2016-04-14drm: atmel-hlcdc: route DMA accesses through AHB interfacesBoris Brezillon
In relation with the actuall bandwidth consumed on a DMA Source interface, choose the less used one for a created plane. 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.

2016-04-14drm: atmel-hlcdc: support extended timing ranges on sama5d4 and sama5d2Boris Brezillon
The display timings on old SoCs older than the sama5d4 are quite limited and prevent the use of many displays. Add support for extended timing ranges on sama5d2 and sama5d4.

2016-04-14drm: atmel-hlcdc: support asynchronous atomic commit operationsBoris Brezillon
drm_atomic_helper_commit() does not support asynchronous commits. Replace it by a specific commit function supporting these kind of requests. Signed-off-by: Boris Brezillon <boris.brezillon@free-electrons.com> Tested-by: Nicolas Ferre <nicolas.ferre@atmel.com>

The only thing this did was cancle pending flip events, and the core takes care of that now.

2015-03-16drm: atmel-hlcdc: use appropriate enabled flag in suspend/resumeSylvain Rochet
Unfortunately we used the enabled flag in struct drm_crtc instead of the enabled flag in struct atmel_hlcdc_crtc. This obviously leads to discrepancies on crtc enable state. This patch fixes the issue by using the struct atmel_hlcdc_crtc enabled flag in PM support.

2015-02-22drm: atmel-hlcdc: add discard area supportBoris Brezillon
The HLCDC IP provides a way to discard a specific area on the primary plane (in case at least one of the overlay is activated and alpha blending is disabled). Doing this will reduce the amount of data to transfer from the main memory to the Display Controller, and thus alleviate the load on the memory bus (since this link is quite limited on such hardware, this kind of optimization is really important).

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.
