Hi All,
Here is my next round of atomisp work.
The atomisp wants some extra padding for processing in the data it receives
from the sensor. E.g. For 1600x1200 it wants to receive 1616x1216 from
the sensor. Currently the private sensor driver copies it uses give it
e.g. 1616x1216 and the ISP2 code then substracts 16 before reporting
the resolution to userspace.
This patch series adds support for the v4l2 selections API and specifically
the crop target so that atomisp can request the extra padding from standard
v4l2 sensor drivers. This is implemented / tested with the atomisp_ov2680
driver.
Besides that there is the usual cleanups / prep work.
With the padding solved, the last bit of private atomisp sensor API is
gone now. So we can start working on getting rid of its private sensor
driver copies.
As mentioned in the updated TODO file the next step is to port
various improvements from the atomisp_ov2680 private sensor driver
to the generic ov2680 sensor driver (such as the selections support)
and then switch to the generic ov2680 sensor driver.
Regards,
Hans
