7a7ebfa85f thunderbolt: Power cycle the router if NVM authentication fails
On zang's Dell XPS 13 9370 after Thunderbolt NVM firmware upgrade the
Thunderbolt controller did not come back as expected. Only after the
system was rebooted it became available again. It is not entirely clear
what happened but I suspect the new NVM firmware image authentication
failed for some reason. Regardless of this the router needs to be power
cycled if NVM authentication fails in order to get it fully functional
again.

This modifies the driver to issue a power cycle in case the NVM
authentication fails immediately when dma_port_flash_update_auth()
returns. We also need to call tb_switch_set_uuid() earlier to be able to
fetch possible NVM authentication failure when DMA port is added.

45375a501f drm/amd/display: Refactor HDCP encryption status update
[Why]
The old way was to poll PSP and update the properties. But due to a
limitation in the PSP interface this doesn't work for MST.

[How]
According to PSP if set_encryption return success, the link is encrypted
and the only way it will not be is if we get a link loss(which we handle
already).

So this method should be good enough to report HDCP status.

b1abe5586f drm/amd/display: Refactor HDCP to handle multiple displays per link
[Why]
We need to do this to support HDCP over MST

Currently we save a display per link, in a MST case we need to save
multiple displays per link.

[How]
We can create an array per link to cache the displays, but it
complicates the design. Instead we can use the module to cache the
displays.

Now we will always add all the displays to the module, but we use the
adjustment flag to disable hdcp on all of them before they are added.

When we want to enable hdcp we just query the display(cache), remove
it then add it back with different adjustments. Its the similar for
disable.

53e108aa99 drm/amd/display: Handle hdcp2.2 type0/1 in dm
[Why]
HDCP 2.2 uses type0 and type1 content type. This is passed to the receiver
to stream the proper content.

For example, in a MST case if the main
device is HDCP2.2 capable but the secondary device is only 1.4 capabale
we can use Type0

Type0 content: use HDCP 1.4 or HDCP2.2 type0
Type1 content: Only use HDCP 2.2 type1

[How]
We use the "hdcp content type" property in drm. We use the
disable_type1 flag in hdcp module to select the type based on the
properties.

For updating the property we use the same logic as 1.4, but now we
consider content_type as well and update the property if the
requirements are met

da283469e0 drm/amd/display: Enable HDCP 2.2
[Why]
HDCP 2.2 was disabled, we need to enable it

[How]
-Update display topology to support 2.2
-Unset hdcp2.disable in update_config
-Change logic of event_update_property, now we set the property to be
ENABLED for any level of encryption (2.2 or 1.4).

2e956df291 drm/amd/display: Change ERROR to WARN for HDCP module
[Why]
HDCP is a bit finicky so we try it 3 times, this leads to a case where
if we fail the first time and pass the second time the error is still
shown in dmesg for the first failed attempt.

This leads to false positive errors.

[How]
Change the logging from ERROR to WARNING. Warnings are still shown in dmesg
to know what went wrong.

f6fe4053b9 drm/amd/display: Use a temporary copy of the current state when updating DSC config
[why]
When updating DSC config, a new config has to be validated before proceeding
with applying the update. Validation, however, modifies the current state.
This means DSC config validation would affect pipe re-assignment, causing
intermittent screen corruption issues when ODM is required for DSC.

[how]
- Use a copy of the current state for modified DSC config validation
- Set the update type to FULL_UPDATE to correctly validate and set the
  actual state used for committing the streams

a6e4da40bd drm/amd/display: Spin for DMCUB PHY init in DC
[Why]
DCN will hang if we access registers before PHY init is done.

So we need to spin or abort.

[How]
On hardware with DMCUB running and working we shouldn't time out
waiting for this to finish and we shouldn't hit the spin cycle.

If there's no hardware support then we should exit out of the function
early assuming that PHY init was already done elsewhere.

If we hit the timeout then there's likely a bug in firmware or software
and we need to debug - add errors and asserts as appropriate.

46250a0cba drm/amd/display: Avoid conflict between HDR multiplier and 3dlut
[WHY]
There can be a conflict between OS HDR multiplier and 3dlut HDR
multiplier, which are both sent to DC.

[HOW]
Instead of having dc determine which HDR multiplier to use, make the
decision in dm and send only the intended value in a surface update.
Store the current OS HDR multiplier and determine whether to use it or
the 3dlut's multiplier before sending the surface update to dc. Send
multiplier to dc in fixed31_32 format, dc then converts it to hw format.
