9c12224a60 V4L/DVB (6079): Cleanup: remove linux/moduleparam.h from drivers/media files
Since at least kernel 2.6.12-rc2, module.h includes moduleparm.h. This
patch removes all occurences of moduleparm.h from drivers/media files.

6d77444aca V4L/DVB (6027): Get rid of an ill-behaved msleep in i2c write
Configuring the OLPC camera requires something over 150 register
writes.  Unfortunately, querying the CAFE i2c controller too
soon after a write causes the hardware to flake.  The problem had
been "solved" with an msleep() call, but, between the number of
registers and how msleep() behaves, that resulted in a 3-second
delay on camera initialization.  Instead, we hand-code a wait for
the completion interrupt which avoids reading the status registers.

edd75ede2d V4L/DVB (5691): Ov7670: reset clkrc in rgb565 mode
A bug in the ov7670 sensor causes it to introduce noise unless the CLKRC
register is rewritten *after* setting the image mode.  Naturally,
resetting CLKRC in this way will cause other modes to fail.  So
carefully poke the register only when indicated.

7f7b12f09b V4L/DVB (5468): Don't mirror ov7670 images by default
Don't mirror ov7670 images by default.

The ov7670 sensor driver sets the mirror bit by default, which is not
the desired mode.  OLPC has been running with this patch for a while.

3434eb7e14 V4L/DVB (5306): Add support for VIDIOC_G_CHIP_IDENT
VIDIOC_G_CHIP_IDENT improves debugging of card problems: it can be
used to detect which chips are on the board and based on that information
selected register dumps can be made, making it easy to debug complicated
media chips containing tens or hundreds of registers.
This ioctl replaces the internal VIDIOC_INT_G_CHIP_IDENT ioctl.
