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 Signed-off-by: Mitul Golani --- drivers/gpu/drm/i915/display/g4x_dp.c | 4 ++-- drivers/gpu/drm/i915/display/g4x_hdmi.c | 16 ++++++++-------- drivers/gpu/drm/i915/display/intel_audio.c | 6 +++--- drivers/gpu/drm/i915/display/intel_cdclk.c | 6 +++--- .../gpu/drm/i915/display/intel_crtc_state_dump.c | 4 ++-- drivers/gpu/drm/i915/display/intel_ddi.c | 2 +- drivers/gpu/drm/i915/display/intel_display.c | 4 ++-- .../gpu/drm/i915/display/intel_display_types.h | 6 +++--- drivers/gpu/drm/i915/display/intel_dp.c | 2 +- drivers/gpu/drm/i915/display/intel_dp_mst.c | 2 +- drivers/gpu/drm/i915/display/intel_hdmi.c | 2 +- drivers/gpu/drm/i915/display/intel_sdvo.c | 10 +++++----- 12 files changed, 32 insertions(+), 32 deletions(-) diff --git a/drivers/gpu/drm/i915/display/g4x_dp.c b/drivers/gpu/drm/i915/display/g4x_dp.c index c58a3f249a01..af76a71e757c 100644 --- a/drivers/gpu/drm/i915/display/g4x_dp.c +++ b/drivers/gpu/drm/i915/display/g4x_dp.c @@ -345,7 +345,7 @@ static void intel_dp_get_config(struct intel_encoder *encoder, tmp = intel_de_read(dev_priv, intel_dp->output_reg);

This allows for the calculation of HDMI audio source capabilities with respect to the available mode bandwidth. These capabilities encompass parameters such as supported frequency and channel configurations. --v1: - Refactor max_channel and max_rate to this commit as it is being initialised here - Remove call for intel_audio_compute_eld to avoid any regression while merge. instead call it in different commit when it is defined. - Use int instead of unsigned int for max_channel and max_frequecy - Update commit message and header --v2: - Use signed instead of unsigned variables. - Avoid using magic numbers and give them proper name.
