Add new ioctls to set and get subdev client capabilities. Client in this
context means the userspace application which opens the subdev device
node. The client capabilities are stored in the file handle of the
opened subdev device node, and the client must set the capabilities for
each opened subdev.
For now we only add a single flag, V4L2_SUBDEV_CLIENT_CAP_STREAMS, which
indicates that the client is streams-aware.
The reason for needing such a flag is as follows:
Many structs passed via ioctls, e.g. struct v4l2_subdev_format, contain
reserved fields (usually a single array field). These reserved fields
can be used to extend the ioctl. The userspace is required to zero the
reserved fields.
We recently added a new 'stream' field to many of these structs, and the
space for the field was taken from these reserved arrays. The assumption
was that these new 'stream' fields are always initialized to zero if the
userspace does not use them. This was a mistake, as, as mentioned above,
the userspace is required to zero the _reserved_ fields. In other words,
there is no requirement to zero this new stream field, and if the
userspace doesn't use the field (which is the case for all userspace
applications at the moment), the field may contain random data.
This shows that the way the reserved fields are defined in v4l2 is, in
my opinion, somewhat broken, but there is nothing to do about that.
To fix this issue we need a way for the userspace to tell the kernel
that the userspace has indeed set the 'stream' field, and it's fine for
the kernel to access it. This is achieved with the new ioctl, which the
userspace should usually use right after opening the subdev device node.

A common case with subdev routing is that on the subdevice just before
the DMA engines (video nodes), no multiplexing is allowed on the source
pads, as the DMA engine can only handle a single stream.
In some other situations one might also want to do the same check on the
sink side.
Add new routing validation flags to check these:
V4L2_SUBDEV_ROUTING_NO_SINK_MULTIPLEXING and
V4L2_SUBDEV_ROUTING_NO_SOURCE_MULTIPLEXING.

V4L2_SUBDEV_ROUTING_NO_STREAM_MIX routing validation flag means that all
routes from a sink pad must go to the same source pad and all routes
going to the same source pad must originate from the same sink pad.
This does not cover all use cases. For example, if a device routes
all streams from a single sink pad to any of the source pads, but
streams from multiple sink pads can go to the same source pad, the
current flag is too restrictive.
Split the flag into two parts, V4L2_SUBDEV_ROUTING_NO_SINK_STREAM_MIX
and V4L2_SUBDEV_ROUTING_NO_SOURCE_STREAM_MIX, which add the restriction
only on one side of the device. Together they mean the same as
V4L2_SUBDEV_ROUTING_NO_STREAM_MIX.

Destructive overlay support (i.e. where the video frame is DMA-ed
straight into a framebuffer) is effectively dead. It was a
necessary evil in the early days when computers were not fast enough
to copy SDTV video frames around, but today that's no longer a problem.
It requires access to the framebuffer memory, which is a bad idea and
very hard to do safely. In addition, in drm it is today almost
impossible to get hold of the framebuffer address.
So drop support for this.

dvb_net.h includes a bunch of core networking headers which increases
the number of objects rebuilt when we touch them. They are unnecessary
for the header itself and only one driver has an indirect dependency.
tveeprom.h includes if_packet to gain access to ETH_ALEN. This
is a bit of an overkill because if_packet.h pulls in skbuff.h.
The definition of ETH_ALEN is in the uAPI header, which is
very rarely touched, so switch to including that.
This results in roughly 250 fewer objects built when skbuff.h
is touched (6028 -> 5788).

Add a common keymap for the RC10/RC0 and RC20/RC-BT remotes used with
the Dreambox One and Dreambox Two DVB-S/T boxes. The maps are combined
since the IR codes do not conflict and both boxes have shipped with
both remote designs over time.
Both remote types can be programmed to control TVs, so include non-IR
keys that are used to switch-to or toggle the remote mode:
- DREAM in RC10/RC0 switches to (Dreambox) STB control mode
- TV in RC10/RC0 switches to TV control mode
- MODE in RC20/RC-BT toggles between STB/TV/BT control modes
In the RC20 keymap the Android MIC (voice search) key maps to KEY_HELP
and EXIT is mapped to KEY_ESC to replicate the go-backwards navigation
behaviour in the Android vendor OS that ships on Dreambox devices.

This reverts commit e33fdb5a02.
The saa7146-based devices are still in use, esp. for DVB. So move
these drivers back to mainline.

The following drivers under drivers/media/i2c: ov08x40.c, ov13858.c,
ov13b10.c, ov2680.c, ov2685.c, ov2740.c, ov4689.c, ov5670.c,
ov5675.c, ov5695.c, ov8856.c, ov9282.c and ov9734.c,
as well as various "atomisp" sensor drivers in drivers/staging, *all*
use register access helpers with the following function prototypes:
int ovxxxx_read_reg(struct ovxxxx_dev *sensor, u16 reg,
unsigned int len, u32 *val);
int ovxxxx_write_reg(struct ovxxxx_dev *sensor, u16 reg,
unsigned int len, u32 val);
To read/write registers on Omnivision OVxxxx image sensors wich expect
a 16 bit register address in big-endian format and which have 1-3 byte
wide registers, in big-endian format (for the higher width registers).
Add a new ov_16bit_addr_reg_helpers.h header file with static inline
versions of these register access helpers, so that this code duplication
can be removed.

Add a media_pipeline_for_each_entity() macro to iterate over entities in
a pipeline. This should be used by driver as a replacement of the
media_graph_walk API, as iterating over the media_pipeline uses the
cached list of pads and is thus more efficient.
Deprecate the media_graph_walk API to indicate it shouldn't be used in
new drivers.

Make v4l2_async_register_subdev_sensor() try to get a privacy LED
associated with the sensor and extend the call_s_stream() wrapper to
enable/disable the privacy LED if found.
This makes the core handle privacy LED control, rather then having to
duplicate this code in all the sensor drivers.

The Cypress EZUSB FX3 UVC example can be configured to report pixel
format "e436eb7e-524f-11ce-9f53-0020af0ba770". This is its GUID for
BGRA/X 8:8:8:8.
The UVC 1.5 spec [1] only defines GUIDs for YUY2, NV12, M420 and I420.
This seems to be an extension documented in the Microsoft Windows Media
Format SDK[2]. This Media Format SDK defines this GUID as corresponding
to `MEDIASUBTYPE_RGB32`, which is confirmed by [4] as `MEDIASUBTYPE_ARGB32`
has different GUID.
Note that in my case, the FX3 UVC can output either channel order,
BGR or RGB or any other mix for that matter. Since Linux commit
1b8dc32286 ("[media] uvcvideo: Add GUID for BGR 8:8:8")
defined a GUID for `MEDIASUBTYPE_RGB24` channel order as BGR, keep
this change consistent and define `MEDIASUBTYPE_RGB32` as BGR as well.
Document [3] also indicates the channel order is BGR.

The vpfe_capture drivers do not use the vb2 framework for streaming
video, instead they use the old vb1 framework and nobody stepped in to
convert these drivers to vb2.
The hardware is very old, so the decision was made to remove them
altogether since we want to get rid of the old vb1 framework.

Add support for subdev internal routing. A route is defined as a single
stream from a sink pad to a source pad.
The userspace can configure the routing via two new ioctls,
VIDIOC_SUBDEV_G_ROUTING and VIDIOC_SUBDEV_S_ROUTING, and subdevs can
implement the functionality with v4l2_subdev_pad_ops.set_routing().
- Add sink and source streams for multiplexed links
- Copy the argument back in case of an error. This is needed to let the
caller know the number of routes.
- Expand and refine documentation.
- Make the 'routes' pointer a __u64 __user pointer so that a compat32
version of the ioctl is not required.
- Add struct v4l2_subdev_krouting to be used for subdevice operations.
- Fix typecasing warnings
