0f6e73d0ab mmc: dw_mmc: Add MSHC compatible for Exynos4412
This patch adds the compatible string for MSHC controller of Exynos4412.
And exynos5250_dwmmc_caps is renamed to exynos_dwmmc_caps, since it has the
capabilities of common features supported by Exynos4 and Exynos5.

cfbeb59c7a mmc: dw_mmc: Handle unaligned data submission correctly
Commit f9c2a0dc42
"mmc: dw_mmc: Fix PIO mode with support of highmem" introduced
a regression since v3.2 making the mmc_test hang on test #13
with a "Data starvation by host timeout" interrupt.

This is because, sg_mapping_iter is used to iterate through the
data which spans on multiple pages. The problem is detected on
unaligned data submission where the code previously checked for
!(sg_next(host->sg)) which is true because we only have a single
scatter/gather list which then expands to multiple pages.
Therefore, the driver incorrectly assumed that this was the last
list item and submitted unaligned data to the mmc device. This
overflowed the FIFO on the device before all the data were written
to it. The code was fixed to only submit unaligned data when we are
handling the last sg_miter item by checking whether we reached
the desired data length or not.

The patch was tested against mmc_test and all the tests passed.

There is no reason to loop when handling an interrupt. The "if" clauses

e6f34e2fd3 mmc: dw_mmc: setpower on MMC_POWER_{UP,OFF}
Call the setpower platform callback in response to set_ios with
ios->power_mode == MMC_POWER_UP or MMC_POWER_OFF, instead of from the

This appears to fix a problem I have where a card stuck in a funny state
doesn't get properly cleared by the power being turned off, presumably
due to lack of power sequencing. This resulted in the following log

1450734ec6 mmc: core: enhance card removal judgement for slow removal
Function _mmc_detect_card_removed will be called to know whether
the card is still present when host->bus_ops->detect is called.
In current code, the return value of this function generally only
depend on the result of sending cmd13 to card, which may not safe
for card with detection support like slot gpio detection.
Because the communication status between host and card may out of
sync with the detect status if remove the card slowly or hands shake
during the process. The direct reason is the async between card
detect switch and card/slot pad contaction in hardware, which is
defined by spec.

The spec define card insert/remove sequence as below (both standard size
SD card and MicroSD card have the same sequence):
"Part 1 Standard Size SD Card Mechanical Addendum Ver4.00 Final,
Appendix C: Card Detection Switch" (Take normally open type as example)
a)SD card insertion sequence:
  The card detection switch should be turned on after all SD card
  contact pads are connected to the host connector contact pads.
b)SD removal sequence:
  The card detection switch should be turned off when the SD card
  is just going to be removed and before any SD card contact pad is
  disconnected from the host connector contact pad.

Below is the sequence when this issue occur (Take slot gpio detection
as example and remove the card slowly during the process):
1. gpio level changed and card detect interrupt triggered.
2. mmc_rescan was launched.
3. the card pads were still contacted with the slot pads because of slow
   removal. So _mmc_detect_card_removed and mmc_rescan think card was
   still present (cmd13 succeed).
4. card pads were discontacted from the card slot pads.
So the card was actually removed finally but the card removal event
has been missed by system.
The interval length between step 1 and step 4 depends on the
card removal speed. If it's longer than the detect work schedule
delay which is 200ms, this issue will likely happen.

This patch add the card detect status check in function
_mmc_detect_card_removed if cmd13 check succeed and host->ops->get_cd
provided. If get_cd detect no card present then schedule another detect
work 200ms later.

  Only the fbdev/framebuffer piece remains now that the SCSI stuff has
  gone in.

  Here are the UAPI disintegration bits for the fbdev drivers.  It
  appears that Florian hasn't had time to deal with my patch, but back
  in December he did say he didn't mind if I pushed it forward."

Yay.  No more uapi movement.  And hopefully no more big header file
cleanups coming up either, it just tends to be very painful.
