This driver makes it possible to configure the static memory
chip selects on the ARM PL172 MultiPort Memory Controller
from a set of properties in DT. Configuration of dynamic
memory is not supported and is left to the boot loader.
The intended usage is to setup timing and configuration for
static memory devices like NAND and NOR Flash before they
are probed by a driver.

In terms of peripherals the rk3368 is quite similar to the rk3288, which
makes it possible to have a lot basic components working in the first go.
More to follow once I tracked down all the tiny differences that still
exist in some parts.
With these dts files, the R88 board is able to boot from an attached
usb device and most likely from its emmc too, if the emmc uses a standard
partition table instead of Rockchip's own one - the emmc itself is
detected correctly.

An encrypted file name should never be shorter than an 16 bytes, the
AES block size. The 3.10 crypto layer will oops and crash the kernel
if ciphertext shorter than the block size is passed to it.
Fortunately, in modern kernels the crypto layer will not crash the
kernel in this scenario, but nevertheless, it represents a corrupted
directory, and we should detect it and mark the file system as
corrupted so that e2fsck can fix this.

Start a jbd2 transaction, and mark the inode dirty on the inode under
that transaction after setting the encrypt flag. Otherwise if the
directory isn't modified after setting the crypto policy, the
encrypted flag might not survive the inode getting pushed out from
memory, or the the file system getting unmounted and remounted.

Add videobuf2 specific vb2_qbuf and vb2_dqbuf trace events that mirror the
v4l2_qbuf and v4l2_dqbuf trace events, only they include additional
information about queue fill state and are emitted right before the buffer
is enqueued in the driver or userspace is woken up. This allows to make
sense of the timeline of trace events in combination with others that might
be triggered by __enqueue_in_driver.
Also two new trace events vb2_buf_queue and vb2_buf_done are added,
allowing to trace the handover between videobuf2 framework and driver.

Lots of devices support huge discard sizes these days. Depending
on how the device handles them internally, huge discards can
introduce massive latencies (hundreds of msec) on the device side.
We have a sysfs file, discard_max_bytes, that advertises the max
hardware supported discard size. Make this writeable, and split
the settings into a soft and hard limit. This can be set from
'discard_granularity' and up to the hardware limit.
Add a new sysfs file, 'discard_max_hw_bytes', that shows the hw
set limit.

Storing internal frames in macroblock tiled order improves memory
access patterns by allowing increased burst sizes when transferring
the uncompressed macroblocks to or from main memory.
The translation logic only supports a single chroma base address,
so this is only supported for the chroma interleaved NV12 format.
Since the rotator used to copy the decoder output into the v4l2
capture buffers does not seem to support the tiled format correctly,
only enable it in the encoder for now.

This patch changes the return type of snd_hdac_power_up/down() and
variants to pass the error code from the underlying
pm_runtime_get/put() calls. Currently they are ignored, but in most
places, these should be handled properly.
As an example, the regmap handler is updated to check the return value
and accesses the register only when the wakeup succeeds.

Linus noticed that the early return check was missing
_TIF_USER_RETURN_NOTIFY. If the only work flag was
_TIF_USER_RETURN_NOTIFY, we'd skip user return notifiers. Fix
it. (This is the only missing bit.)
This fixes double faults on a KVM host. It's the same issue as
last time, except that this time it's very easy to trigger.
Apparently no one uses -next as a KVM host.
( I'm still not quite sure what it is that KVM does that blows up
so badly if we miss a user return notifier. My best guess is that KVM
lets KERNEL_GS_BASE (i.e. the user's gs base) be negative and fixes
it up in a user return notifier. If we actually end up in user mode
with a negative gs base, we blow up pretty badly. )
