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:

From: Jeykumar Sankaran
Add display port support in DPU by creating hooks
for DP encoder enumeration and encoder mode
initialization.
changes in v2:
- rebase on [2] (Sean Paul)
- remove unwanted error checks and
switch cases (Jordan Crouse)
[1]
From: Chandan Uddaraju
Add the needed DP PLL specific files to support
display port interface on msm targets.
The DP driver calls the DP PLL driver registration.
The DP driver sets the link and pixel clock sources.
Changes in v2:
-- Update copyright markings on all relevant files.
-- Use
Configure HPD registers in DP controller and
enable HPD interrupt.
Add interrupt to handle HPD connect and disconnect events.
Changes in v8: None

The drm/omap driver was fixed to correct an issue where using a
divider of 32 breaks the DSS despite the TRM stating 32 is a valid
number. Through experimentation, it appears that 31 works, and
it is consistent with the value used by the drm/omap driver.
This patch fixes the divider for fbdev

Drop use of the legacy drm_bus_flags member and use the more descriptive
_SAMPLE_ variant.
No functional change.

Use inline comments for the drm_bus_flags enum.
This makes it easier to add more description comments in the future
should the need arise.

Replace all uses of the legacy drm_bus_flags with their relevant
_SAMPLE_ variant.
This is a 1:1 replacement, no effort was made to validate the actual
bus flags for the panels.
Note:
DRM_BUS_FLAG_PIXDATA_SAMPLE_POSEDGE = DRM_BUS_FLAG_PIXDATA_NEGEDGE
DRM_BUS_FLAG_PIXDATA_SAMPLE_NEGEDGE =
Use the more descriptive _DRIVE_ variants thus avoiding the
legacy drm_bus_flags values.

Drop all uses of legacy drm_bus_flags, and then drop the flags.
Follow-up with a patch to inline the documentation of the flags.
The conversion was triggered by Laurent's clean-up of
the bus_flags use in panel-simple.
