64827cadcc drm/amd/display: block passive dongle EDID Emulation for USB-C ports
[Why]
Emulating passive dongle on USB-C port causes issue on some asics.

[How]
Check for DP_IS_USB_C flag in bios parser and propagate it to
encoder features flags. If DP_IS_USB_C flag is set and it is trying to
emulate passive dongle, then return fail.

ac627caf6b drm/amd/display: add gpio lock/unlock
[Why]
When querying HPD via GPIO flow,
it will create a new gpio object then free in the end of query.
There is a irql issue for HPD querying at ISR level.

[How]
Therefore, creating the HPD gpio object in dc_link and set it as unlcok in default.
1. reducing unnecessary malloc/free when HPD querying.
2. reducing init GPIO flow.
3. add lock/unlock to prevent multi gpio service running.

46659a83e4 drm/amd/display: Support reading hw state from debugfs file
[Why]

Logging hardware state can be done by triggering a write to the
debugfs file. It would also be useful to be able to read the hardware
state from the debugfs file to be able to generate a clean log without
timestamps.

[How]

Usage: cat /sys/kernel/debug/dri/0/amdgpu_dm_dtn_log

Threading is an obvious concern when dealing with multiple debugfs
operations and blocking on global state in dm or dc seems unfavorable.

Adding an extra parameter for the debugfs log context state is the
implementation done here. Existing code that made use of DTN_INFO
and its associated macros needed to be refactored to support this.

We don't know the size of the log in advance so it reallocates the
log string dynamically. Once the log has been generated it's copied
into the user supplied buffer for the debugfs. This allows for seeking
support but it's worth nothing that unlike triggering output via
dmesg the hardware state might change in-between reads if your buffer
size is too small.

While there is support for using and quering DFS bypass clocks the

notified to enter DFS bypass mode and the correct display engine clock
frequency can be acquired.
