[media] v4l: Load I2C modules based on modalias

When creating a new sub-device, The V4L I2C subdev API has historically
required drivers to pass the name of the module that implements support
for the I2C device.

I2C modules can be loaded based on modaliases instead of the module
name. As the I2C device type name is already available to the
v4l2_i2c_new_subdev* functions, make the module name argument optional
and create a modalias based on the type name when no module name is
provided.

All in-tree drivers call those functions with a non-NULL module name
argument, this change is thus harmless.

[media] Support for Elgato Video Capture

This patch allows this device successfully to show video, at least from
its composite input.

I have no information about the true hardware contents of this device and so
this patch is based solely on fiddling with things until it worked. The
chip appears to be em2860, and the closest device with equivalent inputs
is the Typhoon DVD Maker. Copying the settings for that device appears
to do the trick. That's what this patch does.

[media] msp3400: fix mute audio regression

The switch to the new control framework caused a regression where the audio was
no longer unmuted after the carrier scan finished.

The original code attempted to set the volume control to its current value in
order to have the set-volume control code to be called that handles the volume
and muting. However, the framework will not call that code unless the new volume
value is different from the old.

Instead we now call msp_s_ctrl directly.

It is a bit of a hack: we really need a v4l2_ctrl_refresh_ctrl function for this
(or something along those lines).

Thanks to Andy Walls for bisecting this and to Shane Shrybman for reporting it!

[media] SoC Camera: add driver for OV6650 sensor

This patch provides a V4L2 SoC Camera driver for OV6650 camera sensor, found
on OMAP1 SoC based Amstrad Delta videophone.

Since I have no experience with camera sensors, and the sensor documentation I
was able to find was not very comprehensive, I left most settings at their
default (reset) values, except for:
- those required for proper mediabus parameters and picture geometry and
  format setup,
- those used by controls.
Resulting picture quality may be far from perfect, but better than nothing.

In order to be able to get / set the sensor frame rate from userspace, I
decided to provide two not yet SoC camera supported operations, g_parm and
s_parm. These can be used after applying patch 4/6 from this series,
"SoC Camera: add support for g_parm / s_parm operations".

[media] SoC Camera: add driver for OMAP1 camera interface

This is a V4L2 driver for TI OMAP1 SoC camera interface.

Both videobuf-dma versions are supported, contig and sg, selectable with a
module option. The former uses less processing power, but often fails to
allocate contignuous buffer memory. The latter is free of this problem, but
generates tens of DMA interrupts per frame. If contig memory allocation ever
fails, the driver falls back to sg automatically on next open, but still can
be switched back to contig manually. Both paths work stable for me, even
under heavy load, on my OMAP1510 based Amstrad Delta videophone, that is the
oldest, least powerfull OMAP1 implementation.

The interface generally works in pass-through mode. Since input data byte
endianess can be swapped, it provides up to two v4l2 pixel formats per each of
several soc_mbus formats that have their swapped endian counterparts.

Boards using this driver can provide it with the following platform data:
- if and what freqency clock is expected by an on-board camera sensor,
- what is the maximum pixel clock that should be accepted from the sensor,
- what is the polarity of the sensor provided pixel clock,
- if the interface GPIO line is connected to a sensor reset/powerdown input
  and what is the input polarity.

Created and tested against linux-2.6.36-rc5 on Amstrad Delta.
