[PATCH v2 0/4] Enlarge tracepoints in the display component

[Rodrigo Siqueira]

Debug issues related to display can be a challenge due to the complexity
around this topic and different source of information might help in this
process. We already have support for tracepoints inside the display
component, i.e., we have the basic functionalities available and we just
need to expand it in order to make it more valuable for debugging. For
this reason, this patchset reworks part of the current tracepoint
options and add different sets of tracing inside amdgpu_dm, display
core, and DCN10. The first patch of this series just rework part of the
current tracepoints and the last set of patches introduces new
tracepoints.

This first patchset version is functional. Please, let me know what I
can improve in the current version but also let me know what kind of
tracepoint I can add for the next version. 

Finally, I want to highlight that this work is based on a set of patches
originally made by Nicholas Kazlauskas.

Change in V2:
- I added another patch for capturing the clock state for different display
  architecture.

Rodrigo Siqueira (4):
  drm/amd/display: Rework registers tracepoint
  drm/amd/display: Add tracepoint for amdgpu_dm
  drm/amd/display: Add pipe_state tracepoint
  drm/amd/display: Add tracepoint for capturing clocks state
