Subject[Patch 0/2] media: ti-vpe: Add the VIP driver
Date
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
