a23f7dc82d davinci: Fix watchdog reset code
The davinci reset routine, davinci_watchdog_reset(), sets the
TCR register instead of the TGCR register as it should to put
the WDT into its "Initial State".

It also writes the WDTCR register without the proper WDKEY
which is pointless since the register will be write-protected.

60902a2cb1 davinci: EDMA: multiple CCs, channel mapping and API changes
- restructure to support multiple channel controllers by using
  additional struct resources for each CC

- interface changes visible to EDMA clients

  Introduce macros to build IDs from controller and channel number,
  and to extract them. Modify the edma_alloc_slot function to take an
  extra argument for the controller.

  Also update ASoC drivers to use API.  ASoC changes
  Acked-by: Mark Brown <broonie@opensource.wolfsonmicro.com>

- Move queue related mappings to dm<soc>.c

  EDMA in DM355 and DM644x has two transfer controllers while DM646x
  has four transfer controllers. Moving the queue to tc mapping and
  queue priority mapping to dm<soc>.c will be helpful to probe these
  mappings from platform device so that the machine_is_* testing will
  be avoided.

- add channel mapping logic

  Channel mapping logic is introduced in dm646x EDMA. This implies
  that there is no fixed association for a channel number to a
  parameter entry number. In other words, using the DMA channel
  mapping registers (DCHMAPn), a PaRAM entry can be mapped to any
  channel. While in the case of dm644x and dm355 there is a fixed
  mapping between the EDMA channel and Param entry number.

dde5828f56 ARM: Fix broken highmem support
Currently, highmem is selectable, and you can request an increased
vmalloc area.  However, none of this has any effect on the memory
layout since a patch in the highmem series was accidentally dropped.
Moreover, even if you did want highmem, all memory would still be
registered as lowmem, possibly resulting in overflow of the available
virtual mapping space.

The highmem boundary is determined by the highest allowed beginning
of the vmalloc area, which depends on its configurable minimum size
(see commit 60296c71f6 for details on
this).

We should create mappings and initialize bootmem only for low memory,
while the zone allocator must still be told about highmem.

Currently, memory nodes which are completely located in high memory
are not supported.  This is not a huge limitation since systems
relying on highmem support are unlikely to have discontiguous memory
with large holes.

[ A similar patch was meant to be merged before commit 5f0fbf9eca
  and be available  in Linux v2.6.30, however some git rebase screw-up
  of mine dropped the first commit of the series, and that goofage
  escaped testing somehow as well. -- Nico ]

dee2b904a1 IXP4xx: Fix IO_SPACE_LIMIT for 2.6.31-rc core PCI changes
2.6.31-rc kernels don't boot on my ixp4xx box (ds101), because the libata
driver doesn't find the PCI IDE controller any more. 2.6.30 was fine.
I traced this to a PCI update (1f82de10d6)
in 2.6.30-git19. Diffing the kernel boot logs from 2.6.30-git18 and
2.6.30-git19 illustrates the breakage:

Every arch except arm's ixp4xx defines IO_SPACE_LIMIT as an all-bits-one
bitmask, typically -1UL but sometimes only a 16-bit 0x0000ffff. But ixp4xx
defines it as 0xffff0000, which is now causing the PCI failures.

Russell King noted that ixp4xx has 64KB PCI IO space, so IO_SPACE_LIMIT
should be 0x0000ffff. This patch makes that change, which fixes the PCI
failures on my ixp4xx box.

Stop referencing CLOCK_TICK_RATE in the KS8695 drivers, rather refer
to a KS8695_CLOCK_RATE.

55b6019ae2 OMAP: GPIO: clear/restore level/edge detect settings on mask/unmask
If IRQ triggering is enabled, it can trigger a pending interrupt
even for masked interrupts.  Any pending GPIO interrupts can
prevent the powerdomain from hitting retention.

Problem found, reported and additional review and testing by Chunquiu
Wang.

Use the min/max settings from CPUfreq policy rather than
processor defined min/max settings.

Without this patch, it's possible to scale frequency outside
the current policy range.

bcf396c480 OMAP2/3/4: UART: allow in-order port traversal
Use list_add_tail() when adding discovered UART ports.  This is so
traversal using list_for_each_entry() will traverse the list in the

fd455ea899 OMAP2/3/4: UART: Allow per-UART disabling wakeup for serial ports
This patch causes the OMAP uarts to honor the sysfs power/wakeup file
for IOPAD wakeups. Before the OMAP was always woken up from off mode
on a rs232 signal change.  This patch also creates a different
platform device for each serial port so that the wakeup properties can
be control per port.

By default, IOPAD wakeups are enabled for each UART.  To disable,

  # echo disabled > /sys/devices/platform/serial8250.0/power/wakeup

Where serial8250.0 can be replaced by .1, or .2 to control the other
ports.

Original idea and original patch from Russ Dill <russ.dill@gmail.com>

2466211e5d OMAP3: Fixed crash bug with serial + suspend
It was possible for an unhandled interrupt to occur if there was incoming
serial traffic during wakeup from suspend. This was caused by the code
in arch-arm/mach-omap2/serial.c keeping interrupt enabled all the time,
but not acking its interrupts. Applies on top of PM branch.

Use the PM begin/end hooks to ensure that the "serial idle" interrupts
are disabled during the suspend path.  Also, since begin/end hooks are
now used, use the suspend_state that is passed in the begin hook instead
of the enter hook as per the platform_suspend_ops docs.
