drm/bridge-connector: implement glue code for HDMI connector

2024-06-12T07:56:57+00:00

In order to let bridge chains implement HDMI connector infrastructure, add necessary glue code to the drm_bridge_connector. In case there is a bridge that sets DRM_BRIDGE_OP_HDMI, drm_bridge_connector will register itself as a HDMI connector and provide proxy drm_connector_hdmi_funcs implementation. Note, to simplify implementation, there can be only one bridge in a chain that sets DRM_BRIDGE_OP_HDMI. Setting more than one is considered an error. This limitation can be lifted later, if the need arises.

drm/bridge: correct DRM_BRIDGE_OP_EDID documentation

While the commit d807ad80d811 ("drm/bridge: add ->edid_read hook and drm_bridge_edid_read()") and the commit 27b8f91c08d9 ("drm/bridge: remove ->get_edid callback") replaced ->get_edid() callback with the ->edid_read(), they failed to update documentation.

drm/bridge: migrate bridge_chains to per-encoder file

2023-12-04T14:07:29+00:00

Instead of having a single file with all bridge chains, list bridges under a corresponding per-encoder debugfs directory. While we are at it, also slightly improve the formatting of the bridge data: split a single line entry into multiple lines, include the symbol name of the bridge funcs and add the textual representation of the bridge ops. Example of the listing: $ cat /sys/kernel/debug/dri/0/encoder-0/bridges bridge[0]: dsi_mgr_bridge_funcs type: [0] Unknown ops: [0] bridge[1]: lt9611uxc_bridge_funcs type: [11] HDMI-A OF: /soc@0/geniqup@9c0000/i2c@994000/hdmi-bridge@2b:lontium,lt9611uxc ops: [7] detect edid hpd Reviewed-by: Neil Armstrong Reviewed-by: Tomi Valkeinen Signed-off-by: Dmitry Baryshkov Link: https://patchwork.freedesktop.org/patch/msgid/20231203115315.1306124-3-dmitry.baryshkov@linaro.org

drm/bridge: Drop conditionals around of_node pointers

2023-09-06T15:32:37+00:00

This patch is based on commit c9e358dfc4a8 ("driver-core: remove conditionals around devicetree pointers"). Having conditional around the of_node pointer of the drm_bridge structure turns out to make driver code use ugly #ifdef blocks. Drop the conditionals to simplify drivers. While this slightly increases the size of struct drm_bridge on non-OF system, the number of bridges used today and foreseen tomorrow on those systems is very low, so this shouldn't be an issue. So drop #if conditionals by adding struct device_node forward declaration.
