Most likely the last pull request from me for omap changes for
v3.16 that's dts fixes for clocks and enabling few features
that were still being discussed earlier:
- A bunch of omap clock related dts fixes queued by Tero Kristo.
- Enable parallel nand on am437x that was not merged earlier as
I requested more information about the muxing for it. And
we need to also enable ecc hardware support for am43xx.
- Enable the modem support for n900 that was dropped earlier
because we had to fix the related hwmod entry first with patch
ARM: OMAP2+: Fix ssi hwmod entry to allow idling.
- And finally, add the omap2 clock dts files. These will allow
us to enable the dt clocks and drop the legacy clocks for omap2
with a follow-up patch once the related clock driver binding
changes are merged.

mfd: twl4030-power: Add generic reset configuration
The twl4030 PMIC needs to be configured properly for things like
warm reset and deeper idle states so the PMIC manages the regulators
properly based on the hardware triggers from the SoC. Earlier
we have configured twl4030 using platform data, but we want to
do it for device tree based booting also.
In some cases configuring twl4030 is needed for things to work.
For example, when rebooting an OMAP3530 at 125 MHz, it hangs.
With this patch, TWL4030 will be reset when a warm reset occures,
and OMAP3530 does not hang on reboot.
Let's add device tree support and configure things for warm reset
as the default when compatible = "ti,twl4030-power". More
complicated configurations can be added to the driver based on
other compatible flags.
Note we now also make the pdata const like it should be.
This allows use it for match->data with the device tree

in a way where we can test for PM regressions easily by
looking at state of the the sys_clkreq and sys_off_mode pins.
Note that this series alone does not make omap3 PM to cut
off core voltage during off-idle, changes to twl4030-power.c

ARM: OMAP4: Fix the boot regression with CPU_IDLE enabled
On OMAP4 panda board, there have been several bug reports about boot
hang and lock-ups with CPU_IDLE enabled. The root cause of the issue
is missing interrupts while in idle state. Commit
cb7094e8 {cpuidle / omap4 :
use CPUIDLE_FLAG_TIMER_STOP flag} moved the broadcast notifiers to common
code for right reasons but on OMAP4 which suffers from a nasty ROM code
bug with GIC, commit
ff999b8a {ARM: OMAP4460: Workaround for ROM bug ..},
we loose interrupts which leads to issues like lock-up, hangs etc.
Patch reverts commit cb7094 {cpuidle / omap4 : use CPUIDLE_FLAG_TIMER_STOP
flag} and 54769d6 {cpuidle: OMAP4: remove timer broadcast initialization} to
avoid the issue. With this change, OMAP4 panda boards, the mentioned
issues are getting fixed. We no longer loose interrupts which was the cause
of the regression.

ARM: OMAP2+: Fix DMA hang after off-idle
Commit
6ddeb6d84459 (dmaengine: omap-dma: move IRQ handling to omap-dma)
added support for handling interrupts in the omap dmaengine driver
instead of the legacy driver. Because of different handling for
interrupts this however caused omap3 to hang eventually after hitting
off-idle.
Any of the virtual 32 DMA channels can be assigned to any of the
four DMA interrupts. So commit
6ddeb6d84459 made the omap dmaengine
driver to use the second DMA interrupt while keeping the legacy code
still using the first DMA interrupt.
This means we need to save and restore both IRQENABLE_L1 in addition
to IRQENABLE_L0. As there is a chance that the DSP might be using
IRQENABLE_L2 or IRQENABLE_L3 lines, let's not touch those until
this has been confirmed. Let's just add a comment to the code for
now.

x86, vdso, time: Cast tv_nsec to u64 for proper shifting in update_vsyscall()
With tk->wall_to_monotonic.tv_nsec being a 32-bit value on 32-bit
systems, (tk->wall_to_monotonic.tv_nsec << tk->shift) in update_vsyscall()
may lose upper bits or, worse, add them since compiler will do this:
(u64)(tk->wall_to_monotonic.tv_nsec << tk->shift)
instead of
((u64)tk->wall_to_monotonic.tv_nsec << tk->shift)
So if, for example, tv_nsec is 0x800000 and shift is 8 we will end up
with 0xffffffff80000000 instead of 0x80000000. And then we are stuck in
the subsequent 'while' loop.
We need an explicit cast.

x86: Fix typo preventing msr_set/clear_bit from having an effect
Due to a typo the msr accessor function introduced in
22085a66c2fab6cf9b9393c056a3600a6b4735de didn't have any lasting
effects because they accidentally wrote the old value back.
After
c0a639ad0bc6b178b46996bd1f821a04643e2bde this at the very least
this causes cpuid limits not to be lifted on some cpus leading to
missing capabilities for those.

"The main fix is adding support for default ACLs on O_TMPFILE opened
inodes to bring XFS into line with other filesystems. Metadata CRCs
are now also considered well enough tested to be fully supported, so
we're removing the shouty warnings issued at mount time for
filesystems with that format. And there's transaction block
reservation overrun fix.

- fix a remote attribute size calculation bug that leads to a
transaction overrun
- add default ACLs to O_TMPFILE files
- Remove the EXPERIMENTAL tag from filesystems with metadata CRC
support"

The first is a long standing bug that causes bogus data to show up in

The result should be 'refcnt = incs - decs', but instead it did
'refcnt = incs + decs'.
The second fix is to a bug that was introduced in this merge window
that allowed for a tracepoint funcs pointer to be used after it was
freed. Moving the location of where the probes are released solved
the problem"

All OMAP IP blocks expect LE data, but CPU may operate in BE mode.
Need to use endian neutral functions to read/write h/w registers.
I.e instead of __raw_read[lw] and __raw_write[lw] functions code

If the first simply reads/writes register, the second will byteswap
