fc04023faf drm/vc4: Add support for YUV planes. 
This supports 420 and 422 subsampling with 2 or 3 planes, tested with
modetest.  It doesn't set up chroma subsampling position (which it
appears KMS doesn't deal with yet).

The LBM memory is overallocated in many cases, but apparently the docs
aren't quite correct and I'll probably need to look at the hardware
source to really figure it out.

d8dbf44f13 drm/vc4: Make the CRTCs cooperate on allocating display lists. 
So far, we've only ever lit up one CRTC, so this has been fine.  To
extend to more displays or more planes, we need to make sure we don't
run our display lists into each other.

6674a904d6 drm/vc4: Add a proper short-circut path for legacy cursor updates. 
Previously, on every modeset we would allocate new display list
memory, recompute changed planes, write all of them to the new memory,
and pointed scanout at the new list (which will latch approximately at
the next line of scanout).  We let
drm_atomic_helper_wait_for_vblanks() decide whether we needed to wait
for a vblank after a modeset before cleaning up the old state and
letting the next modeset proceed, and on legacy cursor updates we
wouldn't wait.  If you moved the cursor fast enough, we could
potentially wrap around the display list memory area and overwrite the
existing display list while it was still being scanned out, resulting
in the HVS scanning out garbage or just halting.

Instead of making cursor updates wait for scanout to move to the new
display list area (which introduces significant cursor lag in X), we
just rewrite our current display list.

Such error happens at the memcpy code below:

0x4bc0 is in smscore_set_device_mode (drivers/media/common/siano/smscoreapi.c:975).
970					      sizeof(u32) + payload_size));
971
972			data_msg->mem_addr = mem_address;
973			memcpy(data_msg->payload, payload, payload_size);
974
975			rc = smscore_sendrequest_and_wait(coredev, data_msg,
976					data_msg->x_msg_header.msg_length,
977					&coredev->data_download_done);
978
979			payload += payload_size;

The problem is that the Siano driver uses a header to store the firmware,
with requires a few more bytes than allocated.

Tested with:
	PCTV 77e (2013:0257)
	Hauppauge WinTV MiniStick (2040:5510)

1f4522400e [media] [for,v4.5] media.h: increase the spacing between function ranges 
Each function range is quite narrow and especially for connectors this
will pose a problem. Increase the function ranges while we still can and
move the connector range to the end so that range is practically limitless.

c43875f661 [media] tvp5150: replace MEDIA_ENT_F_CONN_TEST by a control 
MEDIA_ENT_F_CONN_TEST is not really a connector, it is actually
a signal generator. Also, as other drivers use the
V4L2_CID_TEST_PATTERN control for signal generators, let's change
the driver accordingly.

Tested with Terratec Grabster AV350.

153d41a1d0 [media] v4l2-mc: remove the unused sensor var 
This fixes this warning:

	v4l2-mc.c: In function 'v4l2_mc_create_media_graph':
	v4l2-mc.c:60:69: warning: variable 'sensor' set but not used [-Wunused-but-set-variable]

We could solve it the other way: don't do the second loop for
webcams. However, that would fail if a chip would have two sensors
plugged. This is not the current case, but it doesn't hurt to be
future-safe here, specially since this code runs only once during
device probe. So, performance is not an issue here.

133bc4e4a3 [media] cx231xx, em28xx: pass media_device to si2157 
As si2157 doesn't use the subdev, but has instead a binding
logic that doesn't have any core framework, we need to manually
pass the media_device struct via platform data on every place
it is called.

This fixes support for HVR-955Q when MC is enabled.
