Pull media updates from Mauro Carvalho Chehab:
- Media documentation is now split into admin-guide, driver-api and
userspace-api books (a longstanding request from Jon);
- The media Kconfig was reorganized, in order to make easier to select
drivers and their dependencies;
- The testing drivers now has a separate directory;
- added a new driver for Rockchip Video Decoder IP;
- The atomisp staging driver was resurrected. It is meant to work with
4 generations of cameras on Atom-based laptops, tablets and cell
phones. So, it seems worth investing time to cleanup this driver and
making it in good shape.
- Added some V4L2 core ancillary routines to help with h264 codecs;
- Added an ov2740 image sensor driver;
- The si2157 gained support for Analog TV, which, in turn, added
support for some cx231xx and cx23885 boards to also support analog
standards;
- Added some V4L2 controls (V4L2_CID_CAMERA_ORIENTATION and
V4L2_CID_CAMERA_SENSOR_ROTATION) to help identifying where the camera
is located at the device;
- VIDIOC_ENUM_FMT was extended to support MC-centric devices;
- Lots of drivers improvements and cleanups.

There have been cases where seemingly innocuous patches have broken the
uAPI by changing the memory layout of the parameter struct. Generally such
changes also introduce a change in the size of the entire struct. This
patch adds a sanity check to avoid such cases happening in the future.

This reverts commit c9d52c114a9fcc61c30512c7f810247a9f2812af.
The patch being reverted changed the memory layout of struct
ipu3_uapi_acc_param. Revert it, and address the compiler warning issues in
further patches.

When queuing parameters fails, current code bails out without deleting
the corresponding vb2 buffer from the driver buffer list, but the buffer
is returned to vb2. This leads to stale list entries and a crash when
the driver stops streaming:

ImgU need set the mmu page table in memory as uncached, and set back
to write-back when free the page table by set_memory_wb(),
set_memory_wb() can not do flushing without interrupt, so the spinlock
should not be hold during ImgU page alloc and free, the interrupt
should be enabled during memory cache flush.
This patch release spinlock before freeing pages table.

There are lots of drivers that only work when the media controller
and/or the V4L2 subdev APIs are present.
Right now, someone need to first enable those APIs before
using those drivers.
Well, ideally, drivers, should, instead *optionally*
depend on it, in order for PC camera drivers to be able to use
them, but nowadays most drivers are UVC cameras, with don't
require a sensor driver.
So, be it.
Let's instead make them select the MEDIA_CONTROLLER and the
SUBDEV API, in order to make easier for people to be able
of enabling them.

Currently, imgu is working on 450MHz for all cases, however
in some cases (input frame less than 2048x1152), the imgu
did not need work in high frequency.
This patch make imgu work on 200MHz if the imgu input
frame is less than 2048x1152 to save power.

Imgu should still keep the capability and flexibility to allow user to

frames with less system load and power than still pipe.

Currently, the imgu running mode need user to set by v4l2 ctrl.
However, imgu only support 2 pipes and 2 operation modes - video and
still. This patch make the first imgu subdev running as video and second
one running as still, it will make the user understand easily, it can
also cover current camera use cases requirement. The running mode is set
during subdev registering, no race-condition after change, so it is safe
to change the mode data type to integer.

There are lots of places where we're doing 1 << 31. That's bad,
as, depending on the architecture, this has an undefined behavior.
The BIT() macro is already prepared to handle this, so, let's
just switch all "1 << number" macros by BIT(number) at the header files
with has 1 << 31.

Current ImgU driver processes and releases the parameter buffer
immediately after queued from user. This does not align with other
image buffers which are grouped in sets and used for the same frame.
If user queues multiple parameter buffers continuously, only the last
one will take effect.
To make consistent buffers usage, this patch changes the parameter
buffer handling and group parameter buffer with other image buffers
for each frame.
Each time driver will queue one more group of buffers when previous
frame processed and buffers consumed by css.
