[Freedreno] [DPU PATCH v4 0/5] Add support for DisplayPort driver on SnapDragon.

[Vara Reddy]

These patches add support for Display-Port driver on SnapDragon hardware. It adds
DP driver and DP PLL driver files along with the needed device-tree bindings.

The block diagram of DP driver is shown below:
