There is lag or lead in the FPS during dynamic clock change,
along with the increment or decrement in clock. So, HFP or
VFP are adjusted to ensure a constant FPS.

DSI host vsync is expected to align with panel internal vsync
during transition from command mode to video mode operation.
In order to facilitate this, keep panel TE enabled in video mode
operation until it is aligned with vysnc.

Add support for PPS command for VDC-m. This shall be sent from the
encoder to the decoder such that both can produce the same model
state.

Parse the DTS panel type settings. Consider the default
panel physical type as LCD. We need to set OLED in DTS if
the panel is an OLED type.

DSI driver sends nolp commands when DSI connector power
modes is set SDE_MODE_DPMS_ON or SDE_MODE_DPMS_OFF. This
is invalid panel configuration. It should only send nolp
commmand to panel when it is in LP1/LP2 mode.

Video and command mode will be included in same timing node
when POMS is enabled, but DFPS is only applicable for video
mode, so add this change to differentiate panel mode, and fill
display mode according to panel mode.

Change updates frame transfer time calculations. Frame threshold
is provided as input to decide on the final transfer time.
Panel dsi clock node followed by mdp transfer time node
will take priority in selecting final transfer time than frame
threshold time.

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.

Change updates dsi clock calculations for command mode
as per recommendation. Now dsi clocks are tied to
frame transer time. Propagate correct frame transfer
time to hal to update mdp clocks and bandwidth needed
accordingly.

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.
