Display clocks and IRQs are disabled during idle state
on command mode for power saving, and will be enabled
when a new frame commits to display driver. But enable
display clocks and IRQs will cause some latency.
So add a new SDE custom IOCTL for user-space to early wake
up display before first frame commits to kernel.

Currently DP driver determines if a mode is DSC capable
based on a DTSI entry and the required number of DSC
to support it. This approach does not scale when there
is an overlap in DSC requirement between DSI displays
and external DP display, thus causing one of the display to
report modes that cannot be supported.
This change compares the resources reserved for DP driver
calculated at initialization time and the currently available
ones to determine the correct number of resources that DP driver
can use. It also adds DSC and topology filtering logic and moves
DSC hardware specific from DP driver to SDE driver.

Make msm_drm into single module and all child driver
registers and unregisters are handled from parent's
register and unregister respectively.

The DRM framework only calls the driver's preclose callback
function if the LEGACY driver feature is enabled. Therefore
strip out this logic as it never gets executed since LEGACY
is not supported for msm_drm driver.

Since some APIs previously used during lastclose are no longer
exposed to drivers (__drm_atomic_helper_disable_plane, and
__drm_atomic_helper_set_config), make kms a DRM client and use
the drm_client_modeset_commit_force API to do lastclose cleanup.

Update the topology allocation by considering the required
mode clock (vtotal x htotal x fps * fudge factor). Modes with
a clock that exceeds the maximum SDE clock will be denoted as
requiring a topology that uses two layer mixers.

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.

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.
