These patches add Display-Port driver on SnapDragon/msm hardware. This series also contains device-tree bindings for msm DP driver. It also contains Makefile and Kconfig changes to compile msm DP driver.
The block diagram of DP driver is shown below:

Changes in v7:
- Modify cover letter description and fix title. - Introduce dp-controller.yaml for common bindings across SOC - Rename dp-sc7180.yaml to dp-controller-sc7180.yaml for SC7180 bindings - Rename compatible string to qcom,sc7180-dp - Add assigned-clocks and assigned-clock-parents properties in bindings - Remove redundant code from driver - Extend series to include HPD detection logic
Changes in v8:
- Add MDSS AHB clock in bindings - Replace mode->vrefresh use with drm_mode_vrefresh API - Remove redundant aux config code from parser and aux module - Assign default max lanes if data-lanes property is not available - Fix use-after-free during DP driver remove - Unregister hardware clocks during driver cleanup
