Update minimum prefill lines for command mode
displays based on system recommendation for
different fps. Video mode display can support
prefill lines based on panel porches.

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.

CRTC client type is wrongly identified as RT_CLIENT
for WB as the API considers only RT and RT_RSC. Resolve
it by adding a new API to check for RT CTRC.

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
checks to allow programming the HW.

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.

that ESD is enabled on the particular panel. If not the
panel might end up in a bad state, if the trigger is
propagated successfully instead of reporting a failure.

Update the minimum encryption level only when there is a request
to do so coming from the DRM framework. This will ensure that any
previously set value will not be overwritten while processing
other commands. Failure to preserve the minimum encryption level
can result in secure content playback failure if the sink device
is not updated with the correct value.
