The ISIF generates VD0 interrupts even when writes are disabled.
Disabling the ISIF when no buffer is available is thus not be enough, we
need to handle the situation explicitly.

When VPDMA fetches or writes to an image buffer, the line stride must be a
multiple of 16 bytes. If it isn't, VPDMA HW will write/fetch until the next
16 byte boundry. This causes VPE to work incorrectly for source or destination
widths which don't satisfy the above alignment requirement.
In order to prevent this, we now make sure that when we set pix format for the
input and output buffers, the VPE source and destination image line strides are
16 byte aligned. Also, the motion vector buffers for the de-interlacer are
allocated in such a way that it ensures the same alignment.

The SpeedLink Vicious And Devine Laplace webcam is using an EM2765 bridge and
an OV2640 sensor. It has a built-in microphone (USB standard device class)
and provides 3 buttons (snapshot, illumination, mute) and 2 LEDs (capturing/mute
and illumination/flash). It is also equipped with an eeprom.
The device is available in two colors: white (1ae7:9003) and black (1ae7:9004).
For further details see http://linuxtv.org/wiki/index.php/VAD_Laplace.
Please note the following limitations that need to be addressed later:
- resolution limited to 640x480 (sensor supports 1600x1200)
- picture quality needs to be improved

This is similar to the Terratec H7. It works with the same az6007 firmware as
the former, however the drx-k firmware of the H7 will NOT work. Hence use
a different firmware name. The firmware does not need to exist as the one in
the eeprom is just fine as long as the h7 one doesn't get loaded, but maybe
some day someone wants to load it (the one from the h5 would work too).
Also since the config entry is now different anyway disable support for rc.
AFAIK the Technisat remote (TS35) is RC5 and the code (which a code comment
claims doesn't work anyway) only would handle NEC hence it's pointless creating
a device and polling it if we already know it can't work.
CI is untested.

Originally based on idea found on
http://www.linuxtv.org/wiki/index.php/TechniSat_CableStar_Combo_HD_CI claiming
only id needs to be added (but failed to mention it only worked because the
driver couldn't find the h7 drx-k firmware...).
