From 0d024974014f39207c5f52e770059b5bac35ea6d Mon Sep 17 00:00:00 2001 From: Paloma Arellano Date: Thu, 15 Feb 2024 11:15:56 -0800 Subject: drm/dp: add an API to indicate if sink supports VSC SDP YUV420 format is supported only in the VSC SDP packet and not through MSA. Hence add an API which indicates the sink support which can be used by the rest of the DP programming. changes in v5: - rebased on top of drm-tip changes in v4: - bail out early if dpcd rev check fails changes in v3: - fix the commit title prefix to drm/dp - get rid of redundant !! - break out this change from series [1] to get acks from drm core maintainers Changes in v2: - Move VSC SDP support check API from dp_panel.c to drm_dp_helper.c [1]: https://patchwork.freedesktop.org/series/129180/ Reviewed-by: Dmitry Baryshkov Signed-off-by: Paloma Arellano Signed-off-by: Abhinav Kumar Signed-off-by: Dmitry Baryshkov Link: https://patchwork.freedesktop.org/patch/msgid/20240215191556.3227259-1-quic_abhinavk@quicinc.com --- include/drm/display/drm_dp_helper.h | 2 ++ 1 file changed, 2 insertions(+) (limited to 'include/drm') diff --git a/include/drm/display/drm_dp_helper.h b/include/drm/display/drm_dp_helper.h index 1f41994796d3..0c1a4021e098 100644 --- a/include/drm/display/drm_dp_helper.h +++ b/include/drm/display/drm_dp_helper.h @@ -100,6 +100,8 @@ struct drm_dp_vsc_sdp { void drm_dp_vsc_sdp_log(struct drm_printer *p, const struct drm_dp_vsc_sdp *vsc); +bool drm_dp_vsc_sdp_supported(struct drm_dp_aux *aux, const u8 dpcd[DP_RECEIVER_CAP_SIZE]); + int drm_dp_psr_setup_time(const u8 psr_cap[EDP_PSR_RECEIVER_CAP_SIZE]); static inline int -- cgit v1.2.3
