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:

I've never seen a block diagram for a driver before...
These patches have dependency on clock driver changes mentioned below: https://patchwork.kernel.org/patch/11245895/ https://patchwork.kernel.org/cover/11069083/
These are merged right? Don't need to include this if it's already merged.
Can you include a changelog in the cover letter too so we know what has changed between versions of the patchset?
