The TPD12S015, OPA362 and analog and HDMI connectors are now supported by DRM bridge drivers, and the omapdrm HDMI and VENC outputs can be handled through the drm_bridge API.

Use the drm_bridge_connector helper to create a connector for pipelines that use drm_bridge. This allows splitting connector operations across multiple bridges when necessary, instead of having the last bridge in the chain creating the connector and handling all connector operations internally.

In order to integrate with a chain of drm_bridge, the internal VENC encoder has to expose the mode valid, fixup and set, the enable and disable and the get modes operations through the drm_bridge API. Register a bridge at initialisation time to do so. Most of those operations are removed from the omap_dss_device as they are now called through the drm_bridge API by the DRM atomic helpers. The only exception is the .get_modes() operation that is still invoked through the omap_dss_device-based pipeline. For the time being make the next bridge in the chain optional as the VENC output is still based on omap_dss_device. The create_connector argument to the bridge attach function is also ignored for the same reason. This will be changed later when removing the related omapdrm-specific display drivers. Signed-off-by:

Move the omap_dss_device .set_timings(), .enable() and .disable() operations to the drm_bridge functions. As the drm_bridge for the HDMI encoder is unconditionally registered and attached, those operations will be called at the appropriate time. The omapdss device .set_infoframe() and .set_hdmi_mode() operations have no equivalent in drm_bridge. Thir content is thus moved to the bridge .enable() operation as the data they store is not needed before the HDMI encoder gets enabled. Signed-off-by:

In preparation of adding DRM bridge support to the hdmi5 encoder code, rework the EDID read to isolate data read. The hdmi_read_edid() function is the main entry point. It performs all initialisation steps required prior to reading the EDID (such as ensuring the device is powered on), as well as corresponding cleanup steps afterwards. EDID read itself is handled by hdmi_read_edid_data() that calls the hdmi5_core_ddc_read() function to read individual blocks. This new code architecture will allow reusing hdmi_read_edid() and hdmi5_core_ddc_read() for the drm_bridge EDID read implementation, while swapping out hdmi_read_edid_data() for the DRM drm_do_get_edid() function.

In order to support drm_bridge-based pipeline, the internal HDMI encoders will need to expose the EDID read operation through the drm_bridge API, and thus to expose a drm_bridge instance corresponding to the encoder. The HDMI encoders are however handled as omap_dss_device instances, which conflicts with this requirement. In order to move forward with the drm_bridge transition, add support for creating drm_bridge instances local to DSS outputs. If a local bridge is passed to the omapdss_device_init_output() function, it is used as the first bridge in the chain, and the omap_dss_device.next_bridge field is set to the next bridge for the use of the internal encoders' bridges.

The DSS core looks up the next device connected to an output by traversing the OF graph. It currently hardcodes the local port number to 0, which breaks any output with a different port number (SDI on OMAP3 and any DPI output but the first one). Fix this by repurposing the currently unused of_ports bitmask in omap_dss_device with an of_port output port number, and use it to traverse the OF graph. Signed-off-by:

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 needs to be moved to the display controller driver. To avoid code duplication in display controller drivers, add a new helper to create and manage a DRM connector backed by a chain of bridges. All connector operations are delegating to the appropriate bridge in the chain. Signed-off-by:
