Add support for notfier of panel blank/unblank events.
This allows external drivers such as touch, backlight
drivers etc to subscribe to panel related events.

Add support into the drm_mipi_dsi framework to support
unicasting DCS commands to specific DSI controls within a panel.
This is required for partial update where region of interest
spans only on one controller in a dual controller configuration.
Also, Some display panel have the requirement of waiting for certain
duration before dsi host can read back the response from panel during
a DCS read command. This change adds the support to store
the delay required in dsi message structure.

Create a new connector property to program colorspace to sink
devices. Modern sink devices support more than 1 type of
colorspace like 601, 709, BT2020 etc. This helps to switch
based on content type which is to be displayed. The decision
lies with compositors as to in which scenarios, a particular
colorspace will be picked.
This will be helpful mostly to switch to higher gamut colorspaces
like BT2020 when the media content is encoded as BT2020. Thereby
giving a good visual experience to users.
The expectation from userspace is that it should parse the EDID
and get supported colorspaces. Use this property and switch to the
one supported. Sink supported colorspaces should be retrieved by
userspace from EDID and driver will not explicitly expose them.
Basically the expectation from userspace is:
- Set up CRTC DEGAMMA/CTM/GAMMA to convert to some sink
colorspace
- Set this new property to let the sink know what it
converted the CRTC output to.
v2: Addressed Maarten and Ville's review comments. Enhanced
the colorspace enum to incorporate both HDMI and DP supported
colorspaces. Also, added a default option for colorspace.
v3: Removed Adobe references from enum definitions as per
Ville, Hans Verkuil and Jonas Karlman suggestions. Changed
Default to an unset state where driver will assign the colorspace
is not chosen by user, suggested by Ville and Maarten. Addressed
other misc review comments from Maarten. Split the changes to
have separate colorspace property for DP and HDMI.
v4: Addressed Chris and Ville's review comments, and created a
common colorspace property for DP and HDMI, filtered the list
based on the colorspaces supported by the respective protocol
standard.
v5: Made the property creation helper accept enum list based on
platform capabilties as suggested by Shashank. Consolidated HDMI
and DP property creation in the common helper.
v6: Addressed Shashank's review comments.
v7: Added defines instead of enum in uapi as per Brian Starkey's
suggestion in order to go with string matching at userspace. Updated
the commit message to add more details as well kernel docs.
v8: Addressed Maarten's review comments.
v9: Removed macro defines from uapi as per Brian Starkey and Daniel
Stone's comments and moved to drm include file. Moved back to older
design with exposing all HDMI colorspaces to userspace since infoframe
capability is there even on legacy platforms, as per Ville's review
comments.
v10: Fixed sparse warnings, updated the RB from Maarten and Jani's ack.
v11: Addressed Ville's review comments. Updated the Macro naming and
added DCI-P3 colorspace as well, defined in CTA 861.G spec.
v12: Appended BT709 and SMPTE 170M with YCC information as per Ville's
review comment to be clear and not to be confused with RGB.
v13: Reorder the colorspace macros.
v14: Removed DP as of now, will be added later once full support is
enabled, as per Ville's suggestion. Added Ville's RB.

This patch adds a blob property to get HDR metadata
information from userspace. This will be send as part
of AVI Infoframe to panel.
It also implements get() and set() functions for HDR output
metadata property.The blob data is received from userspace and
saved in connector state, the same is returned as blob in get
property call to userspace.
v2: Rebase and modified the metadata structure elements
as per Ville's POC changes.
v3: No Change
v4: Addressed Shashank's review comments
v5: Rebase.
v6: Addressed Brian Starkey's review comments, defined
new structure with header for dynamic metadata scalability.
Merge get/set property functions for metadata in this patch.
v7: Addressed Jonas Karlman review comments and defined separate
structure for infoframe to better align with CTA 861.G spec. Added
Shashank's RB.
v8: Addressed Ville's review comments. Moved sink metadata structure
out of uapi headers as suggested by Jonas Karlman.
v9: Rebase and addressed Jonas Karlman review comments.
v10: Addressed Ville's review comments, dropped the metdata_changed
state variable as its not needed anymore.

As of DP1.4, ENUM_PATH_RESOURCES returns a bit indicating
if FEC can be supported up to that point in the MST network.
The bit is the first byte of the ENUM_PATH_RESOURCES ack reply,
bottom-most bit (refer to section 2.11.9.4 of DP standard,
v1.4)
That value is needed for FEC and DSC support
Store it on drm_dp_mst_port

Add support for drivers to report the total number of MPDUs received
and the number of MPDUs received with an FCS error from a specific
peer. These counters will be incremented only when the TA of the
frame matches the MAC address of the peer irrespective of FCS
error.
It should be noted that the TA field in the frame might be corrupted
when there is an FCS error and TA matching logic would fail in such
cases. Hence, FCS error counter might not be fully accurate, but it can
provide help in detecting bad RX links in significant number of cases.
This FCS error counter without full accuracy can be used, e.g., to
trigger a kick-out of a connected client with a bad link in AP mode to
force such a client to roam to another AP.

Adds new member skip_resume to struct usb_bus to resolve ABI diff.
This patch also adds the capability to skip device resume during
system resume. It allows xHC to remain in low power mode and not
resume the bus when system wide resume happens.
Instead, the controller comes out of low power mode only
when usb device issues a remote wakeup or if there is
host initiated bus resume.
