The board init gpio is 0x0, 0x200000 is from previously unloading with
antenna_switch = 1.

It needs firmware for the tda10046 and analog sound needs saa7134-alsa.

I have support for one more board and need to fix the first revision of
the Asus Tiger DVB-T hybrid. DVB-T currently hangs on the male radio
antenna input, also some small other stuff.

Please report any issues with this patch, the next are depending on this
one.

        SAA7134_TS_STOPPED
        SAA7134_TS_BUFF_DONE
        SAA7134_TS_STARTED

When buffer_setup is run we start the TS initialization: set SAA7134_TS_STOPPED.
When all buffers are prepared we write data into DMA register and set
SAA7134_TS_BUFF_DONE.
When the first buffer is active start TS and set SAA7134_TS_STARTED.
When ts_release is called stop TS and set SAA7134_TS_STOPPED.

622ecb3003 V4L/DVB (8625): saa7134: Add NEC prococol IR decoding capability
This patch adds the capability of decoding NEC protocol, received via GPIO18 line.
This GPIO port can trigger saa7134 IRQ.

A future improvement would be to make it a little more generic to work also
with GPIO16 line.

A pure IRQ code didn't work, since some delays were introduced on the tests we
did.

A possible approach would be to use polling at a rate of 2.5 ms or less. If a
new code were taken, a code similar to nec_task() could be used. However, this
would add an extra overhead to kernel, and will consume more power.

Due to that, we took an hybrid approach: an IRQ upper half to trigger when a
new key is received and a bottom half to convert pulse-distance into a keycode.

The bottom half is polling based, to improve performance. During the bottom
half proccess, GPIO18 IRQ line is disabled, preventing IRQ reentrancy and
improving performance a little bit.

video_exclusive_open (yuck!) and the last third required adding the

d53687d1d2 V4L/DVB (8496): saa7134: Copy tuner data earlier in init to avoid overwriting manual tuner type
When saa7134_board_init2 runs, it immediately overwrites the current value
(set earlier from module parameter) of tuner_type with the static values,
and then does autodetection. This patch moves the tuner_addr copy to earlier
in saa7134_initdev and removes the tuner_type copy from saa7134_board_init2.

Autodetection could still potentially change to the wrong tuner type, but it
is now possible to override the default type for the card again.

My card's tuner is configured with autodetection from eeprom, so I don't
need to manually set the tuner. I've checked that the autodetection still
works for my card.

a17898737e V4L/DVB (8108): Fix open/close race in saa7134
The saa7134 driver uses a (non-atomic) variable in an attempt to
only allow one opener of the device (how it deals with sending
the fd over unix sockets I don't know).

Unfortunately, the release function first decrements this variable,
and THEN goes on to disable more of the device. This allows for
a race where another opener of the device comes in after the decrement of
the variable, configures the hardware just to then see the hardware
be disabled by the rest of the release function.

This patch makes the release function use the same lock as the open
function to protect the hardware as well as the variable (which now
at least has some locking to protect it).

tda1004x: firmware upload failed

Sometimes, loading/unloading this firmware makes tda1004x to return an invalid
ID. However, there were no printk messages to help to identify what were the
cause for the error.

With this patch, it will now print:

Invalid tda1004x ID = 0xff. Can't proceed
saa7133[0]/dvb: failed to attach tda10046

83ee87a31d V4L/DVB (8026): Avoids an OOPS if dev struct can't be successfully recovered
On some alsa versions, it seems that snd_pcm_substream_chip(substream)
is returning a NULL pointer. This causes an OOPS, as reported by:

https://bugs.launchpad.net/ubuntu/+source/linux-ubuntu-modules-2.6.24/+bug/212271
https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/212960

This patch avoids the OOPS by not letting and open() succeed.

913f5fc209 V4L/DVB (8022): saa7134: fix race between opening and closing the device
decrementing dev->empress_users should be done as last action of ts_release,
because it sleeps and write access to dev->empress_started is not protected
in any way
(additionally closing thread could mute audio after opening thread unmuted it)

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 ->
USB_ARCH_HAS_HCD -> MOUSE_APPLETOUCH -> USB
