V4L/DVB (6430): Convert tuner-xc2028 driver to the newer hybrid approach This changeset converts tuner-xc2028 to the newer hybrid approach. It also prevents creating twice the xc3028 private struct by both DVB and V4L parts. Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>

V4L/DVB (6646): xc2028: rework firmware (re)loading process Define a list of valid "firmware types" for each combination of BASE, DTV and SCODEs. By masking the appropriate firmware bits off we can just use one "type" for the firmware searching and also flag when we are looking for a BASE, DTV or SCODE type firmware. This makes it much easier to track if we need to change device modes or flash an individual firmware part. Add a structure to remember what firmware properties we have. This contains the currently loaded/wanted base firmware (type), video std (id), video std requested (std_req), scode file and number in use. Incorporate said structure into the tuner private data. When checking whether the current firmware needs to be reloaded, first figure out exactly what "type" of firmware we want (base, std and scode), and then proceed to load the appropriate matching base, std-specific and scode records iff there are any changes required. This removes guesswork from the process because we no longer need to individually code a check for every tuning parameter's interactions.

V4L/DVB (6659): Convert MTS to bitfield Xc2028.3028 has two type of firmwares: audio-standard specific ones and baseband MTS firmwares. MTS firmwares provide stereo decoding for 6 MHz BTSC/EIAJ and for monoaural audio decoding on 8 MHz firmwares. It seems that the option to use MTS or a standard-specific audio decoding depends on the way xc2028/3028 is connected. Instead of wasting 32 (or 64 bits) to signalize if the driver needs to use MTS firmware, this patch converts it to a bitfield that can be shared with other proprieties of xc2028/3028.

V4L/DVB (6660): Allow fully configuring xc3028 during xc2028_attach xc3028 can be used on some DTV only designs (for example, DVB-S boards). Before this patch, a DTV only board would need to call set_tuner_config callback. This patch allows to optionally pass a xc3028_ctrl parameter, via xc3028_config struct, fully initializing the driver for DTV. Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
