2016-04-14drm: atmel-hlcdc: support extended timing ranges on sama5d4 and sama5d2Boris Brezillon2-6/+24
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.

2015-12-15drm: use dev_name as default unique name in drm_dev_alloc()Nicolas Iooss1-4/+0
The following code pattern exists in some DRM drivers: ddev = drm_dev_alloc(&driver, parent_dev); drm_dev_set_unique(ddev, dev_name(parent_dev)); (Sometimes dev_name(ddev->dev) is used, which is the same.) As suggested in http://lists.freedesktop.org/archives/dri-devel/2015-December/096441.html, the unique name of a new DRM device can be set as dev_name(parent_dev) when parent_dev is not NULL (vgem is a special case).
