Darron Broad 2f3af9e64d V4L/DVB (9226): MFE: cx88: Reset cx22702 on hvr-3000/4000
The cx22702 is now always reset on module load. Prior to
this the cx22702 was not found on i2c scan without a
full reset.

Darron Broad 92abe9ee37 V4L/DVB (9223): MFE: Fix a number of bugs and some tidying up
A number of reference to videobuf_dvb_get_frontend used an invalid
index. This has been fixed.

The section for the HVR3000 in advise_acquire was redundant as
the same logic is used on the HVR4000. This has been removed
and both cards now use the same function.

A number of small errors and whitespace errors are also fixed.

Steven Toth 363c35fc44 V4L/DVB (9222): S2API: Add Multiple-frontend on a single adapter support.
A detailed description from the original patches 2 years ago:

"The WinTV-HVR3000 has a single transport bus which is shared between
a DVB-T and DVB-S modulator. These patches build on the bus acquisition
cx88 work from a few weeks ago to add support for this.

So to applications the HVR3000 looks like this:
/dev/dvb/adapter0/fe0 (cx24123 DVB-S demod)
/dev/dvb/adapter0/fe1 (cx22702 DVB-T demod)

Additional boards continue as before, eg:
/dev/dvb/adapter1/fe0 (lgdt3302 ATSC demod)

The basic change is removing the single instance of the videobuf_dvb in
cx8802_dev and saa7134_dev(?) and replacing it with a list and some
supporting functions.

*NOTE* This branch was taken before v4l-dvb was closed for 2.6.19 so
two or three current cx88 patches appear to be reversed by this tree,
this will be cleaned up in the near future. The patches missing change
the mutex handing to core->lock, fix an enumeration problem."

It should be recognised that a number of people have been maintaining
this patchset. Significant levels of Kudos to everyone one involved,
including but not limited to:

Darron Broad
Fabio M. Di Nitto
Carlo Scarfoglio
Hans Werner

Without the work of these people, and countless others, my two year old
patches would of died on the Mercurial linuxtv.org vine a long time
ago.

TODO: Revise these patches a little further so that the need for
demux1 and dvr0 is optional, not mandatory on the HVR3000.

HISTORY (darron):
This is the last update to MFE prepared by Hans which is based
upon the `scratchpad' diff created by Carlo.
All MFE work prior to that point must be attributed to Fabio
who ported and maintained Steve's original patch up to that
time.

Tim Farrington 19c309e383 V4L/DVB (9135): cx88 Dvico FusionHDTV Pro
Well, one thing you encouraged me to do was re-test some of my cards
which contained the xc3028-zarlink combo.

Which led me to test a Dvico FusionHDTV Pro.

Almost a year ago, Chris Pascoe did a patch for this which can be found
at his ~pascoe/xc-test at Linuxtv.
This worked very well, however that was using his version of firmware.

Alas, someone attempted to use this and patch v4l-dvb, and messed it up.
So I've fixed it.
I enclose the patch against today's tree (containing your latest
tuner-xc2028.c patch).

The card now works very well, well with DVB-T anyway.

Stéphane Voltz 3f6014fc77 V4L/DVB (9066): Pinnacle Hybrid PCTV Pro (pctv310c) DVB-T support
This patch against latest mercurial makes DVB-T working on Pinnacle
Hybrid PCTV Pro (pctv310c).

In cx88-dvb.c, a specific zl10353_config is created with the if2
inferred from the old comment in the currently used config. It is then
used for attach, and i2c_gate_ctrl is set to NULL.

The entry in cx88-cards.c is modified with GPIO gathered from windows
with regspy, and DVB enabled. The frontend is set to
XC3028_FE_ZARLINK456 to match the zl10353_config.

It is working great with the freeview channels I can receive.

Mauro Carvalho Chehab 4bf1226a70 V4L/DVB (7749): cx88: fix tuner setup
Tuner setup were happening during i2c attach callback. This means that it would
happen on two conditions:

	1) if tuner module weren't load, it will happen at request_module("tuner");

	2) if tuner is not compiled as a module, or it is already loaded
	   (for example, on setups with more than one tuner), it will happen
	   when cx88 registers I2C bus.

Due to that, if tuner were loaded, tuner setup will happen _before_ reading
the proper values at tuner eeprom. Since set_addr refuses to change for a tuner
that were previously defined (except if the tuner_addr is set), this were making
eeprom tuner detection useless.

This patch removes tuner type setup from cx88-i2c, moving it to the proper
place, after taking eeprom into account.

Mauro Carvalho Chehab 99e09eac25 V4L/DVB (7448): Add support for Kworld ATSC 120
This board has a s5h1409 demod, plus a xc30x8 tuner (probably, xc3018).

This patch adds proper support for radio, video, s-video, composite and ATSC.
However, support for radio and video depends on having s5h1409 i2c gate open,
otherwise, xc30x8 chip won't be visible.

For a better support, some rework is needed on cx88 driver, to allow adding
xc30x8 to i2c bus without sending i2c 0 byte reading to 0xc2 address.

Thanks to Vanessa Ezekowitz <vanessaezekowitz@gmail.com> for helping to figure
out the proper parameters for s5h1409 and the GPIO pins used by each
configuration.

Trent Piepho 5772f81326 V4L/DVB (6023): cx88: Clean up some ugly and inconsistent printk()s
Get rid of the "CORE" prefix from cx88 printks.  It was only used a few times,
and it makes it look like they're coming from the kernel core or something.

Fix the message, "TV tuner 60 at 0x1fe, Radio tuner -1 at 0x1fe", by adding a
"cx88[0]" prefix to be consistent, and to keep people who grep their dmesg
output for cx88 from missing it.  Get rid of the addresses, which are always
wrong.  The addresses are always set to -1, but because it's an unsigned 8-bit
value, the left shift converts it to the nonsense address 0x1fe.

In the cx8802 driver, some cut and pasted code prefixed lines with "CORE
cx88[0]:", which has been changed to "cx88[0]/2:" like the other printks from
the cx8802 driver.

Also fix some ugly printks in the cx8802 driver that used __FUNCTION__ for
KERN_INFO and KERN_ERR messages.

The changed printks in cx88-mpeg.c also needed lots of whitespace and
80-column fixes.

A bunch of misc changes in cx88-dvb.c and cx88-video.c to add message levels
or a consistent "cx88[?]/2" or "cx88[?]/0" prefix.

- Module parameters tuner, radio, card, and latency move to cx88-cards.c
- cx88_boards is made static
- cx88_subids is made static and const
- cx88_bcount is eliminated
- cx88_idcount is eliminated
- cx88_card_list() is made static
- cx88_card_setup_pre_i2c() is made static
- cx88_card_setup() is made static
- cx88_pci_quirks() is moved from cx88-core to cx88-cards
  The function argument "char *name" is made const too
- get_ressources() is moved from cx88-core to cx88-cards, and renamed to
  cx88_get_resources()
- The code to allocate and initialize the core state struct and the chip is
  moved out of cx88-core.c:cx88_get_core() and into a new function in
  cx88-cards.c, cx88_core_create().  This makes both functions simpler.

Trent Piepho 6a59d64c5c V4L/DVB (6021): cx88: Copy board information into card state
The cx88 driver state stored the ID of the board type in core->board.  Every
time the driver need to get some information about the board configuration, it
uses the board number as an index into board configuration array.

This patch changes it so that the board number is in core->boardnr, and
core->board is a copy of the board configuration information.  This allows
access to board information without the extra indirection.  e.g.
cx88_boards[core->board].mpeg becomes core->board.mpeg.

This has a number of advantages:
- The code is simpler to write.

- It compiles to be smaller and faster, without needing the extra array lookup
  to get at the board information.

- The cx88_boards array no longer needs to be exported to all cx88 modules.

- The boards array can be made const

- It should be possible to avoid keeping the (large) cx88_boards array around
  after the module is loaded.

- If module parameters or eeprom info override some board configuration
  setting, it's not necessary to modify the boards array, which would
  affect all boards of the same type.

Trent Piepho 19dc74b7c5 V4L/DVB (5975): cx88: Wrong values used for HD-3000 radio mode
After some tedious work with a logic probe and a magnifying glass, I've
determined that GPIO 7 is used to switch between the DTT7612's Sound 4.5 MHz
IF output on pin 12 and the FM 10.7MHz If output on pin 11.  GPIO 2 is used to
switch the card's analog sound output from from the analog input connector to
the CX23883's audio DACs.

So, in radio mode GPIO2 = 1 and GPIO7 = 0.

Add some comments about how the HD-3000's GPIOs are connected.

Delete the vmux setting for the radio, as vmux doesn't apply to radio mode.
Also delete the lines setting unused gpio words to zero; it's not necessary as
0 is the default value for uninitialized fields.
