* V4L/DVB (7399): Removes video_dev from tuner-xc2028 config structMauro Carvalho Chehab2008-04-24
| | | | | | | | | | | | | | | The video_dev parameter, on tuner-xc2028 were used to pass i2c private data to tuner_callback. Since the driver already have a pointer to i2c_adap->algo_data, uses this instead. This parameter were used also as a magic number to idenfity if two drivers are trying to register the same xc3028 tuner. This occurs with boards with DVB support, where both DVB and V4L drivers will share the same tuner. Instead of using the algo_data as a private number, after this patch, the driver will use i2c_adap->dev, with seems more consistent. Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
* V4L/DVB (7260): tuner-xc3028: Don't check return code for clock resetMauro Carvalho Chehab2008-04-24
| | | | | | | | | Only tm6000 needs to be aware when a frequency is being changed. This seems to improve channel change detection. Other bridges don't need this. So, better to discard any errors if this fails, and proceed changing the channels. Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>

* V4L/DVB (6875): tuner-xc2028: ATSC requires 1.75 MHz tuning offsetMichael Krufky2008-01-25
| | | | | | | | | | | | | | | | | | | | | | In my testing yesterday, I was using a scan file tailored specifically for a unique test situation -- As it turns out, this scan file was bad, and I will use the one included inside dvb-apps for testing for now on. I've tested with other ATSC tuners just to confirm, using: us-ATSC-center-frequencies-8VSB Anyhow, as it turns out, the tuner-xc2028 *does* require a tuning offset for ATSC. Even though the linux-dvb api passes in center frequencies from userspace, apparantly the xceive firmware is already factoring in the tuning offset to center. In order to make the device function using the same scan files / channels.conf configurations as other atsc devices, we must offset by 1.75 MHz.

* V4L/DVB (6855): xc2028: select DTV78 firmware if tuning 7MHz VHF / 8MHz UHFChris Pascoe2008-01-25
| | | | | | | | | | | | | It seems that the DTV78 firmware is intended for use in locations where VHF channels have 7MHz bandwidth and UHF channels have 8MHz bandwidth. If we switch to DTV78 firmware when we detect this condition, we can avoid firmware reloads when switching between VHF and UHF transponders. Place the state for this in the control structure so that card drivers can hint to us to use DTV78 firmware from the first tuning attempt.

* V4L/DVB (6853): xc2028: check HAS_IF flag against tableChris Pascoe2008-01-25
| | | | | | | | | | When searching for the right S-Code table to load, check the HAS_IF flag against the firmware we are checking instead of against the the "type" requested. We already ignore the scode type requested if the caller passed an int_freq; this makes the search by frequency consistent with that behaviour.

* V4L/DVB (6676): Improve s-code supportMauro Carvalho Chehab2008-01-25
| | | | | | | | | | | | | s-code tables are related to IF frequency used for video demodulation. The s-codes for analog are automatically loaded, according with video standard. However, for digital, they will depend on the IF of the demoduler chip. IF of the demoduler. Before this patch, only a few IF's where possible to use.

| | | | | | | | | | | Since check_firmware is called via analog or digital set freq routines, move type selection to those routines.

* V4L/DVB (6661): Remove firmware reload hack for analogMauro Carvalho Chehab2008-01-25
| | | | | | | | | | | | On some cases, xc2028/xc3028 wents into "turn off" mode. It seems that this happens when very weak signals are tuned. To solve this, specific standard reaload were done previously. Christopher patches changed this behavior to a complete firmware reload. This patch removes the hack. A much cleaner solution for this trouble is just to sent a xc2028/3028 software reset. Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
* V4L/DVB (6660): Allow fully configuring xc3028 during xc2028_attachMauro Carvalho Chehab2008-01-25
| | | | | | | | | | 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>
* V4L/DVB (6659): Convert MTS to bitfieldMauro Carvalho Chehab2008-01-25
| | | | | | | | | | | | | | | 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 (6646): xc2028: rework firmware (re)loading processChris Pascoe2008-01-25
| | | | | | | | | | | | | | | | | | | | | | | | | 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.
