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
This series depends-on:
https://patchwork.freedesktop.org/patch/366159/
If a single patch is a dependency, please coordinate your work and send
as 1 series.
To put it another way, I'm just going to ignore this series until the
dependency is sorted out.
Sure I will wait till previous patch is resolved.
https://patchwork.freedesktop.org/patch/369859/
Probably the same goes for this too, but I care less as it's not the
binding...
Above patch is not compile time dependency, but without it we see issues
during runtime.
So will be removed from dependency list.
Thanks.
