Fix the video clock setting when custom timings are used with
pclock <= 27MHz. Existing video clock selection uses PLL2 mode
which results in a 54MHz clock whereas using the MXI mode results
in a 27MHz clock (which is the one actually desired).
This bug affects the Enhanced Definition (ED) support on DM644x.
Without this patch, out-range signals errors are were observed on
the TV when viewing ED. An out-of-range signal is often caused when
the field rate is above the rate that the television will handle.

In case of error, the function clk_get() returns ERR_PTR() not

As suggested by Andrew Morton:
This is a pet peeve of mine. Any time there's a long list of items
(header file inclusions, kconfig entries, array initalisers, etc) and
someone wants to add a new item, they *always* go and stick it at the
end of the list.
Guys, don't do this. Either put the new item into a randomly-chosen
position or, probably better, alphanumerically sort the list.
lets sort all our select statements alphanumerically. This commit was
created by the following perl:
while (<>) {
while (/\\\s*$/) {
$_ .= <>;
}
undef %selects if /^\s*config\s+/;
if (/^\s+select\s+(\w+).*/) {
if (defined($selects{$1})) {
if ($selects{$1} eq $_) {
print STDERR "Warning: removing duplicated $1 entry\n";
} else {
print STDERR "Error: $1 differently selected\n".
"\tOld: $selects{$1}\n".
"\tNew: $_\n";
exit 1;
}
}
$selects{$1} = $_;
next;
}
if (%selects and (/^\s*$/ or /^\s+help/ or /^\s+---help---/ or
/^endif/ or /^endchoice/)) {
foreach $k (sort (keys %selects)) {
print "$selects{$k}";
}
undef %selects;
}
print;
}
if (%selects) {
foreach $k (sort (keys %selects)) {
print "$selects{$k}";
}
}
It found two duplicates:
Warning: removing duplicated S5P_SETUP_MIPIPHY entry
Warning: removing duplicated HARDIRQS_SW_RESEND entry
and they are identical duplicates, hence the shrinkage in the diffstat
of two lines.
We have four testers reporting success of this change (Tony, Stephen,
Linus and Sekhar.)

Pull second set of media updates from Mauro Carvalho Chehab:
"Despite its size, most of the stuff here is trivial. This series
contains:
- s5p-mfc: additions at the driver and at the core to support H.264
hardware codec;
- Some improvements at s5p and davinci embedded drivers;
- Some V4L2 compliance fixes applied on a few drivers;
- Several random trivial patches, including several fixes and a few
new board support additions;
Notes:
1) Some Exynos media patches were dependent on some -arm fixes that
got merged on changeset 782cd9e. That's why this pull request is
based that changeset.
2) As promised, I reviewed the pending VB2 DMABUF series.
While setting a test environment, it was noticed that the upstream
support for Samsung Exynos 4 boards (smdk310 and Origen) are
broken upstream, likely due to regressions: both defconfigs are
wrong and regulator settings for both boards are broken. That,
allied with some bug at the dummy regulator driver, causes OOPSes
during boot time.
Long story short: even fixing the above, the proposed patches
OOPSed when running the DMABUF test. Not sure yet if the OOPSes
are due to some other undetected regressions, or due to some bug
on the patches.
Due to the above, DMABUF patches for vb2 got NACKed for 3.7."

This contains pretty many small commits covering fairly large range of
files in sound/ directory. Partly because of additional API support
and partly because of constantly developed ASoC and ARM stuff.
Some highlights:
- Introduced the helper function and documentation for exposing the
channel map via control API, as discussed in Plumbers; most of PCI
drivers are covered, will follow more drivers later
- Most of drivers have been replaced with the new PM callbacks (if
the bus is supported)
- HD-audio controller got the support of runtime PM and the support of
D3 clock-stop. Also changing the power_save option in sysfs kicks
off immediately to enable / disable the power-save mode.
- Another significant code change in HD-audio is the rewrite of
firmware loading code. Other than that, most of changes in HD-audio
are continued cleanups and standardization for the generic auto
parser and bug fixes (HBR, device-specific fixups), in addition to
the support of channel-map API.
- Addition of ASoC bindings for the compressed API, used by the
mid-x86 drivers.
- Lots of cleanups and API refreshes for ASoC codec drivers and
DaVinci.
- Conversion of OMAP to dmaengine.
- New machine driver for Wolfson Microelectronics Bells.
- New CODEC driver for Wolfson Microelectronics WM0010.
- Enhancements to the ux500 and wm2000 drivers

The mityomapl138_cpufreq_init and read_factory_config function in
board-mityomapl138.c are not __init functions and might be called
at a later stage, so da850_register_cpufreq must not be __init either.
Without this patch, building da8xx_omapl_defconfig results in:
WARNING: arch/arm/mach-davinci/built-in.o(.text+0x2eb4): Section mismatch in reference from the function read_factory_config() to the function .init.text:da850_register_cpufreq()
The function read_factory_config() references
the function __init da850_register_cpufreq().
This is often because read_factory_config lacks a __init
annotation or the annotation of da850_register_cpufreq is wrong.

vpif_display relied on a 1-1 mapping of output and subdev. This is not
necessarily the case. Separate the two. So there is a list of subdevs
and a list of outputs. Each output refers to a subdev and has routing
information. An output does not have to have a subdev.
The initial output for each channel is set to the fist output.
Currently missing is support for associating multiple subdevs with
an output.

Davinci McASP header & driver are shared by few OMAP platforms (like
TI81xx, AM335x). Splitting asp header into Davinci platform specific
header and Audio specific header helps to share them across platforms.
Audio specific defines is moved to to common
<linux/platform_data/davinci_asp.h> so that the header can be
accessed by all related platforms.
While here, correct the header usage (remove multiple header
re-definitions and unused headers) and remove platform names from
structures comments and enum. Also some some coding style errors.

ntosd2_init_i2c walks the ntosd2_i2c_info array, which it expects to
be populated with at least one member. gcc correctly warns about
the out-of-bounds access here.
Since this can not possibly work, it's better to disable i2c
support entirely on this board.
Without this patch, building davinci_all_defconfig results in:
arch/arm/mach-davinci/board-neuros-osd2.c: In function 'davinci_ntosd2_init':

This branch contains two kinds of updates: Some platforms in the process
of getting converted to device tree based booting, and the platform
specific patches necessary for that are included here. Other platforms
are already converted, so we just need to update the actual device
tree source files and the binding documents to add support for new board
and new drivers.
In the future we will probably separate those into two branches, and
in the long run, the plan is to move the device tree source files out
of the kernel repository, but that has to wait until we have completed
a much larger portion of the binding documents.

CP_INTC code in entry-macro.S code reads SECR1n register to see if
an interrupt was indeed pending. This register is actually marked as
write-only in the OMAP-L138 TRM. Moreover, the code just checks to see
the entire register is non-zero and does not check a specific interrupt
number.
Fix this to use interrupt pending bit in GIPR register for this purpose.
GIPR register is already being read to know the highest priority interrupt
pending.

When runtime PM is enabled, the davinci runtime PM implementation will

This is a patch series from Shawn Guo that moves from individual
late_initcalls() to using a member in the machine structure to invoke
a platform's late initcalls.
This cleanup is a step in the move towards multiplatform kernels since
it would reduce the need to check for compatible platforms in each and
every initcall.

These changes are specific to some driver that may be used by multiple
boards or socs. The most significant change in here is the move of the
samsung iommu code from a platform specific in-kernel interface to the
generic iommu subsystem.

The ISR does quiete a lot of hw access which could be avoided. First it
checks for a pending interrupt by reading alteast one register. Then it
checks for the "activated" slots by reading another register. This is
more or a less a must.
Now, once it found an active slot it does the same two reads again.
After that it "knows" that there must be a pending transfer however it
cross checks with the other register. There are 32 bit in an interger
which are polled instead of considering only the set bits and ignoring
those which are zero. This performs atleast 32 reads which could be
avoided. In case of a first match it does another read.
This patch reorganizes the access by re-using the register which have
been read and then uses ffs() to find the matching slot instead looping
over it. By doing this we get rid of the last (32 + 2 + hits) reads.
It is possible however that by really busy bank0 we never get to handle
bank1. If this is a problem, we could try to handle bank1 after we are
done with bank0 to check if there are any outstanding transfers.
To put some numbers on this, this is from spi transfer via spidev. The
first column is the number of total transfers, the time stamp is taken
before and after the ioctl():
|10000, min: 542us avg: 591us
|20000, min: 542us avg: 592us
|30000, min: 542us avg: 592us
|40000, min: 542us avg: 585us
|50000, min: 542us avg: 593us
The same test case with the patch applied
|10000, min: 444us avg: 493us
|20000, min: 444us avg: 491us
|30000, min: 444us avg: 489us
|40000, min: 444us avg: 491us
|50000, min: 444us avg: 492us
that is almost 100us that just went away.

Apart from the necessity to do this change for multi-platform kernels
the previous logic depended on the zImage decompressor to write the
physical and virtual address to a magic memory location.
If the decompressor is unused or not correctly configured for the
current machid, the addruart macro was an infinite loop. Moreover
debugging the early zImage code was not possible either.

This fixes:
WARNING: arch/arm/mach-davinci/built-in.o(.text+0x2d84): Section mismatch in reference from the function da850_evm_ui_expander_setup() to the (unknown reference) .init.data:(unknown)
The function da850_evm_ui_expander_setup() references
the (unknown reference) __initdata (unknown).
This is often because da850_evm_ui_expander_setup lacks a __initdata
annotation or the annotation of (unknown) is wrong.
Note this is a real issue because if the tca6416 driver only binds when
the init sections are already discarded da850_evm_ui_expander_setup is
called when da850_evm_devices might already be overwritten.

Rob Herring has done a sweeping change cleaning up all of the mach/io.h includes,
moving some of the oft-repeated macros to a common location and removing a bunch of
boiler plate. This is another step closer to a common zImage for multiple platforms.
