      V4L/DVB (4980): Fixes bug 7267: PAL/60 is not working · 315eb962
      由 Mauro Carvalho Chehab 提交于 
      On cx88 driver, sampling rate should be at chroma subcarrier freq (FSC).
However, driver were programming wrong values for PAL/60, PAL/Nc and
NTSC 4.43. This patch do the proper calculation. It also calculates
htotal, hdelay and hactive constants, according with the sampling
rate.
It is tested with PAL/60 by Piotr Maksymuk and Olivier. Also tested with
the already-supported standards.

Test is still required for PAL/Nc.

      V4L/DVB (4757): Cx88: determine whether or not to use external adc · f24546a9
      由 Michael Krufky 提交于 
      Some cx88-blackbird boards use an external adc, but not necessarily
for all inputs.  Thus, this needs to be configurable on the card level
for each input.
This patch allows for the usage of the external adc to be determined
by a bit setting in the cx88_input struct for cards based on the cx88
blackbird design.

      V4L/DVB (4676): Dynamic cx88 mpeg port management for HVR1300 MPEG2/DVB-T support. · 6c5be74c
      由 Steven Toth 提交于 
      A series of patches to change the cx88 framework to allow the
PCI mpeg port to be shared dynamically between different
types of drivers or applications. This patch changes the cx88-dvb
and cx88-blackbird drivers to become 'sub drivers' of a higher
single cx88-mpeg driver.
The cx88-mpeg driver is a superset of the previous cx88-mpeg/blackbird
drivers and now owns the IRQ. cx88-dvb/blackbird now become mini drivers,
registering themselves with cx88-mpeg through a standard interface with
callbacks.
Sub drivers request access to hardware via the cx88-mpeg driver. In turn
the cx88-mpeg driver determines whether the hardware is busy and accepts
or refuses the request, grant access using callbacks into the sub drivers.
The net effect is that you are no longer able to tamper with the mpeg port
from multiple different applications at the same time, potentially breaking
a live mpeg2 hardware encoding or dvb stream.
The mechanism extends to enable multiple dvb frontends to be registered
and share the single resource.

      V4L/DVB (3577): Cleanup audio input handling · 8bf2f8e7
      由 Hans Verkuil 提交于 
      Cleanup audio input handling in bttv and tvaudio:
- inputs were specified that were never used
- mute was handled as a special input which led to confusing code
- confusing naming made it difficult to see if the setting was for
  i2c or gpio.
The old audiochip.h input names moved to tvaudio.h. Currently this
is used both by tvaudio and msp3400 until the msp3400 implements the
new msp3400-specific inputs.
Detect in bttv the tvaudio and msp3400 i2c clients and use these
client pointers to set the inputs directly instead of broadcasting the
command.
Removed AUDC_SET_INPUT. Now replaced by VIDIOC_S_AUDIO. This will be
replaced again later by the new ROUTING commands.
Removed VIDIOC_G_AUDIO implementations in i2c drivers: this command is
a user level command and not to be used internally. It wasn't called at
all anyway.

      V4L/DVB (3516): Make video_buf more generic · c7b0ac05
      由 Mauro Carvalho Chehab 提交于 
      Video_buf were concerned to allow PCI devices to be used as
video capture devices. This patch extends video_buf features
by virtualizing pci-dependent functions and allowing other
type of devices to use it.
It is still DMA centric, although it may be used also by
devices that emulates scatter/gather behavior or a DMA device
