2020-02-26drm/bridge: simple-bridge: Add support for non-VGA bridgesLaurent Pinchart
Create a new simple_bridge_info structure that stores information about the bridge model, and store the bridge timings in there, along with the connector type. Use that new structure for of_device_id data. This enables support for non-VGA bridges.

2020-02-26drm/bridge: dumb-vga-dac: Rename internal symbols to simple-bridgeLaurent Pinchart
The dumb-vga-dac driver is a simple DRM bridge driver for simple VGA DACs that don't require configuration. Other non-VGA bridges fall in a similar category, and would benefit from a common driver. Prepare for this by renaming the internal symbols from dumb-vga-dac to simple-bridge.

2020-02-26drm/bridge: Extend bridge API to disable connector creationLaurent Pinchart
Most bridge drivers create a DRM connector to model the connector at the output of the bridge. This model is historical and has worked pretty well so far, but causes several issues: - It prevents supporting more complex display pipelines where DRM connector operations are split over multiple components. For instance a pipeline with a bridge connected to the DDC signals to read EDID data, and another one connected to the HPD signal to detect connection and disconnection, will not be possible to support through this model. - It requires every bridge driver to implement similar connector handling code, resulting in code duplication. - It assumes that a bridge will either be wired to a connector or to another bridge, but doesn't support bridges that can be used in both positions very well (although there is some ad-hoc support for this in the analogix_dp bridge driver). In order to solve these issues, ownership of the connector should be moved to the display controller driver (where it can be implemented using helpers provided by the core). Extend the bridge API to allow disabling connector creation in bridge drivers as a first step towards the new model. The new flags argument to the bridge .attach() operation allows instructing the bridge driver to skip creating a connector. Unconditionally set the new flags argument to 0 for now to keep the existing behaviour, and modify all existing bridge drivers to return an error when connector creation is not requested as they don't support this feature yet. The change is based on the following semantic patch, with manual review and edits. @ rule1 @ identifier funcs; identifier fn; @@ struct drm_bridge_funcs funcs = { ..., .attach = fn }; @ depends on rule1 @ identifier rule1.fn; identifier bridge; statement S, S1; @@ int fn( struct drm_bridge *bridge + , enum drm_bridge_attach_flags flags ) { ... when != S + if (flags & DRM_BRIDGE_ATTACH_NO_CONNECTOR) { + DRM_ERROR("Fix bridge driver to make connector optional!"); + return -EINVAL; + } + S1 ... } @ depends on rule1 @ identifier rule1.fn; identifier bridge, flags; expression E1, E2, E3; @@ int fn( struct drm_bridge *bridge, enum drm_bridge_attach_flags flags ) { <... drm_bridge_attach(E1, E2, E3 + , flags ) ...> } @@ expression E1, E2, E3; @@ drm_bridge_attach(E1, E2, E3 + , 0 ) Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Reviewed-by: Boris Brezillon <boris.brezillon@collabora.com> Acked-by: Sam Ravnborg <sam@ravnborg.org> Reviewed-by: Tomi Valkeinen <tomi.valkeinen@ti.com> Tested-by: Sebastian Reichel <sebastian.reichel@collabora.com> Reviewed-by: Sebastian Reichel <sebastian.reichel@collabora.com> Acked-by: Daniel Vetter <daniel.vetter@ffwll.ch> Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com> Link: https://patchwork.freedesktop.org/patch/msgid/20200226112514.12455-10-laurent.pinchart@ideasonboard.com
2020-02-26drm/bridge: Add connector-related bridge operations and dataLaurent Pinchart
To support implementation of DRM connectors on top of DRM bridges instead of by bridges, the drm_bridge needs to expose new operations and data: - Output detection, hot-plug notification, mode retrieval and EDID retrieval operations - Bitmask of supported operations - Bridge output type - I2C adapter for DDC access Add and document these. Three new bridge helper functions are also added to handle hot plug notification in a way that is as transparent as possible for the bridges.
