drm: rcar-du: Convert LVDS encoder code to bridge driver

2018-03-07T16:06:49Z

The LVDS encoders used to be described in DT as part of the DU. They now have their own DT node, linked to the DU using the OF graph bindings. This allows moving internal LVDS encoder support to a separate driver modelled as a DRM bridge. Backward compatibility is retained as legacy DT is patched live to move to the new bindings.

drm: Convert to using %pOF instead of full_name

2017-07-26T11:45:06Z

Now that we have a custom printf format specifier, convert users of full_name to use %pOF instead. This is preparation to remove storing of the full path string for each node.

drm: rcar-du: Hardcode encoders types to DRM_MODE_ENCODER_NONE

2017-04-04T14:04:04Z

Unlike the connector type, the encoder type is unused by userspace. As it is equally unused in the driver, except in a single location where the connector type can be used instead, hardcode it to DRM_MODE_ENCODER_NONE. This allow removing all code that tries to determine (unsuccessfully in case a bridge is used) the encoder type. Signed-off-by: Laurent Pinchart

drm: rcar-du: Replace manual bridge implementation with DRM bridge

2017-04-04T14:04:02Z

The rcar-du driver contains a manual implementation of HDMI and VGA bridges. Use DRM bridges to replace it. Signed-off-by: Laurent Pinchart

drm: rcar-du: Add support for LVDS mode selection

2017-04-04T14:03:57Z

Retrieve the LVDS mode from the panel and configure the LVDS encoder accordingly. LVDS mode selection is static as LVDS panels can't be hot-plugged on any of the device supported by the driver. Support for dynamic mode selection can be implemented in the future when needed. Signed-off-by: Laurent Pinchart

drm: rcar-du: Use the DRM panel API

2017-04-04T14:03:56Z

Instead of parsing the panel device tree node manually, use the panel API to delegate panel handling to a panel driver. Signed-off-by: Laurent Pinchart

drm: rcar-du: Switch to encoder .atomic_mode_set() helper function

2017-04-04T14:03:41Z

The native encoder mode set helper function for atomic drivers is .atomic_mode_set(). Replace the legacy .mode_set() implementation. Signed-off-by: Laurent Pinchart

drm: rcar-du: Remove i2c slave encoder interface for hdmi encoder

2016-07-18T03:28:45Z

The hdmi output in rcar-du uses the i2c slave encoder interface to link to the adv7511 encoder chip. The kms driver creates encoder and connector entities that internally uses the drm_encoder_slave_funcs ops provided by the slave encoder driver. Change the driver such that it expects a bridge entity instead of a slave encoder. The hdmi connector code isn't needed anymore as we expect the adv7511 bridge driver to create/manage the connector. Note that the kms driver still expects a connector node for hdmi to be present in DT. This node has no connection to the connector created by the bridge driver.

drm: rcar-du: Rely on the default ->best_encoder() behavior

2016-06-10T15:24:26Z

All outputs have a 1:1 relationship between connectors and encoders, and the driver is relying on the atomic helpers: we can drop the custom ->best_encoder() implementations and let the core call drm_atomic_helper_best_encoder() for us.
