Subject: [PATCH v10 0/5] Add support for DisplayPort driver on SnapDragon
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
Changes in v9:
- Drop YAML bindings change from the series
- Use assigne-clock-parents property and remove clk_set_parent use from code
- Access register address space without name
- Fix DP register dump utility
- Disable DP clocks after vsync generated
- Avoid 64-bit modulo operation
- Drop any unused code and fix function proptotyes to avoid W=1 warnings
- Drop DRM_MSM_DP_10NM_PLL config as only 10nm PLL is available
Changes in v10:
- Fix help description of Kconfig entry
