5947c167d1 mfd: rtsx: Add shutdown callback in rtsx_pci_driver
Some actions to clear power state should be handled in .shutdown
callback in rtsx_pci_driver. This patch adopts the following measures to
catch this goal:
1. Add a function rtsx_pci_power_off to abstract the common ops in
.shutdown and .suspend
2. Add pcr->ops->force_power_down to fulfill the individual action for
each reader model

b32408f644 mfd: twl6030-irq: Convert to use linear irq_domain
Since the TWL6030 PMIC is used with OMAP4 SoCs only and OMAP4 legacy
boot is dropped there are no needs to allocate the range of IRQ
descriptors during system boot to support TWL6030 IRQs.

Hence, convert it to use linear irq_domain and move IRQ configuration in
.map()/.unmap() callbacks of irq_domain. So, IRQ mapping and descriptors
allocation will be performed dynamically basing on DT configuration.

The error message will be reported in case if unmapped IRQ is received by
TWL6030 (virq==0).

87343e5341 mfd: twl6030-irq: Migrate to IRQ threaded handler
1) Removed request_irq() and replaced it with request_threaded_irq().

2) Removed generic_handle_irq() and replaced it with
handle_nested_irq().
  Handling of these interrupts is nested, as we are handling an
interrupt (for e.g rtc, mmc1) when we are still servicing TWL irq.

3) Removed I2C read-retry logic for the case when twl_i2c_read() is
failed inside IRQ handler - there is no sense to do that, so just report
an error and return.

4) Each nested IRQ is configured with corresponding parent_irq,
which need to be retriggered in case if nested IRQ is marked
as IRQS_PENDING.

The present code had a check, which returned error if the frequency

Now the code just uses the internal ADC clock divider to set the ADC
frequency w.r.t the sys clock.

4b3b4a501d mfd: Fix for DA9055 driver initialization
This patch clears all the events received while powering up DA9055.

While powering up DA9055, both power sequencer and gpio events are received.
These events remain uncleared after boot up, due to which further event handling
also fails. DA9055 has three event registers. The event register bits are set
to '1' on receiving an event. The events can be cleared on writing a '1' to
the set bit, which would then clear that bit to '0'. After applying this patch
we have a clean state after boot up.

Pull qxl drm fixes from Dave Airlie:
 "Okay as I warned, the qxl driver was running a bit free and loose with
  its ttm object reservations and the new lockdep enabled reservation
  tracking shone a bright light into it, it also with the new
  reservations mutexes hits a possible deadlock during boot.

  The first patch is a real fix to render the console correctly as the
  driver used to just drop irq renderering as too hard, this also fixes
  a sleeping while atomic warning.

  The other two patches are the big ugly ones that redo how the driver
  allocates objects and reserves them and makes things all work
  properly, I've tested this in a VM, and compared to the current code
  which hits a lockdep warning and the sleep while atomic warning before
  failing.

  So sorry this is coming in late, I should have tested qxl before
  merging the mutex code, but I'd rather just fix qxl with this than
  revert the reservations code at this point"

* 'qxl-fixes' of git://people.freedesktop.org/~airlied/linux:

fef36a7a31 ARM: SoC fixes for 3.11-rc
This is a largeish batch of fixes, mostly because I missed -rc2 due to
 travel/vacation. So in number these are a bit more than ideal unless
 you amortize them over two -rcs.
 
 Quick breakdown:
  - Defconfig updates
    - Making multi_v7_defconfig useful on more hardware to encourage
      single-image usage
    - Davinci and nomadik updates due to new code merged this merge window
  - Fixes for UART on Samsung platforms, both PM and clock-related
  - A handful of warning fixes from defconfig builds, including for
    max8925 backlight and pxamci (both with appropriate acks)
  - Exynos5440 fixes for LPAE configuration, PM
  - ...plus a bunch of other smaller changes all over the place
 
 I expect to switch to regressions-or-severe-bugs-only fixes from here
 on out.

Pull libata fixes from Tejun Heo:
 "Assorted libata updates.

  The most critical one is a fix for ahci oops during boot.  Also, a new
  smallish platform ahci driver is added and sata_inic162x is marked
  clearly as experimental (it whines during boot too) as data corruption
  seems rather common on the device and it's unlikely to get any love in
  the foreseeable future.  If the whining doesn't draw any attention, I
  think we'd probably be better of making the driver depend on BROKEN in
  a couple releases"

8e5c2b776a Revert "ACPI / video / i915: No ACPI backlight if firmware expects Windows 8"
We attempted to address a regression introduced by commit a57f7f9
(ACPICA: Add Windows8/Server2012 string for _OSI method.) after which
ACPI video backlight support doesn't work on a number of systems,
because the relevant AML methods in the ACPI tables in their BIOSes
become useless after the BIOS has been told that the OS is compatible
with Windows 8.  That problem is tracked by the bug entry at:

https://bugzilla.kernel.org/show_bug.cgi?id=51231

Commit 8c5bd7a (ACPI / video / i915: No ACPI backlight if firmware
expects Windows 8) introduced for this purpose essentially prevented
the ACPI backlight support from being used if the BIOS had been told
that the OS was compatible with Windows 8 and the i915 driver was
loaded, in which case the backlight would always be handled by i915.
Unfortunately, however, that turned out to cause problems with
backlight to appear on multiple systems with symptoms indicating that
i915 was unable to control the backlight on those systems as
expected.

For this reason, revert commit 8c5bd7a, but leave the function
acpi_video_backlight_quirks() introduced by it, because another
commit on top of it uses that function.
