* drm/atmel: Nuke precloseDaniel Vetter2016-02-081-3/+0
| | | | | | | | | | | | The only thing this did was cancle pending flip events, and the core takes care of that now.

* drm: atmel-hlcdc: use appropriate enabled flag in suspend/resumeSylvain Rochet2015-03-161-0/+3
| | | | | | | | | | | | 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.

* drm: atmel-hlcdc: add discard area supportBoris Brezillon2015-02-221-0/+2
| | | | | | | | | | | | | 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).

* drm: add Atmel HLCDC Display Controller supportBoris Brezillon2015-01-211-0/+213
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.
