Subject: [PATCH v2 0/3] drm/msm/dp: Rework the eDP/DP modes and add support
 for X1E80100

Since this new platform supports both DP and eDP, it's the perfect time
to drop the dual compatible (eDP and DP) and figure out a different way
to specify the mode. After some off-list discussion, one suggested way
was to add a 'is-edp' property to the controller node and call
phy_set_mode to let the PHY know which mode it should configure itself.

The PHY counterpart patchset is here:

Changes in v2:
- Added Dmitry's R-b tag to both driver patches
- Dropped the if statement around assigning the is_edp in
  dp_display_probe, and fixed said assignment by using the connector
  type from match data instead.
- Moved the qcom,x1e80100-dp compatible where it belongs
- Re-worded the bindings commit message to follow Bjorn's suggestion
- Dropped the RFC tag as the approach doesn't seem to be questioned
  anymore 
- Link to v1: https://lore.kernel.org/r/20240221-x1e80100-display-refactor-connector-v1-0-86c0e1ebd5ec@linaro.org
