drm: rcar-du: Drop local encoder variable

2021-01-05T05:20:10Z

The local encoder variable is an alias for &renc->base, and is only use twice. It doesn't help much, drop it, along with the rcar_encoder_to_drm_encoder() macro that is then unused. Signed-off-by: Laurent Pinchart Reviewed-by: Jacopo Mondi Reviewed-by: Kieran Bingham

drm: rcar-du: Simplify encoder registration

2019-02-08T00:25:55Z

Before the driver fully moved to drm_bridge and drm_panel, it was necessary to parse DT and locate encoder and connector nodes. The connector node is now unused and can be removed as a parameter to rcar_du_encoder_init(). As a consequence rcar_du_encoders_init_one() can be greatly simplified, removing most of the DT parsing.

drm: rcar-du: Remove inclusion of drmP.h

2019-01-14T01:51:33Z

The DRM kernel API used to be defined in a handful of headers, pulled in through drmP.h. It has since been split in multiple headers for the different DRM components, and drmP.h turned into a legacy header that just pulls in most of the DRM kernel API (and a large number of other miscellaneous kernel headers). In order to speed up compilation, replace inclusion of drmP.h with only the required headers. It turns out that the rcar-du-drm driver already includes most of the necessary headers, so the change is simple. While at it, remove unneeded inclusion of other headers, and unneeded forward declarations of structures. Signed-off-by: Laurent Pinchart Acked-by: Daniel Vetter Reviewed-by: Kieran Bingham

drm: rcar-du: Convert to SPDX identifiers

2018-09-14T10:54:03Z

Kconfig doesn't have license line, thus, it is GPL-2.0 as default. rcar_du_regs.h, rcar_lvds_regs.h are GPL-2.0, and all other files are GPL-2.0+ as original license. Signed-off-by: Kuninori Morimoto Acked-by: Laurent Pinchart Reviewed-by: Simon Horman Signed-off-by: Laurent Pinchart

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.
