Pull MIPS updates from Ralf Baechle:
- More work on DT support for various platforms
- Various fixes that were to late to make it straight into 3.9
- Improved platform support, in particular the Netlogic XLR and
BCM63xx, and the SEAD3 and Malta eval boards.
- Support for several Ralink SOC families.
- Complete support for the microMIPS ASE which basically reencodes the
existing MIPS32/MIPS64 ISA to use non-constant size instructions.
- Some fallout from LTO work which remove old cruft and will generally
make the MIPS kernel easier to maintain and resistant to compiler
optimization, even in absence of LTO.
- KVM support. While MIPS has announced hardware virtualization
extensions this KVM extension uses trap and emulate mode for
virtualization of MIPS32. More KVM work to add support for VZ
hardware virtualizaiton extensions and MIPS64 will probably already
be merged for 3.11.
Most of this has been sitting in -next for a long time. All defconfigs
have been build or run time tested except three for which fixes are being
sent by other maintainers.

commit 6cd2c7db4 (videomode: videomode_from_timing work) changed the name of
the function from videomode_from_timing() to videomode_from_timings().
commit 32ed6ef1 (videomode: create enum for videomode's display flags) changed
the 'data_flags' field in videomode structure to 'flags'
Adapt to these changes in order to fix the following errors:
drivers/video/mxsfb.c:761:3: error: too many arguments to function 'videomode_from_timing'
drivers/video/mxsfb.c:761:7: error: void value not ignored as it ought to be

drivers/video/mxsfb.c:770:9: error: 'struct videomode' has no member named 'data_flags'
Also, select VIDEOMODE_HELPER instead of OF_VIDEOMODE, as this one is
deprecated.

The support for PB1100, PB1500, and PB1550 got merged into the code for
DB1000 and DB1550 code in v3.7. When that was done the three related
Kconfig symbols were dropped. But not all related Kconfig macros were
removed. Do so now.
Note that the PB1100 code in the Au1100 LCD driver is removed entirely
and not converted to use its current Kconfig macro. That is done because
the macros it uses (PB1100_G_CONTROL, PB1100_G_CONTROL_BL, and
PB1100_G_CONTROL_VDD) are never defined. Actually only one of these was
ever defined (PB1100_G_CONTROL) but that define was removed in v2.6.34.
So, as far as I can tell, this code could have never compiled.

Pull ARM SoC driver changes from Olof Johansson:
"This is a rather large set of patches for device drivers that for one
reason or another the subsystem maintainer preferred to get merged
through the arm-soc tree. There are both new drivers as well as
existing drivers that are getting converted from platform-specific
code into standalone drivers using the appropriate subsystem specific
interfaces.
In particular, we can now have pinctrl, clk, clksource and irqchip
drivers in one file per driver, without the need to call into platform
specific interface, or to get called from platform specific code, as
long as all information about the hardware is provided through a
device tree.
Most of the drivers we touch this time are for clocksource. Since now
most of them are part of drivers/clocksource, I expect that we won't
have to touch these again from arm-soc and can let the clocksource
maintainers take care of these in the future.
Another larger part of this series is specific to the exynos platform,
which is seeing some significant effort in upstreaming and
modernization of its device drivers this time around, which
unfortunately is also the cause for the churn and a lot of the merge
conflicts.
There is one new subsystem that gets merged as part of this series:
the reset controller interface, which is a very simple interface for
taking devices on the SoC out of reset or back into reset. Patches to
use this interface on i.MX follow later in this merge window, and we
are going to have other platforms (at least tegra and sirf) get
converted in 3.11. This will let us get rid of platform specific
callbacks in a number of platform independent device drivers."

omapfb requires the panel drivers to have been probed when omapfb is
initialized. omapfb does not support insertion of new panels after its
probe. This causes a problem in case omapdss or the panel probes have
been deferred due to EPROBE_DEFER error, as omapfb won't find any
displays.
As a quick fix, this patch changes the omapfb probe so that if omapfb
does not find any displays, it'll return EPROBE_DEFER. This is not
perfect, as with a board with no displays, omapfb will get deferred
forever. Also, if the board has multiple displays, but only some of them
have been probed, omapfb will start and leave the unprobed displays out.

omapfb requires the panels to have been probed before omapfb's probe. We

be updated or not.
However, we can decide it with 'size_program' data. If the size is

The brightness of LP855x devices is controlled by I2C register or PWM
input . This mode was selected through the platform data, but it can be
chosen by the driver internally without platform data configuration.
How to decide the control mode:
If the PWM period has specific value, the mode is PWM input.
On the other hand, the mode is register-based.
This mode selection is done on the _probe().
Move 'mode' from a header file to the driver private data structure,
'lp855 x'. And correlated code was replaced.

Instead of using legacy suspend/resume methods, using newer dev_pm_ops
structure allows better control over power management. Also, use of
pm_message_t is deprecated. Thus, it is removed.

Platform LCD devices may need to do some device-specific initialization
before they can be used (regulator or GPIO setup, for example), but
currently the driver does not support any way of doing this. This patch
adds a probe() callback to plat_lcd_data which platform LCD devices can
set to indicate that device-specific initialization is needed.

Use the wrapper functions for getting and setting the driver data using
spi_device instead of using dev_{get|set}_drvdata with &spi->dev, so we
can directly pass a struct spi_device.

Fix three typos (originally) introduced by commit a9a84c37d1ee
("atmel_lcdfb: backlight control").
Two of these typos were introduced in v2.6.25. (The third was
introduced in 915190f7d4f0 ("[ARM] 5614/1: at91: atmel_lcdfb: add
at91sam9g10 support to atmel LCD driver")). Checking these commits
reveals that the default value of 'y' has never been set automatically
in all releases since v2.6.25! Perhaps this line might as well be
dropped.
