8b1935e6a3 dmaengine: shdma: separate DMA headers.
Separate SH DMA headers into ones, commonly used by both drivers, and ones,
specific to each of them. This will make the future development of the
dmaengine driver easier.

027811b9b8 dmaengine: shdma: convert to platform device resources
The shdma dmaengine driver currently uses numerous macros to support various
platforms, selected by ifdef's. Convert it to use platform device resources and
lists of channel descriptors to specify register locations, interrupt numbers
and other system-specific configuration variants. Unavoidably, we have to
simultaneously convert all shdma users to provide those resources.

47a4dc26ee dmaengine: shdma: fix DMA error handling.
Present DMA error ISR in shdma.c is bogus, it locks the system hard in multiple
ways. Fix it to abort all queued transactions on all channels on the affected
controller and giving submitters a chance to get a DMA_ERROR status for aborted
transactions. Afterwards further functionality is again possible without the
need to re-load the driver.

a55ab496ea sata_via: Delay on vt6420 when starting ATAPI DMA write
When writing a disc on certain lite-on dvd-writers (also rebadged
as optiarc/LG/...) connected to a vt6420, the ATAPI CDB ends
up in the datastream and on the disc, causing silent corruption.
Delaying between sending the CDB and starting DMA seems to
prevent this.

I do not know if there are burners that do not suffer from
this, but the patch should be safe for those as well.

There are many reports of this issue, but AFAICT no solution was
found before. For example:

4b7d1c0509 ata: Detect Delkin Devices compact flash
I have a Delkin Devices compact flash card that isn't being recognized using the
SATA/PATA drivers.
The card is recognized and works with the deprecated ATA drivers.

The error I am seeing is:
ata1.00: failed to IDENTIFY (device reports invalid type, err_mask=0x0)

I tracked it down to ata_id_is_cfa() in include/linux/ata.h.
The Delkin card has id[0] set to 0x844a and id[83] set to 0.
This isn't what the kernel expects and is probably incorrect.

The simplest work-around is to add a check for 0x844a to ata_id_is_cfa().

02d1d6160f sata_via: Correctly setup PIO/DMA for pata slave on vt6421.
Before only the timings for master were set. Datasheet can be found
here: ftp://ftp.vtbridge.org/Docs/Storage/DS_VT6421A_100_CCPL.PDF
Surprisingly, a slave drive works without this patch. According to the
datasheet, the controller by default derives the DMA mode from the
Set Features command issued to a drive. Not sure about the PIO
timings, though. The real problem is that the timings for the master
effectively are the ones tuned for the slave. If these support
different UDMA-settings, there is trouble, especially when the slave
supports a higher UDMA than the master.

Anyhow, using the same mechanism for both master and slave seems like
a good idea.

27943620cb libata: implement spurious irq handling for SFF and apply it to piix
Traditional IDE interface sucks in that it doesn't have a reliable IRQ
pending bit, so if the controller raises IRQ while the driver is
expecting it not to, the IRQ won't be cleared and eventually the IRQ
line will be killed by interrupt subsystem.  Some controllers have
non-standard mechanism to indicate IRQ pending so that this condition
can be detected and worked around.

This patch adds an optional operation ->sff_irq_check() which will be
called for each port from the ata_sff_interrupt() if an unexpected
interrupt is received.  If the operation returns %true,
->sff_check_status() and ->sff_irq_clear() will be cleared for the
port.  Note that this doesn't mark the interrupt as handled so it
won't prevent IRQ subsystem from killing the IRQ if this mechanism
fails to clear the spurious IRQ.

This patch also implements ->sff_irq_check() for ata_piix.  Note that
this adds slight overhead to shared IRQ operation as IRQs which are
destined for other controllers will trigger extra register accesses to
check whether IDE interrupt is pending but this solves rare screaming
IRQ cases and for some curious reason also helps weird BIOS related
glitch on Samsung n130 as reported in bko#14314.

  http://bugzilla.kernel.org/show_bug.cgi?id=14314

* piix_base_ops dropped as suggested by Sergei.

* Spurious IRQ detection doesn't kick in anymore if polling qc is in
  progress.  This provides less protection but some controllers have
  possible data corruption issues if the wrong register is accessed
  while a command is in progress.

6066193399 pata_hpt3x2n: always stretch UltraDMA timing
The UltraDMA Tss timing must be stretched with ATA clock of 66 MHz, but the
driver only does this when PCI clock is 66 MHz, whereas it always programs
DPLL clock (which is used as the ATA clock) to 66 MHz.
