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...

It is here for v5. https://patchwork.freedesktop.org/series/74312/


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.

Ok Thanks.

Can you include a changelog in the cover letter too so we know what has
changed between versions of the patchset?

Sure.

Chandan Uddaraju (4):
  dt-bindings: msm/dp: add bindings of DP/DP-PLL driver for Snapdragon
  drm: add constant N value in helper file
  drm/msm/dp: add displayPort driver support
  drm/msm/dp: add support for DP PLL driver

Jeykumar Sankaran (1):
  drm/msm/dpu: add display port support in DPU
