdhci-of-dwcmshc: th1520: Increase tuning loop count to 128
  mmc: sdhci-msm: pervent access to suspended controller

When e.g. 8 bytes are to be read, sgm->consumed equals 8 immediately after
sg_miter_next() call. The driver then increments it as bytes are read,
so sgm->consumed becomes 16 and this warning triggers in sg_miter_stop():
WARN_ON(miter->consumed > miter->length);

This patch adds initial zeroing of sgm->consumed. It is then incremented

Fix SD card tuning error by increasing tuning loop count
from 40(MAX_TUNING_LOOP) to 128.

For some reason the tuning algorithm requires to move through all the taps
of delay line even if the THRESHOLD_MODE (bit 2 in AT_CTRL_R) is used
instead of the LARGEST_WIN_MODE.

Generic sdhci code registers LED device and uses host->runtime_suspended
flag to protect access to it. The sdhci-msm driver doesn't set this flag,
which causes a crash when LED is accessed while controller is runtime
suspended. Fix this by setting the flag correctly.

"PM runtime functions" was been added in sdhci-omap driver in commit
f433e8aac6b9 ("mmc: sdhci-omap: Implement PM runtime functions") along
with "card power off and enable aggressive PM" in commit 3edf588e7fe0
("mmc: sdhci-omap: Allow SDIO card power off and enable aggressive PM").

Since then, the sdhci-omap driver doesn't work using mmc-hs200 mode
due to the tuning values being lost during a pm transition.

As for the sdhci_am654 driver, request a new tuning sequence before
suspend (sdhci_omap_runtime_suspend()), otherwise the device will
trigger cache flush error:

  mmc1: cache flush error -110 (ETIMEDOUT)
  mmc1: error -110 doing aggressive suspend

followed by I/O errors produced by fdisk -l /dev/mmcblk1boot1:

  I/O error, dev mmcblk1boot0, sector 64384 op 0x0:(READ) flags 0x80700 phys_seg 1
  prio class 2
  I/O error, dev mmcblk1boot1, sector 64384 op 0x0:(READ) flags 0x80700 phys_seg 1

Don't re-tune if auto retuning is supported in HW (when SDHCI_TUNING_MODE_3
is available).

Pull spi updates from Mark Brown:
 "This release sees some exciting changes from David Lechner which
  implements some optimisations that have been talked about for a long
  time which allows client drivers to pre-prepare SPI messages for
  repeated or low latency use. This lets us move work out of latency
  sensitive paths and avoid repeating work for frequently performed
  operations. As well as being useful in itself this will also be used
  in future to allow controllers to directly trigger SPI operations (eg,
  from interrupts).

  Otherwise this release has mostly been focused on cleanups, plus a
  couple of new devices:

   - Support for pre-optimising messages

   - A big set of updates from Uwe Kleine-König moving drivers to use
     APIs with more modern terminology for controllers

   - Major overhaul of the s3c64xx driver

   - Support for Google GS101 and Samsung Exynos850"
