* drm: rcar-du: Convert LVDS encoder code to bridge driverLaurent Pinchart2018-03-071-160/+15Star
| | | | | | | | | | | 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_nameRob Herring2017-07-261-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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_NONELaurent Pinchart2017-04-041-21/+9Star
| | | | | | | | | | 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 <laurent.pinchart+renesas@ideasonboard.com>
* drm: rcar-du: Replace manual bridge implementation with DRM bridgeLaurent Pinchart2017-04-041-45/+59
| | | | | | | The rcar-du driver contains a manual implementation of HDMI and VGA bridges. Use DRM bridges to replace it. Signed-off-by: Laurent Pinchart <laurent.pinchart+renesas@ideasonboard.com>
* drm: rcar-du: Add support for LVDS mode selectionLaurent Pinchart2017-04-041-0/+27
| | | | | | | | | 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.

* drm: rcar-du: Remove i2c slave encoder interface for hdmi encoderArchit Taneja2016-07-181-2/+1Star
| | | | | | | | | | | | | | | | | | 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: Replace encoder mode_fixup with atomic_checkLaurent Pinchart2015-03-031-23/+12Star

* drm: rcar-du: Clamp DPMS states to on and offLaurent Pinchart2014-12-231-0/+3
| | | | | | | | | | | The intermediate DPMS standby and suspend states are a thing from the past. They only matter in practice for VGA CRT monitors, and are just a power saving vs. resume time optimization. Given that they have never been implemented properly in the rcar-du driver and that the Intel driver has dropped them on the vga port years ago, it's safe to only care about the on and off states.

Don't propagate the error out of the probe function but just skip the failed encoder. As a special case a deferred probe request from the encoder is still propagated out of the probe function in order not to break the deferred probing mechanism.

The DU has 5 possible outputs (DPAD0/1, LVDS0/1, TCON). SoC-internal output routing data specify which output are valid, which CRTCs can be connected to the valid outputs, and the type of in-SoC encoder for the output.
