Omap driver changes for v4.2 to switch drivers over to Linux generic

The generic wake IRQs also fix issues that these drivers potentially

ARM: SoC: defconfig updates for v4.2

We keep collecting defconfig updates in a separate branch mostly to encourage
people to handle them separately and avoid conflicts between different topics.

Most of these are enablement of new SoCs, boards or drivers that have
come in, or minor config refreshes due to reorderings in Kconfig
files, etc. I.e. mostly minor churn of various kinds.

Conflicts: None

ARM: SoC: driver updates for v4.2

Some of these are for drivers/soc, where we're now putting
SoC-specific drivers these days. Some are for other driver subsystems
where we have received acks from the appropriate maintainers.

Some highlights:

- simple-mfd: document DT bindings and misc updates
- migrate mach-berlin to simple-mfd for clock, pinctrl and reset
- memory: support for Tegra132 SoC
- memory: introduce tegra EMC driver for scaling memory frequency
- misc. updates for ARM CCI and CCN busses

 Conflicts:

 Trivial add/add conflict with our dt branch.

ARM: SoC: DT updates for v4.2

As usual, quite a few device-tree updates in ARM land.  There was ome
minor churn in DTs due to relicensing under a dual-license, and lots
of little additions of new peripherals, features etc, but nothing
really exciting to call to your attention.  Some higlights, focsuing
on support for new SoCs and boards:

- AT91: new boards: Overkiz,  Acme Systems' Arietta G25
- tegra: HDA support
- bcm: new platforms: Buffalo WXR-1900DHP, SmartRG SR400ac, ASUS RT-AC87U

v3.18 changed handle_IRQ() to call __handle_domain_irq(), which now
rejects attempts to deliver IRQ0.  Since IRQ 0 is used as the timer
interrupt (just like the PIT on x86), this causes boot to fail as the
bogomips calibration never completes.

Fix this by shuffling all interrupts up by one.

Since when we start discussions about the usage Media Controller for
complex hardware, one thing become clear: the way it is, MC fails to
map anything different than capture/output/m2m video-only streaming.

The point is that MC has entities named as devnodes, but the only
devnode used (before the DVB patches) is MEDIA_ENT_T_DEVNODE_V4L.
Due to the way MC got implemented, however, this entity actually
doesn't represent the devnode, but the hardware I/O engine that
receives data via DMA.

By coincidence, such DMA is associated with the V4L device node
on webcam hardware, but this is not true even for other V4L2
devices. For example, on USB hardware, the DMA is done via the
USB controller. The data passes though a in-kernel filter that
strips off the URB headers. Other V4L2 devices like radio may not
even have DMA. When it have, the DMA is done via ALSA, and not
via the V4L devnode.

In other words, MC is broken as a whole, but tagging it as BROKEN
right now would do more harm than good.

So, instead, let's mark, for now, the DVB part as broken and
block all new changes to MC while we fix this mess, whith
we hopefully will do for the next Kernel version.

It appears that, at some point last year, XFS made directory handling
changes which bring it into lockdep conflict with shmem_zero_setup():
it is surprising that mmap() can clone an inode while holding mmap_sem,
but that has been so for many years.

Since those few lockdep traces that I've seen all implicated selinux,
I'm hoping that we can use the __shmem_file_setup(,,,S_PRIVATE) which
v3.13's commit c7277090 ("security: shmem: implement kernel private
shmem inodes") introduced to avoid LSM checks on kernel-internal inodes:
the mmap("/dev/zero") cloned inode is indeed a kernel-internal detail.

This also covers the !CONFIG_SHMEM use of ramfs to support /dev/zero
(and MAP_SHARED|MAP_ANONYMOUS).  I thought there were also drivers
which cloned inode in mmap(), but if so, I cannot locate them now.
