[PATCH v7 0/6] Add support for DisplayPort driver on SnapDragon

[Tanmay Shah]

These patches add Display-Port driver on SnapDragon/msm hardware.
This series also contains device-tree bindings for msm DP driver.
It also contains Makefile and Kconfig changes to compile msm DP driver.

The block diagram of DP driver is shown below:
