This patch series add support for the TI VIP video capture engine.
VIP stands for Video Input Port, it can be found on devices such as
DRA7xx and provides a parallel interface to a video source such as
a sensor or TV decoder. Each VIP can support two inputs (slices) and
a SoC can be configured with a variable number of VIP's.
Each slice can support two ports each connected to its own
sub-device.
Here is the output of v4l2-compliance against this driver:
# v4l2-compliance -s -d 1
v4l2-compliance SHA: not available, 32 bits
