3b94088707 V4L/DVB (8042): DVB-USB UMT-010 channel scan oops
In the umt-010 driver the struct umt_properties sets the number of URBs for
transfer to 20.  But in dvb-usb.h MAX_NO_URBS_FOR_DATA_STREAM is set to 10.

Not surprisingly this causes an oops for all devices which use the umt-010
chipset when they are inserted.

b4aba24186 V4L/DVB (7910): usb: input layer dependency fixes
testing of the -tip tree found the following build failures on
2.6.26-rc3:

  drivers/built-in.o: In function `ttusb_dec_disconnect':
  ttusb_dec.c:(.text+0xa2c95): undefined reference to `input_unregister_device'

  drivers/built-in.o: In function `dvb_usb_read_remote_control':
  dvb-usb-remote.c:(.text+0xa6a94): undefined reference to `input_event'

with this config:

  http://redhat.com/~mingo/misc/config-Tue_May_20_03_48_57_CEST_2008.bad

these are due to the media/dvb/usb layer having dependencies on INPUT
functionality, without having that spelled out in the Kconfig file.

this patch makes that dependency explicit (for the drivers affected),
which solves the build error.

755a18baad V4L/DVB (7851): Fix FW_LOADER depencency at v4l/dvb
Since:
1) FW_LOADER is defined as:

config FW_LOADER
        tristate "Userspace firmware loading support"
        depends on HOTPLUG

2) several V4L/DVB driver just selects it;

3) select is not smart enough to auto-select HOTPLUG, if select FW_LOADER.

So, All drivers that select FW_LOADER should also depend on HOTPLUG.

An easier solution (for the end-user perspective) would be to "select HOTPLUG".
However, live is not simple. This would cause recursive dependency issues like
this one:

drivers/usb/Kconfig:62:error: found recursive dependency: USB -> USB_OHCI_HCD
-> I2C -> MEDIA_TUNER -> MEDIA_TUNER_XC2028 -> HOTPLUG -> PCCARD -> PCMCIA ->

This patch fixes several issues on SCODE:

1) The extracting tool weren't generating the proper tags for SCODE. This
   has almost no effect, since those tags shouldn't be used;

2) DIBCOM52 were using a wrong IF. It should be 5200, instead of 5700;

3) seek_firmware were wanting an exact match for firmware type. This is
   wrong. As result, no SCODE firmware were loaded;

4) A few files were including the wrong file for seeking demod firmwares;

5) XC3028_FE_DEFAULT can be used, if user doesn't want to load a firmware.
   However, this weren't documentated. This feature require more testing.

78e92006f4 V4L/DVB (7538): Adds selectable adapter numbers as per module option
The adapter_nr module options can be used to allocate static adapter
numbers on a driver level. It avoids problems with changing DVB apapter
numbers after warm/cold boot or device unplugging and repluging.

Each driver holds DVB_MAX_ADAPTER long array of the preferred order of
adapter numbers.

options dvb-usb-dib0700 adapter_nr=7,6,5,4,3,2,1,0 would result in a
reversed allocation of adapter numbers.

With adapter_nr=2,5 it tries first to get adapter number 2 and 5. If
both are already in use it will allocate the lowest free adapter number.

58e6f95e61 V4L/DVB (7474): support key repeat with dib0700 ir receiver
This patch enables support for repeating last event when a key is holded
down with dib0700 devices. It works with rc5 and nec remotes.
It also fixes an annoying bug that floods kernel log with "Unknown key"
messages after each keypress. This happened because the driver was not
resetting infrared register after each poll so it kept polling last key
even if nothing was being pressed. Fixing this, (calling rc_setup after
each poll), permits to implement key repeat.

b412ba781a V4L/DVB (7399): Removes video_dev from tuner-xc2028 config struct
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.

5add9a6f3c 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.

702a67624e V4L/DVB (6655): Add support for MT352-based DViCO FusionHDTV DVB-T NANO devices
There are at least three variants of the DViCO FusionHDTV DVB-T NANO that
share the same USB device ID.  The first (ZL10353 w/ firmware in ROM) is
already supported; the latter two both require firmware and have either
an MT352 or ZL10353 demodulator, and have a different IR receiver from the
first.

This introduces a new identify_state that can tell the difference between a
"warm" device which is running the embedded firmware, and a "cold" device
that needs us to upload firmware to it before it will work.  We patch the
uploaded device ID (like we do for other bluebird devices) to make it easy
to identify the particular device variant when it reattaches.

NB: These devices use a different firmware file from previous bluebird
    devices.  You need a new firmware file to make this work.

firmware in ROM on the device.

Again, this is based on the great work of Mike Krufky with my modifications
to use the in-tree XC2028 driver.

aeb012bbf4 V4L/DVB (6649): Add support for the DViCO FusionHDTV Dual Digital 4
Add support for DViCO's Dual Digital 4 with xc3028 tuner, zl10353 DVB-T
demodulator and a new-style I2C IR remote control receiver.

This would not have been possible without the work of and advice from
Mike Krufky, who originally got the Dual Digital 4 and second-gen DVB-T
NANO devices working with the out-of-tree XC3028 driver.

I converted it to use the in-tree XC3028 driver (after making it suitable
for our use), and added the IR remote control support based on his advice.

NB: a firmware package is required to use this device.

a644e4a3e9 V4L/DVB (6627): CXUSB: handle write then read from different address
The path to perform a read immediately after a write was not checking that
the address being read from was the same as the one that was written.

Handling this case correctly should mean that we now can handle more than
two i2c messages at a time.

272479d7ab V4L/DVB (6626): CXUSB: support only-read i2c requests
Any i2c read request that was not immediately preceded by a write request was
incorrectly taking the write path.  Add the capability to handle individual
read requests.
