Hello,
This series is the second version of a previously unnamed series that contained
[PATCH 1/2] drm/panel: Add and fill drm_panel type field [PATCH 2/2] drm/bridge: panel: Use drm_panel.type instead of explicit connector_type
The purpose of the change is to allow panels to report their type, in order to create drm_connector instances with appropriate types in the upper layers.
Patch 1/4 fixes two panel drivers to add missing drm_panel_init() calls. Patch 2/4 then refactors the panel drivers to initialise the dev and funcs field through the drm_panel_init() function instead of doing so manually.
In patch 3/4 the drm_panel structure receives a new connector_type field to report its type, set through drm_panel_init(), and all connector drivers are updated accordingly. The panel-simple driver however only reports the LVDS connector type for known-to-be-LVDS panels, while all other leave the field initialised to 0, corresponding to DRM_MODE_CONNECTOR_Unknown. Panels supported by that driver will need to be reviewed one by one and their type updated. This was done to avoid reporting an incorrect type, allowing upper layers to catch DRM_MODE_CONNECTOR_Unknown and WARN() to trigger an update of the corresponding panel.
Patch 4/4 finally modifies drm_panel_bridge_add() and its devm_ counterpart to replace the connector type argument with the type reported by the panel. This can't unfortunately be forced upon all drivers as several of them hardcode a DRM_MODE_CONNECTOR_Unknown type, and would then change the connector type reported to userspace, leading to possible breakages. A new function, drm_panel_bridge_add_typed(), is added with the existing behaviour of drm_panel_bridge_add() to create a panel bridge with a forced connector type, and drivers are switched to using that function. They should then be switched back one by one to drm_panel_bridge_add() after careful review (and clever handling of the connector type change issue). The drm_panel_bridge_add_typed() function is marked as deprecated and should not be used in new code.
