      [media] media: rc: Add rc_open/close and use count to rc_dev · 8b2ff320
      由 Srinivas Kandagatla 提交于 
      This patch adds user count to rc_dev structure, the reason to add this
new member is to allow other code like lirc to open rc device directly.
In the existing code, rc device is only opened by input subsystem which
works ok if we have any input drivers to match. But in case like lirc
where there will be no input driver, rc device will be never opened.
Having this user count variable will be usefull to allow rc device to be
opened from code other than rc-main.
This patch also adds rc_open and rc_close functions for other drivers
like lirc to open and close rc devices. This functions safely increment
and decrement the user count. Other driver wanting to open rc device
should call rc_open and rc_close, rather than directly modifying the
rc_dev structure.

      [media] mem2mem: add support for hardware buffered queue · 33bdd5a8
      由 Philipp Zabel 提交于 
      On mem2mem decoders with a hardware bitstream ringbuffer, to drain the
buffer at the end of the stream, remaining frames might need to be decoded
from the bitstream buffer without additional input buffers being provided.
To achieve this, allow a queue to be marked as buffered by the driver, and
allow scheduling of device_runs when buffered ready queues are empty.
This also allows a driver to copy input buffers into their bitstream
ringbuffer and immediately mark them as done to be dequeued.
The motivation for this patch is hardware assisted h.264 reordering support
in the coda driver. For high profile streams, the coda can hold back
out-of-order frames, causing a few mem2mem device runs in the beginning, that
don't produce any decompressed buffer at the v4l2 capture side. At the same
time, the last few frames can be decoded from the bitstream with mem2mem device
runs that don't need a new input buffer at the v4l2 output side. The decoder
command ioctl can be used to put the decoder into the ringbuffer draining
end-of-stream mode.

      [media] v4l2: remove deprecated current_norm support completely · ca371575
      由 Hans Verkuil 提交于 
      The use of current_norm to keep track of the current standard has been
deprecated for quite some time. Now that all drivers that were using it
have been converted to use g_std we can drop it from the core.
It was a bad idea to introduce this at the time: since it is a per-device
node field it didn't work for drivers that create multiple nodes, all sharing
the same tuner (e.g. video and vbi nodes, or a raw video node and a compressed
video node). In addition it was very surprising behavior that g_std was
implemented in the core. Often drivers implemented both g_std and current_norm,
because they didn't understand how it should be used.
Since the benefits were very limited (if they were there at all), it is better
to just drop it and require that drivers just implement g_std.

      [media] tveeprom: remove v4l2-chip-ident.h include · 33001010
      由 Hans Verkuil 提交于 
      Replace the V4L2_IDENT_* usage with tveeprom-specific defines. This header
is deprecated, so those defines shouldn't be used anymore.
The em28xx driver is the only one that uses the tveeprom audio_processor
field, so that has been updated to use the new tveeprom AUDPROC define.
