Subject: [PATCH v1 0/3] Add support for next gen eDP driver on sc7280

These patches add support for the next generation eDP driver on SnapDragon
with dpu support. The existing eDP driver cannot support the new eDP
hardware. So, to maintain backward compatibility, the older eDP driver is
moved to v200 folder and the new generation eDP driver is added in
the v510 folder.

These are baseline changes with which we can enable display. The new eDP
controller can also support additional features such as backlight control,
PSR etc. which will be enabled in subsequent patch series.

Summary of changes:
DPU driver interface to the new eDP v510 display driver.
New generation eDP controller and phy driver implementation.
A common interface to choose enable the required eDP driver.

Sankeerth Billakanti (3):
  drm/msm/edp: support multiple generations of edp hardware
  drm/msm/edp: add support for next gen edp
  drm/msm/disp/dpu1: add support for edp encoder
