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: 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: 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: Don't include in

2016-12-18T10:59:29Z

used to define most of the in-kernel KMS API. It has now been split into separate files for each object type, but still includes most other KMS headers to avoid breaking driver compilation. As a step towards fixing that problem, remove the inclusion of from and include it instead where appropriate. Also remove the forward declarations of the drm_encoder and drm_encoder_helper_funcs structures from as they're not needed in the header. now has to include and contain a forward declaration of struct drm_encoder in order to allow including it as the first header in a compilation unit.

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.

drm: rcar-du: Add HDMI encoder and connector support

drm: rcar-du: Replace drm_encoder with drm_slave_encoder

2014-11-26T18:09:38Z

DRM slave encoders require their associated struct drm_encoder instance to be embedded in a struct drm_slave_encoder. This makes processing encoders regardless of their types needlessly and painfully complex in drivers that use a mix of slave encoders and custom encoders. Such a driver will need to either create drm_slave_encoder instances that fake their embedded encoder instance, or to turn all drm_encoder instances into drm_slave_encoder instances. Between the two evils, one must choose the lesser. Use drm_slave_encoder everywhere. Signed-off-by: Laurent Pinchart

drm: rcar-du: Replace direct DRM encoder access with cast macro

2014-11-26T18:09:37Z

Add a new macro to downcast an rcar_du_encoder pointer to a drm_encoder pointer and use it. This prepares for the replacement of the rcar_drm_encoder encoder field with a drm_slave_encoder. Signed-off-by: Laurent Pinchart
