d92000cdd4 disp: msm: add resource caps structure and api changes
Create a data structure to maintain available hardware resources
and track capabilities. This data structure is used to send
the current available resources and caps information to
connector ops get_mode_info, get_modes and validate_mode to
process the display mode.

39bc44163c disp: msm: dsi: unify dynamic clk support for command mode
Currently the dynamic bit clock switch trigger for command mode
is supported via sysfs node. This might lead to unnecessary
race conditions, when dsi driver is enabling the dsi bit clock
as part of commit and at the same time if bit rate change via
sysfs happens. So make the trigger happens via kernel mode set
call as done for video mode.

b0f2e2222e disp: msm: dsi: add support for dsi dynamic clock switch
This change adds support for dynamic switching of dsi clocks
to avoid RF interference issues. Also with dynamic dsi clock
switch feature coming into picture, now populate the supported
refresh rate as list instead of providing a range. Modify the
logic to enumerate all the modes in dsi driver, taking dynamic
bit clocks, resolutions and refresh rates into account.

0cfa54e503 disp: msm: dsi: avoid panel mode switch flag after deep sleep
This change updates the checks needed before setting the flag
to enable panel switching between command and video mode.
New crtc active state remains disabled and it causes a failure
in the previous case.

21edecd3b1 disp: msm: Add support for seamless panel operating mode switch
DSI display may support video mode and command mode both and it may
support transition between these two modes.
This change adds seamless transition between these two modes for DSI
display by avoiding crtc enable/disable and panel power on/off
during modeset.
