Devin Heitmueller e2a1b79f7d V4L/DVB (11927): em28xx: provide module option to disable USB speed check
Add an em28xx module option that allows a user to override the USB speed check.
Intended for advanced users who understand the consequences of trying to use
the device with a 12Mbps bus.

Devin Heitmueller 3ed58baf5d V4L/DVB (11925): em28xx: Add support for the K-World 2800d
Make the KWorld 2800d work properly.  In this case, that means making the
profile more generic so that it works for both the Pointnix Intra-Oral USB
camera and the KWorld device.

The device provides the audio through a pass-thru cable, so we don't need
an actual audio capture profile (neither the K-World device nor the Pointnix
have an onboard audio decoder).

Thanks to Paul Thomas for providing sample hardware.

Devin Heitmueller 64a00b43e6 V4L/DVB (11923): em28xx: Don't let device work unless connected to a high speed USB port
The em28xx basically just doesn't work at 12 Mbps.  The isoc pipe needs
nearly 200 Mbps for analog support, so users would see garbage video, and on
the DVB/ATSC side scanning is likely to work but if the user tried to tune it
would certainly appear to have failed.

It's better to fail explicity up front and tell the user to plug into a USB 2.0
port, than to let the driver load and the user have weird problems with tuning
and garbage video.

Robert Krakora 75c74d1c78 V4L/DVB (11896): em28xx: Fix for Slow Memory Leak
Test Code:  (Provided by Douglas)

v4l-dvb/v4l2-apps/test/stress-buffer.c

The audio DMA area was never being freed and would slowly leak over
time as the v4l device was opened and closed by an application.

Thanks again to Douglas for generating the test code to help locate
memory leaks!!!

Jean Delvare c668f32dca V4L/DVB (11844): ir-kbd-i2c: Switch to the new-style device binding model
Let card drivers probe for IR receiver devices and instantiate them if
found. Ultimately it would be better if we could stop probing
completely, but I suspect this won't be possible for all card types.

There's certainly room for cleanups. For example, some drivers are
sharing I2C adapter IDs, so they also had to share the list of I2C
addresses being probed for an IR receiver. Now that each driver
explicitly says which addresses should be probed, maybe some addresses
can be dropped from some drivers.

Also, the special cases in saa7134-i2c should probably be handled on a
per-board basis. This would be more efficient and less risky than always
probing extra addresses on all boards. I'll give it a try later.

In the standard device driver binding model, the name field of
struct i2c_client is used to match devices to their drivers, so we
must stop using it for internal purposes. Define a separate field
in struct IR_i2c as a replacement, and use it.

Devin Heitmueller d18e2fda71 V4L/DVB (11810): em28xx: properly set packet size based on the device's eeprom configuration.
The em28xx actually has a register that tells the driver what the maximum
packet size is (based on a value programmed into the eeprom).  Make use of
that register instead of assuming a hardcoded value of 564 (since 564 is not
correct for devices that do QAM such as the KWorld 340u).

Note that for now the em2874 code isn't there, falling back to the 564 value,
however this is not a problem since there are not any em2874 based devices in
the current v4l-dvb tree).

Thanks to Jarod Wilson for detecting the initial problem and figuring out that
the isoc configuration was wrong for his device.

Essentially if a snd_em28xx_capture_trigger() stop followed by a snd_em28xx_capture_trigger() start would not yield any

It would cause snd_em28xx_capture_trigger start never to start up the audio stream until the device was closed and
reopened again. Upon re-opening the device adev->shutdown is reset and audio data would again flow.

Nicola Soranzo 7662b00c37 V4L/DVB (10659): em28xx: register device to soundcard for sysfs
As explained in "Writing an ALSA driver" (T. Iwai), audio drivers should
set the struct device for the card before registering the card instance.
This will add the correct /sys/class/sound/cardN/device symlink, so HAL
can see the device and ConsoleKit sets its ACL permissions for the
logged-in user.

For em28xx audio capture cards found e.g. in Hauppauge WinTV-HVR-900 (R2),
this patch fixes errors like:

ALSA lib pcm_hw.c:1429:(_snd_pcm_hw_open) Invalid value for card

 =======================

The culprit in the trace is snd_pcm_action() which invokes a spin lock
which disables pre-emption which disables an IRQ which causes the
__might_sleep() function to fail the irqs_disabled() test.  Since
pre-emption is enabled then it is safe to de-allocate the memory if
you first unlink each URB.  In this instance you are safe since
pre-emption is disabled.  If pre-emption and irqs are not disabled then
call usb_kill_urb(), else call usb_unlink_urb().

In some cases, introducing one of these functions is not possible, and it

USB_ENDPOINT_XFER_BULK
USB_ENDPOINT_XFER_CONTROL
USB_ENDPOINT_XFER_INT
USB_ENDPOINT_XFER_ISOC

Correct problem introduced during the board refactoring where the XCLK
frequency would get zero'd out.  The sequence of events was as follows:

em28xx_pre_card_setup() called em28xx_set_model()
em28xx_set_model() would memcpy to dev->board configuration
em28xx_pre_card_setup() would set the dev->board.xclk if not set
em28xx_pre_card_setup() would set the XCLK register based on dev->board.xclk
...
em28xx_card_setup() would call em28xx_set_model()
em28xx_set_model() would memcpy to dev->board configuration (clearing out
 value of dev->board.xclk set in em28xx_pre_card_setup)
...
em28xx_audio_analog_set() sets the XCLK register based on dev->board.xclk
 (which now contains zero)

The change sets the default XCLK and I2C Clock fields in the board definition
inside of em28xx_set_model() so that subsequent calls do not cause the
values to be overwritten.

em28xx devices generally get hot when xc3028 tuner is powered on. This
patch solves this by turning power off when the device is not used, at the
expense of having a higher load time, when calling a TV application.

Since firmware load happens on 1 or 2 seconds on most devices, this is not a pain.

Also, it helps to save the planet by saving some power :)

Mauro Carvalho Chehab a2070c6654 V4L/DVB (9747): em28xx: Properly handles XCLK and I2C speed
The previous patches removed XCLK and I2C magic. Now, we finally know
what those registers do. Also, only a very few cards need different
setups for those.

Instead of keeping the setups for those values inside the per-device
hack magic switch, move the uncommon values to the board-specific
struct, and have a common setup for all other boards.

So, almost 100 lines of hacking magic were removed.

A co-lateral effect of this patch is that it also fixes a bug at em28xx-core, where xclk
were set, without taking any care about not overriding a previous xclk setup.

Register the em2874 based Pinnacle 80e device.  Note that support for this
device also requires the new drx-j driver (which is not available yet)

Thanks for Ray Lu from Empia for providing the em2874 datasheet.
Thanks to Joerg Schindler from Pinnacle for providing sample hardware.
Thanks to Rainer Miethling from Pinnacle for providing engineering support.

Properly support capture start on em2874

The transport stream enable register moved in the em2874, so make it work
properly.

Rework the logic so that the em28xx-alsa module does not get loaded for devices
that don't support analog audio (such as the em2874)

Empia moved around their endpoint configuration in newer chips, so accommodate
the changes

Fix case where we could end up dereferencing a NULL pointer if dev->vdev or
dev->vbi_dev were not set properly.

Devin Heitmueller a527c9f827 V4L/DVB (9585): Skip reading eeprom in newer Empia devices
Empia switched to a 16-bit addressable eeprom in newer devices.  While we
could certainly write a routine to read the eeprom, there is nothing of use
in there that cannot be accessed through registers, and there is the risk that
we could corrupt the eeprom (since a 16-bit read call is interpreted as a
write call by 8-bit eeproms).  So just be safe and bail out of the function.

Thanks for Ray Lu from Empia for providing the em2874 datasheet.

Empia moved the location of the GPIO/GPO registers in newer devices.  Add the
ability to specify the relocated registers (including caching of register
contents).

When setting up the device, remember the chip id, so we can control behavior
in the future without having to read the register continuously.
