Commit c111feab (gpio: twl4030: Cache the direction and output
states in private data) improved things in general, but caused a
regression for setting the GPIO output direction.

The change reorganized twl_direction_out() and twl_set() and swapped
the function names around in the process. While doing that, a bug got
introduced that's not obvious while reading the patch as it appears
as no change to the code.

The bug is we now call function twl4030_set_gpio_dataout() twice in
both twl_direction_out() and twl_set(). Instead, we should first
call twl_direction_out() in twl_direction_out() followed by
twl4030_set_gpio_dataout() in twl_set().

This regression probably has gone unnoticed for a long time as the
bootloader may have set the GPIO direction properly in many cases.
This fixes at least the LCD panel not turning on omap3 LDP for
example.

Commit 26273e02 (ARM: OMAP2+: Fix build for dra7xx without
omap4 and 5) attempted to fix randconfig found errors for
redefinition of omap44xx_prm_reconfigure_io_chain, but was
not enough.

We need to check for AM43XX without any omap4 or 5 related
SoCs as well. And looks like we have prm44xx.o built always
anyways with omap-4-5-prcm-common because of the calls to
omap4_prm_vp_clear_txdone, so we can remove the duplicate
entries in the Makefile.

Looks like we're missing few entries for omap2 and the drivers
have only worked because of the omap hwmod building the devices
for the missing entries.

Let's fix the missing entries so we don't need to rely on hwmod
for the basic data and can then later on remove the duplicate
data from hwmod. Otherwise device tree only drivers will not
work properly.

Commit f2bf0e72 (ARM: OMAP2+: Add minimal 8250 support

flags of the child without adding a new function as smc91x has
a similar issue as 8250 with the bootloader timings.

OMAP device hooks around suspend|resume_noirq ensures that hwmod
devices are forced to idle using omap_device_idle/enable as part of
the last stage of suspend activity.

For a device such as i2c who uses autosuspend, it is possible to enter
the suspend path with dev->power.runtime_status = RPM_ACTIVE.

As part of the suspend flow, the generic runtime logic would increment
it's dev->power.disable_depth to 1. This should prevent further
pm_runtime_get_sync from succeeding once the runtime_status has been
set to RPM_SUSPENDED.

Now, as part of the suspend_noirq handler in omap_device, we force the
following: if the device status is !suspended, we force the device
to idle using omap_device_idle (clocks are cut etc..). This ensures
that from a hardware perspective, the device is "suspended". However,
runtime_status is left to be active.

*if* an operation is attempted after this point to
pm_runtime_get_sync, runtime framework depends on runtime_status to
indicate accurately the device status, and since it sees it to be
ACTIVE, it assumes the module is functional and returns a non-error
value. As a result the user will see pm_runtime_get succeed, however a
register access will crash due to the lack of clocks.

To prevent this from happening, we should ensure that runtime_status
exactly indicates the device status. As a result of this change
any further calls to pm_runtime_get* would return -EACCES (since
disable_depth is 1). On resume, we restore the clocks and runtime
status exactly as we suspended with. These operations are not expected
to fail as we update the states after the core runtime framework has
suspended itself and restore before the core runtime framework has
resumed.

Pull GPIO changes from Linus Walleij:
 "Here is the bulk of GPIO changes for the v3.13 development cycle.

  I've got ACKs for the things that affect other subsystems (or it's my
  own subsystem, like pinctrl).  Most of that pertain to an attempt from
  my side to consolidate and get rid of custom GPIO implementations in
  the ARM tree.  I will continue doing this.

  The main change this time is the new GPIO descriptor API, background
  for this can be found in Corbet's summary from this january in LWN:

    http://lwn.net/Articles/533632/

  Summary:

   - Merged the GPIO descriptor API from Alexandre Courbot.  This is a
     first step toward trying to get rid of the global GPIO numberspace
     for the future.

   - Add an API so that driver can flag that a certain GPIO line is
     being used by a irqchip backend for generating IRQs, so that we can
     enforce checks, like not allowing users to switch that line to an
     output at runtime, since this makes no sense.  Implemented
     corresponding calls in a few select drivers.

   - ACPI GPIO cleanups, refactorings and switch to using the
     descriptor-based interface.

   - Support for the TPS80036 Palmas GPIO variant.

   - A new driver for the Broadcom Kona GPIO SoC IP block.

   - Device tree support for the PCF857x driver.

   - A set of ARM GPIO refactorings with the goal of getting rid of a
     bunch of custom GPIO implementations from the arch/arm/* tree:

     * Move the IOP GPIO driver to the GPIO subsystem and fix all users
       to use the gpiolib API for accessing GPIOs.  Delete the old
       custom GPIO implementation.

     * Delete the unused custom PXA GPIO implemention.

     * Convert all users of the IXP4 custom GPIO implementation to use
       gpiolib and delete the custom implementation.

     * Delete the custom Gemini GPIO implementation, also completely
       unused.

   - Various cleanups and renamings"

 "Main pin control pull request for the v3.13 cycle.

  The changes hitting arch/blackfin are ACKed by the Blackfin
  maintainer, and the device tree bindings are ACKed to the extent
  possible by someone from the device tree maintainers group.

   - Blackfin ADI pin control driver, we move yet another architecture
     under this subsystem umbrella.

   - Incremental updates to the Renesas Super-H PFC pin control driver.
     New subdriver for the r8a7791 SoC.

   - Non-linear GPIO ranges from the gpiolib side of things, this
     enabled simplified device tree bindings by referring entire groups
     of pins on some pin controller to act as back-end for a certain
     GPIO-chip driver.

   - Add the Abilis TB10x pin control driver used on the ARC
     architecture.  Also the corresponding GPIO driver is merged through
     this tree, so the ARC has full support for pins and GPIOs after
     this.

   - Subdrivers for Freescale i.MX1, i.MX27 and i.MX50 pin controller
     instances.  The i.MX1 and i.MX27 is an entirely new family
     (silicon) of controllers whereas i.MX50 is a variant of the
     previous supported controller.

   - Then the usual slew of fixes, cleanups and incremental updates"

sorted out in a timely manner.

Pull powerpc updates from Benjamin Herrenschmidt:
 "The bulk of this is LE updates.  One should now be able to build an LE
  kernel and even run some things in it.

  I'm still sitting on a handful of patches to enable the new ABI that I
  *might* still send this merge window around, but due to the
  incertainty (they are pretty fresh) I want to keep them separate.

  Other notable changes are some infrastructure bits to better handle
  PCI pass-through under KVM, some bits and pieces added to the new
  PowerNV platform support such as access to the CPU SCOM bus via sysfs,
  and support for EEH error handling on PHB3 (Power8 PCIe).

  We also grew arch_get_random_long() for both pseries and powernv when
  running on P7+ and P8, exploiting the HW rng.

  And finally various embedded updates from freescale"
