[Intel-gfx] [RFC 1/3] drm/i915/hdmi: Optimize source audio parameter handling

Mitul Golani mitulkumar.ajitkumar.golani at intel.com
Thu Jun 15 07:07:21 UTC 2023


To enhance the relationship between the has_audio and the source
audio parameter, create a separate crtc_state audio property and
add the has_audio parameter into it. Additionally, update the
access of the has_audio parameter from the crtc_state pointer as
it is wrapped under the audio. These modifications establish
a more cohesive structure and improve the accessibility and
organization of the audio-related parameters within the codebase.

--v1:
- add audio instead of audio_config in crtc_state
- add only has_audio then update related parameter access
- refactor other member to different commit where it is being used
- update commit message and header
