V4L/DVB (10755): cx18: Convert the integrated A/V decoder core interface to a v4l2_subdev
This is the next step in converting the cx18 driver to use the v4l2_device/ v4l2_subdevice framework. This is a straightforward conversion of the cx18_av_*[ch] files. It compiles, but leaves the driver in an unlinkable state at the moment. Note, the cx18 integrated A/V digitizer will now make a host match at address 1, as far as v4l2-dbg is concerned. That means it identifies itself as a separate "chip", and acts as an alias to the integrated A/V decoder registers that are also available with the host match at address 0. Signed-off-by: Andy Walls <awalls@radix.net> [mchehab@redhat.com: fix merge conflicts due to the removal of v4l2_ctrl_query_fill_std()] Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
