Compro VideoMate uses an external audio DSP chip, controlled via tvaudio
module (tda9874a). This patch improves em28xx infrastructure to support

As reported by Vitaly Wool <vital@embeddedalley.com>:

c744dff260 V4L/DVB (10519): em28xx: Fix for em28xx audio startup
Essentially if a snd_em28xx_capture_trigger() stop followed by a snd_em28xx_capture_trigger() start would not yield any
data because there was some logic put in with an adev->shutdown variable which did not seem warranted in my humble opinion.
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.

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.

Refactor the em28xx IR support based on the em2860/em2880 and em2874
datasheets.

Tested on the HVR-950 (em2883), Pinnacle 800e (em2883), Pinnacle 80e (em2874)
using the remote controls that came with those products.

a924a499ad V4L/DVB (9607): em28xx: Properly implement poll support for IR's
The first em28xx were based on i2c IR's. However, some newer designs
are coming with a polling-based IR. Those are done by reading a register
set at em28xx.

This patch adds core polling support for those devices. Later patches will
add support for some device-specific IR's.

This patch adds the same basic IR polling code used by bttv, cx88 and saa7134, and
shares the common getkey masks defined at ir-common.

864ec0b7a0 V4L/DVB (9590): Add registration for Pinnacle 80e ATSC tuner
Add registration for Pinnacle 80e ATSC tuner

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.

24a613e4b0 V4L/DVB (9588): Don't load em28xx audio module for digital-only devices
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)

6a1acc3bc5 V4L/DVB (9584): Support different GPIO/GPO registers for newer devices
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).

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

600bd7f0ed V4L/DVB (9583): Remember chip id of devices at initialization
When setting up the device, remember the chip id, so we can control behavior
in the future without having to read the register continuously.
