Subject: [PATCH v5 0/5] Add support for DisplayPort on SA8775P platform

This series adds support for the DisplayPort controller
and eDP PHY v5 found on the Qualcomm SA8775P platform.

---
v2: Fixed review comments from Dmitry and Bjorn
	- Made aux_cfg array as const.
	- Reused edp_swing_hbr_rbr and edp_swing_hbr2_hbr3 for v5.

v3: Fixed review comments from Dmitry, Konrad and Bjorn
	- Used a for loop to write the dp_phy_aux_cfg registers.
	- Pre-defined the aux_cfg size to prevent any magic numbers.
	- Added all the necessary DPTX controllers for this platform.

v4: Fixed review comments from Dmitry and Krzysztof
	- Removed the "reviewed by" and kept only the "acked by" for 
	  patch 1.
	- Updated the commit message of patch 5 to mention specifically
	  about the validation of "only" MDSS0 DPTX0 and DPTX1.

v5: Fixed review comment from Dmitry in patch 5
	- Aligned the register starting address for display port as part 
	  of device description with respect to other targets.

Below patches are applied:
