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 supports two ports each connected to its own
sub-device.
