drm/bridge: connector: add support for HDMI codec frameworkAdd necessary glue code to be able to use new HDMI codec framework fromthe DRM bridge drivers. The drm_bridge implements a limited set of thehdmi_codec_ops interface, with the functions accepting bothdrm_connector and drm_bridge instead of just a generic void pointer.This framework is integrated with the DRM HDMI Connector framework, butcan also be used for DisplayPort connectors.Reviewed-by: Maxime Ripard Tested-by: Dave Stevenson Link: https://patchwork.freedesktop.org/patch/msgid/20241224-drm-bridge-hdmi-connector-v10-4-dc89577cd438@linaro.orgSigned-off-by: Dmitry Baryshkov List of files: /linux-6.15/include/drm/drm_bridge.h

Fri, 07 Jun 2024 13:23:00 +0000

drm/bridge-connector: implement glue code for HDMI connectorIn order to let bridge chains implement HDMI connector infrastructure,add necessary glue code to the drm_bridge_connector. In case there is abridge that sets DRM_BRIDGE_OP_HDMI, drm_bridge_connector will registeritself as a HDMI connector and provide proxy drm_connector_hdmi_funcsimplementation.Note, to simplify implementation, there can be only one bridge in achain that sets DRM_BRIDGE_OP_HDMI. Setting more than one is consideredan error. This limitation can be lifted later, if the need arises.Acked-by: Maxime Ripard Link: https://patchwork.freedesktop.org/patch/msgid/20240607-bridge-hdmi-connector-v5-3-ab384e6021af@linaro.orgSigned-off-by: Dmitry Baryshkov List of files: /linux-6.15/include/drm/drm_bridge.h

d8dfccde - drm/bridge: Drop conditionals around of_node pointers

Thu, 31 Aug 2023 08:09:36 +0000

drm/bridge: Drop conditionals around of_node pointersThis patch is based on commit c9e358dfc4a8 ("driver-core: removeconditionals around devicetree pointers").Having conditional around the of_node pointer of the drm_bridgestructure turns out to make driver code use ugly #ifdef blocks. Drop theconditionals to simplify drivers. While this slightly increases the sizeof struct drm_bridge on non-OF system, the number of bridges used todayand foreseen tomorrow on those systems is very low, so this shouldn't bean issue.So drop #if conditionals by adding struct device_node forward declaration.Suggested-by: Douglas Anderson Signed-off-by: Biju Das Reviewed-by: Douglas Anderson Reviewed-by: Laurent Pinchart Signed-off-by: Douglas Anderson Link: https://patchwork.freedesktop.org/patch/msgid/20230831080938.47454-3-biju.das.jz@bp.renesas.com List of files: /linux-6.15/include/drm/drm_bridge.h

Wed, 02 Aug 2023 07:04:11 +0000

drm/bridge: Add debugfs print for bridge chainsDRM bridges are not visible to the userspace and it may not beimmediately clear if the chain is somehow constructed incorrectly. Ihave had two separate instances of a bridge driver failing to do adrm_bridge_attach() call, resulting in the bridge connector not beingpart of the chain. In some situations this doesn't seem to cause issues,but it will if DRM_BRIDGE_ATTACH_NO_CONNECTOR flag is used.Add a debugfs file to print the bridge chains. For me, on this TI AM62based platform, I get the following output:encoder[39] bridge[0] type: 0, ops: 0x0 bridge[1] type: 0, ops: 0x0, OF: /bus@f0000/i2c@20000000/dsi@e:toshiba,tc358778 bridge[2] type: 0, ops: 0x3, OF: /bus@f0000/i2c@20010000/hdmi@48:lontium,lt8912b bridge[3] type: 11, ops: 0x7, OF: /hdmi-connector:hdmi-connectorTested-by: Alexander Stein Reviewed-by: Laurent Pinchart Signed-off-by: Tomi Valkeinen Acked-by: Neil Armstrong Signed-off-by: Neil Armstrong Link: https://patchwork.freedesktop.org/patch/msgid/20230802-drm-bridge-chain-debugfs-v4-1-7e3ae3d137c0@ideasonboard.com List of files: /linux-6.15/include/drm/drm_bridge.h
