Currently the DP display's states are not able to handle
the use cases like suspend/resume. The required steps of
host initialization and ready are not properly followed
in such cases. Define proper DP display states, set and
unset at the right places to make sure dp is in proper
state in such cases.

When plane is detached from crtc in one atomic commit and then
attached to another crtc in the next atomic commit, the second
plane state swap will happen when the first commit is still running
in the previous crtc's worker thread, which will result in two
threads programming the same plane and run into undeterministic
state.
Fix is to add plane_mask check before state swap, together with
crtc_mask check. This will make sure there is no pending worker
thread working on the same plane.

As per new requirements from DP 1.4a CTS, DUT (device under test)
should update the TE (test equipment) with the correct checksum
of the EDID even though the EDID is corrupted. Update the TE
with the checksum stored in the connector to meet this new
requirement.

This ensures that there are no spurious notifications that are

changes. This is used as a signal for power-mode
completion by user-mode. Allow preparing/signalling

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

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.

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.

video mode.
