Contrary to my earlier belief, the ov7670 is not actually an SMBUS device, though it will pretend to be one if it's in a good mood. Unfortunately, it's rarely in a good mood, especially on the XO 1.5. So use low-level i2c I/O instead. Signed-off-by:

Also provide for a longer delay after reset - the XO 1.5 needs it. Signed-off-by:

Add support for design which has an em2863/tvp5150 and uses the standard empia USB ID. In Sander's case, it was branded as an "Eminent model EM3705" Thanks to Sander Van Ginkel for testing and help debugging the support.

It seems that I merged a wrong version of the patch or that changeset 4d770eeb926d0bc44c0bd68d051d3d2a5568ef41 got mangled somehow: It were missed the #else to avoid compilation troubles. Signed-off-by: -

Add the ability to use the v4l2_ctrl_query_fill() function for the newly introduced chroma gain control. Also, make use of the centralized function by the one caller. This work was sponsored by EyeMagnet Limited. Signed-off-by:

Introduce a new control for modifying the chroma gain. This allows for user intervention in abnormal signal conditions cases where the decoder's chroma AGC cannot compensate and the value needs to be adjusted manually. This work was sponsored by EyeMagnet Limited. Signed-off-by:

This patch enables the anti-alias filter, which was originally enabled for the saa7113, but the saa7115_init_misc was trampling the value. Without this patch, there would be visible vertical bands in the chroma. Thanks to Andy Walls for helping test this change against other ivtv products. This work was sponsored by EyeMagnet Limited.

Rework the logic for tracking the amount of data copied to the VBI buffer, to address problem found where the video lines are several bytes shifted to the right (and the leading pixels in the first line rendered are garbage). This would occur because the copy function would advance the pointer when detecting headers, but the caller would not adjust the length actually copied. This work was sponsored by EyeMagnet Limited.

It turns up we can reduce the starting line for the active area, which results in more data being captured when under PAL (while the full VBI capture window still stays properly encoded). This work was sponsored by EyeMagnet Limited. Signed-off-by:

Increase the packets per URB count from 40 to 64. I suspect that whoever was looking at the usbsnoop captures saw "0x40" packets and mistook it for "40". As a result of this change, I can see a 25% reduction in the number of interrupts generated via powertop. This work was sponsored by EyeMagnet Limited. Signed-off-by:
