cd8adbe701 [media] vivid: add new colorspaces
Add AdobeRGB and BT.2020 support.

The colorspace control now orders the colorspaces according to how often
they are used. So rarely used colorspaces are moved to the end. This makes
it more logical when testing colorspace support.

This extends the precalculated tpg_csc_colors matrix with AdobeRGB and BT.2020
colorspace support.

It also adds two precalculated tables that convert between linear RGB and non-linear
Rec.709 R'G'B' values, i.e. the Rec. 709 transfer function. This is needed to
efficiently handle the BT.2020 Constant Luminance Yc'CbcCrc encoding and decoding.

12ddbadf38 [media] media: rc: add driver for Amlogic Meson IR remote receiver
Amlogic Meson SoCs include a infrared remote control receiver that can
operate in two modes: "NEC" mode in which the hardware decodes frames
using the NEC IR protocol, and "general" mode in which the receiver
simply reports the duration of pulses and spaces for software
decoding.

This is a driver for the IR receiver that implements software decoding
of received frames.

504febc3f9 Revert "[media] lmed04: add missing breaks"
According with Malcolm, the missing breaks are intentional.

So, let's revert commit d442b15fb4deb2b5d516e2dae1f569b1d5472399,
add some comments to document it and fix the two smatch warnings:

drivers/media/usb/dvb-usb-v2/lmedm04.c:828 lme_firmware_switch() warn: missing break? reassigning 'st->dvb_usb_lme2510_firmware'
drivers/media/usb/dvb-usb-v2/lmedm04.c:850 lme_firmware_switch() warn: missing break? reassigning 'st->dvb_usb_lme2510_firmware'

using a different strategy to avoid reassign values to
st->dvb_usb_lme2510_firmware.

By default dma_map_sg syncs the mapped buffer to the device. But
buf_prepare expects a buffer syncs for the cpu and the buffer
will be synced to the device in the prepare memop.

The reverse is true for dma_unmap_sg, buf_finish and the finish
memop.

To prevent unnecessary syncs we ask dma_(un)map_sg to skip the
sync.

d790b7eda9 [media] vb2-dma-sg: move dma_(un)map_sg here
This moves dma_(un)map_sg to the get_userptr/put_userptr and alloc/put
memops of videobuf2-dma-sg.c and adds dma_sync_sg_for_device/cpu to the
prepare/finish memops.

Now that vb2-dma-sg will sync the buffers for you in the prepare/finish
memops we can drop that from the drivers that use dma-sg.

For the solo6x10 driver that was a bit more involved because it needs to
copy JPEG or MPEG headers to the buffer before returning it to userspace,
and that cannot be done in the old place since the buffer there is still
setup for DMA access, not for CPU access. However, the buf_finish
op is the ideal place to do this. By the time buf_finish is called
the buffer is available for CPU access, so copying to the buffer is fine.

This is needed for the next patch where the dma-sg alloc memop needs
to know the dma_dir.

cd474037c4 [media] vb2: replace 'write' by 'dma_dir'
The 'write' argument is very ambiguous. I first assumed that if it is 1,
then we're doing video output but instead it meant the reverse.

Since it is used to setup the dma_dir value anyway it is now replaced by
the correct dma_dir value which is unambiguous.

ef33d901db [media] uvcvideo: Return all buffers to vb2 at stream stop and start failure
videobuf2 requires drivers to give back ownership of all queue buffers
in the stop_streaming operation, as well as in the start_streaming
operation in case of failure. Mark all queued buffers as done in the
error or queued state.

0da4ab984b [media] uvcvideo: Rename and split uvc_queue_enable to uvc_queue_stream(on|off)
This brings the function name in line with the V4L2 API terminology and
allows removing the duplicate queue type check.

3f02de275e [media] uvcvideo: Don't stop the stream twice at file handle release
When releasing the file handle the driver calls the vb2_queue_release
which turns the stream off. There's thus no need to turn the stream off
explicitly beforehand.

a11a03e50b [media] uvcvideo: Implement vb2 queue start and stop stream operations
To work propertly the videobuf2 core code needs to be in charge of
stream start/stop control. Implement the start_streaming and
stop_streaming vb2 operations and move video enable/disable code to
them.
