Just like with the 1.4 series of patches This only introduces the
ability to authenticate and encrypt the link. These patches by
themselves don't constitute a complete and compliant HDCP content
protection solution but are a requirement for such a solution.
Summary of the changes
*Adds 2.2 code to the module
*Enabled HDCP 2.2 authentication/encryption
*Add type0/1 selection for 2.2
*Add MST support (Only tested single daisy chain usecase)
Bhawanpreet Lakha (11):
drm/amd/display: Add PSP block to verify HDCP2.2 steps
drm/amd/display: Add DDC handles for HDCP2.2
drm/amd/display: Add execution and transition states for HDCP2.2
drm/amd/display: Add logging for HDCP2.2
drm/amd/display: Change ERROR to WARN for HDCP module
drm/amd/display: Enable HDCP 2.2
drm/amd/display: Handle hdcp2.2 type0/1 in dm
drm/amd/display: Refactor HDCP to handle multiple displays per link
drm/amd/display: add force Type0/1 flag
drm/amd/display: Refactor HDCP encryption status update
drm/amd/display: fix events handling for hdcp

[Why]
All the HDCP transactions should be verified using PSP
[How]
This patch adds the psp calls we need to verify the steps

Cc: Bhawanpreet Lakha
[Why]
We need these to read and write to aux/i2c, during
authentication
[How]
Create read/write functions for all the steps
(Eg, h_prime, paring_info etc)

Cc: Bhawanpreet Lakha
[Why]
We need to log the state changes for 2.2
This patch extends the existing logging functions to handle
HDCP2.2.
[How]
We do this by adding if/else in the defines, and output the log
based on the hdcp version

[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.

[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).

[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

[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.

Cc: Bhawanpreet Lakha
[Why]
Before we had a disable_type1 flag, this forced HDCP 2.2 to type0
There was no way to force type1.
[How]
Remove disable_type1 flag and instead add a flag to force type0/1.

Cc: Bhawanpreet Lakha
[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.

[Why]
When we execute a event, pending events should be canceled. This leads
to cases where we execute the same event twice,if the new event is
scheduled to run before the old event.
Also watchdog event was being canceled inside callback event. This is
incorrect.
[How]
Cancel pending events before executing the current and fix watchdog
event being canceled by callback event
