2016-12-18drm: bridge: Link encoder and bridge in core codeLaurent Pinchart
Instead of linking encoders and bridges in every driver (and getting it wrong half of the time, as many drivers forget to set the drm_bridge encoder pointer), do so in core code. The drm_bridge_attach() function needs the encoder and optional previous bridge to perform that task, update all the callers.

2016-06-21drm: atmel-hlcdc: Fix OF graph parsingBoris Brezillon
atmel_hlcdc_create_outputs() iterates over OF graph nodes and releases the node (using of_node_put()) after each iteration, which is wrong since for_each_endpoint_of_node() is already taking care of that. Move the of_node_put() call in the error path.

2016-06-10drm: atmel-hlcdc: Rely on the default ->best_encoder() behaviorBoris Brezillon
We 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() and let the core call drm_atomic_helper_best_encoder() for us.

The current output code only supports connection to drm panels. First simplify the drm panel code, and then add support for external drm bridges. Signed-off-by: Boris Brezillon <boris.brezillon@free-electrons.com> Tested-by: Nicolas Ferre <nicolas.ferre@atmel.com>
2016-04-14drm: atmel-hlcdc: move output mode selection in CRTC implementationBoris Brezillon
In order to support multiple outputs we need to move the output mode selection to the CRTC object, so that the output validity check can be done against the drm_atomic_state. If the connectors selected by a specific mode setting are requiring incompatible bus format the atomic operation is aborted (->atomic_check() returns -EINVAL). In order to implement that, we need to define our own CRTC state and overload default ->reset(), ->atomic_duplicate_state() and ->atomic_destroy_state() functions.

2015-01-21drm: add Atmel HLCDC Display Controller supportBoris Brezillon
The Atmel HLCDC (HLCD Controller) IP available on some Atmel SoCs (i.e. at91sam9n12, at91sam9x5 family or sama5d3 family) provides a display controller device. This display controller supports at least one primary plane and might provide several overlays and an hardware cursor depending on the IP version. At the moment, this driver only implements an RGB connector to interface with LCD panels, but support for other kind of external devices might be added later.
