This is a resend, since the previous submission got no responses. The patches have been reviewed/acked by several maintainers. Can we please gain some attention and either get it merged or understand what should be changed / improved. This series is required to delivere HPD events from altmode driver to the MSM DP driver in the sane way.
Note, numbering for this series starts from v5, since there were several revisions for this patchset under a different series title ([1]). USB altmodes code would send OOB notifications to the drm_connector specified in the device tree. However as the MSM DP driver uses drm_bridge_connector, there is no way to receive these event directly. Implement a bridge between oob_hotplug_event and drm_bridge's hpd_notify. Merge strategy: since this series touches i915 code, it might make sense to merge all three patches through drm-intel. [1] https://patchwork.freedesktop.org/series/103449/ Changes since v6: - Rebased on top of linux-next. Fixed the freshly added new drm_connector_oob_hotplug_event() call. Changes since v5: - Fixed checkpatch warning in the first patch (noted by intel-gfx CI). Changes since v4: - Picked up the patchset - Dropped msm-specific patches - Changed drm_bridge_connector_oob_hotplug_event to call connector's HPD callback directly, rather than going through the last bridge's hpd_notify - Added proper fwnode for the drm_bridge_connector Bjorn Andersson (1): drm: Add HPD state to drm_connector_oob_hotplug_event() Dmitry Baryshkov (2): drm/bridge_connector: stop filtering events in drm_bridge_connector_hpd_cb() drm/bridge_connector: implement oob_hotplug_event drivers/gpu/drm/drm_bridge_connector.c | 36 ++++++++++++++----- drivers/gpu/drm/drm_connector.c | 6 ++-- .../gpu/drm/i915/display/intel_display_core.h | 3 ++ drivers/gpu/drm/i915/display/intel_dp.c | 17 +++++++-- drivers/usb/typec/altmodes/displayport.c | 17 ++++----- include/drm/drm_connector.h | 6 ++-- 6 files changed, 62 insertions(+), 23 deletions(-) -- 2.39.2
