* | drm/arcpgu: Make ARC PGU usable on simulation platformsRuud Derwig2016-06-134-8/+138
|/ | | | | | | | | | In case of simulation there's no real encoder/transmitter device because in the model's virtual LCD we're rendering whatever appears in frame-buffer memory.

| * drm/fence: add fence to drm_pending_eventGustavo Padovan2016-06-031-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Now a drm_pending_event can either send a real drm_event or signal a fence, or both. It allow us to signal via fences when the buffer is displayed on the screen. Which in turn means that the previous buffer is not in use anymore and can be freed or sent back to another driver for processing. v2: Comments from Daniel Vetter - call fence_signal in drm_send_event_locked() - remove unneeded !e->event check v3: Remove drm_pending_event->destroy to fix a leak when e->file_priv is not set.

* drm/arcpgu: use dedicated memory area for frame bufferAlexey Brodkin2016-04-291-0/+6
| | | | | | | | | | | | | | | | | Now when ARC supports reserved memory areas and per-device coherent DMA allocations we may switch ARC PGU to use of those dedicated areas. One of the benefits we may move frame-buffer area out from IO Coherency aperture and so significantly reduce IOC utilization allowing less demanding peripherals to use all perks of IOC.

* drm: Add support of ARC PGU display controllerCarlos Palminha2016-04-267-0/+842
ARC PGU could be found on some development boards from Synopsys. This is a simple byte streamer that reads data from a framebuffer and sends data to the single encoder.
