Pierre Ossman 0b82684c3c sdhci: improve no card, no reset quirk
The quirk was meant to just inhibit some resets, but ended up blocking
all of them. Fortunately, this was just what was needed. Change the
comment to reflect reality.

Also, this issue has just been observed on Samsung laptops, so reduce
the number of chips the quirk affects.

Jarkko Lavinen 9d7c6eee52 MMC: OMAP: Do not busy wait for end of command for ever
The limit was a fixed 100k limit in the busy loop, which is not
accurate. It would better to have time limit for the worst case
which occurs when sending 80 cycles at 400 kHz and takes about
200 microseconds, so limit the max time spend in the busy loop
for some 250 microseconds.

Use work queues for starting new commands instead of starting them
directly from irq handler. The command scheduling needs to be delayed

Jarkko Lavinen 7584d276d4 MMC: OMAP: Use tasklet instead of workqueue for cover switch notification
The cover waitqueue is occasionally scheduled twice from timer

This path also adds some cleanups.

Jarkko Lavinen eb1860bccd MMC: OMAP: Abort stuck commands
When a card is removed while it is being accessed, a command can get stuck so
that no timeout or end of command interrupt ever occurs. The command getting
stuck is almost always CDM12, but also the other commands can get stuck. Catch
a stuck command with a timer and try sending the initialization stream until
the controller starts running again and responds with the end of command
status.

David Brownell 6e996ee8e7 at91_mci: use generic GPIO calls
Update the AT91 MMC driver to use the generic GPIO calls instead of the
AT91-specific calls; and to request (and release) those GPIO signals.

That required updating the probe() fault cleanup codepaths.  Now there
is a single sequence for freeing resources, in reverse order of their
allocation.  Also that code uses use dev_*() for messaging, and has less
abuse of KERN_ERR.

Likewise with updating remove() cleanup.  This had to free the GPIOs,
and while adding that code I noticed and fixed two other problems:  it
was poking at a workqueue owned by the mmc core; and in one (rare)
case would try freeing an IRQ that it didn't allocate.

  58b053e4ce ("Update arch/ to use sg helpers")
  45711f1af6 ("[SG] Update drivers to use sg helpers")
  fa05f1286b ("Update net/ to use sg helpers")

converted many files to use the scatter gather helpers without ensuring
that the necessary headerfile <linux/scatterlist> is included.  This
happened to work for ia64, powerpc, sparc64 and x86 because they
happened to drag in that file via their <asm/dma-mapping.h>.

On most of the others this probably broke.

Instead of increasing the header file spider web I choose to include
<linux/scatterlist.h> directly into the affectes files.

Andrew Victor 9e3866b548 mmc: at91_mci: cleanup: use MCI_ERRORS
A small MMC driver cleanup.

Use the defined AT91_MCI_ERRORS in at91_mci_completed_command() instead
of specifying all the error bits individually.
