to be logged every frame.

Send the hotplug notification to the user space only when there
is a state change e.g. from connect to disconnect, or vice versa.
This ensures that there are no spurious notifications that are
sent to the user space.

With the new ASYNC power-mode changes, user-mode can
request for retire/release fences during power-mode
changes. This is used as a signal for power-mode
completion by user-mode. Allow preparing/signalling
these fences during crtc enable/disable to support it.

Limit clock rate of shadow VCO clock as normal VCO clock.
For larger bit clock rate gap between switched ones, the clock switching
would fail due to mismatched VCO clock rate between normal VCO clock and
shadow one.

Add support to pass extended capability information to the DPCD
debugfs node. This will help to validate features like VSC support
using debugfs node.
Usage will be the same as before and the change will automatically
detect the presence of extended capability field and expect
additional bytes of information.

Add the colorspace property for DP controller for MSM. Also, change
the default method to send the colorimetry information to the sink
from MISC bits of MSA to VSC SDP packets if the sink supports it. This
helps to avoid dynamic switches between the packet types for sending
the colorimetry information during BT2020 and DCI-P3 use-cases.

Currently a lot of information is packed into the HDR data structure of
the catalog panel making it difficult to individually control the
parameters like colorimetry and other information sent using
VSC SDP packets.
Break up the structure into individual VSC SDP colorimetry, HDR
infoframe and DHDR VSIF packets.
This makes it easier to control each of these parameters independently.
For example, when only the colorspace is changed its sufficient to
update only the VSC SDP colorimetry packets.
Also align these packets with the upstream DP helper header defines.

Populate the supported colorspaces property for DP
as part of getting the display modes.
This will expose the supported colorspaces of the sink to
userspace and in-turn the userspace shall pick the colorspace
suitable for the use-case.

The UIDLE s/w maintains few state variables based
on which ctl & debug counter hw setup is skipped
few times. Skipping this during idle-pc restore
leads to UIDLE not setup correctly. Fix the state

Input handler is used for early wakeup DSI and MDP clocks from
idle power collapse. DSI clock won't be disabled in video mode
during idle power collapse, so the input hanlder isn't needed
for video mode.
This change avoids the input handler to be registered in
video mode.
