Subject: [PATCH V4 0/4] Add support for TI VIP

This patch series adds support for the TI VIP. 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.

Changelog:
Changes in v4:
Krzysztof:
- Squash patches 1,2,3 of v3 into patch 1 of v4
- Fix title in DT binding
- Drop configuration parameters from DT binding
- Remove redundant remote-endpoint in DT binding
- Have one contiguous address space as defined by TRM.
- Make example complete by adding endpoints to all VIP instances
- Since we now have one contiguous address space, declare offsets
  of scalar, color space converter and vpdma in vip.h
- Also change the driver to use these offsets instead of
  using sc.c and csc.c libraries
- Since we now have one contiguous address space, we cannot use
  VPDMA helpers. Hence export vpdma_load_firmware() to load
  VPDMA firmware (Patch 2/4)
