04ee585495 spi/imx: use soc name in spi device type naming scheme
Software defined version number is not stable enough to be used
in device type naming scheme.  The patch changes it to use implicit
soc name for spi device type definition.  In this way, we can easily
align the naming scheme with device tree binding, which comes later.

It removes fifosize from spi_imx_data and adds devtype there, so that
fifosize can be set in an inline function according to devtype.
Also, cpu_is_mx can be replaced by inline functions checking devtype.

Since the A4LC should only be powered off if the A3RV is off, make
the A4LC's power down routine return -EBUSY if A3RV is not off to
indicate to the core that it doesn't want to power off the domain in
that case.  This will cause the core to regard A4LC as active, so
the pm_genpd_poweron() in pd_power_down_a3rv() is not necessary any
more.

c8c9fda506 OMAP: PM: disable idle on suspend for GPIO and UART
Until these drivers are runtime PM converted, their device power
states are managed by calling custom driver hooks late in the
idle/suspend path.  Therefore, do not let the suspend/resume core code
automatically idle these devices since they will be managed manually
by the OMAP PM core very late in the idle/suspend path.

c03f007a8b OMAP: PM: omap_device: add system PM methods for PM domain handling
In the omap_device PM domain callbacks, use omap_device idle/enable to
automatically manage device idle states during system suspend/resume.

If an omap_device has not already been runtime suspended, the
->suspend_noirq() method of the PM domain will use omap_device_idle()
to idle the HW after calling the driver's ->runtime_suspend()
callback.  Similarily, upon resume, if the device was suspended during
->suspend_noirq(), the ->resume_noirq() method of the PM domain will
use omap_device_enable() to enable the HW and then call the driver's
->runtime_resume() callback.

If a device has already been runtime suspended, the noirq methods of
the PM domain leave the device runtime suspended by default.

However, if a driver needs to runtime resume a device during suspend
(for example, to change its wakeup settings), it may do so using
pm_runtime_get* in it's ->suspend() callback.

f299bb9527 arm: davinci: Fix low level gpio irq handlers' argument
Commit 7416401 ("arm: davinci: Fix fallout from generic irq chip
conversion") introduced a bug, causing low level interrupt handlers to
get a bogus irq number as an argument. The gpio irq handler falsely
assumes that the handler data is the irq base number and that is no
longer true.

Set the irq handler data to be a pointer to the corresponding gpio
controller. The chained irq handler can then use it to extract both the
irq base number and the gpio registers structure.

9c0de4947a ARM: pxa/raumfeld: fix device name for codec ak4104
In commit f0fba2ad (ASoC: multi-component - ASoC Multi-Component
Support), the name of the ak4104 codec driver was changed without
amending the platform code which uses it as well.

a74fe1194b ARM: pxa/raumfeld: display initialisation fixes
The display requires some milliseconds between GPIO_TFT_VA_EN
and GPIO_DISPLAY_ENABLE. Reorder initialisation to comply with
the display spec.

Also tune timings for better compliance with the spec.

a065685d2f ARM: pxa: fix gpio_to_chip() clash with gpiolib namespace
The PXA platform code has a static inline helper called
gpio_to_chip which clashes with the gpiolib namespace if we
try to expose the function with the same name from gpiolib,
and it's still confusing even if we don't do that. So rename
it to gpio_to_pxachip().

775b8ae870 ARM: mach-shmobile: sh7372 A3RV requires A4LC
Add a power domain workaround for the VPU and A3RV on sh7372.

The sh7372 data sheet mentions that the VPU is located in the
A3RV power domain. The A3RV power domain is not related to A4LC
in any way, but testing shows that unless A3RV _and_ A4LC are
powered on the VPU test program will bomb out.

This issue may be caused by a more or less undocumented dependency
on the MERAM block that happens to be located in A4LC. So now we
know that the out-of-reset requirement of the VPU is that the MERAM
is powered on.

This patch adds a workaround for A3RV to make sure A4LC is powered
on - this so we can use the VPU even though the LCDCs are in blanking
state and A4LC is supposed to be off.

14305e685d ARM: mxc: use ARCH_NR_GPIOS to define gpio number
The patch removes MXC_GPIO_IRQS and instead uses ARCH_NR_GPIOS to
define gpio number.  This change is need when we change mxc gpio
driver to be device tree aware.  When migrating the driver to device
tree, pdev->id becomes unusable.  It requires driver get gpio range
from gpio core, which will dynamically allocates number from
ARCH_NR_GPIOS to 0.

As a bonus point, it removes lines of '#if' and make the code a
little bit cleaner.  The side effect is the waste of number.  But
this is not a point when we go single image.
