2016-04-14drm: atmel-hlcdc: support asynchronous atomic commit operationsBoris Brezillon1-1/+93
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>

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).

2015-12-15drm: atmel-hlcdc: add support for sama5d2 SoCsNicolas Ferre1-0/+4
As the hardware description for this chip is the same as the sama5d4, we use this SoC structures for layers and DC descriptions. Thus only 2 lines are added to the atmel_hlcdc_of_match table. The compatible string is already documented in the parent MFD driver's binding.

2015-11-24drm: Pass the user drm_mode_fb_cmd2 as const to .fb_create()Ville Syrjälä1-1/+1
Drivers shouldn't clobber the passed in addfb ioctl parameters. i915 was doing just that. To prevent it from happening again, pass the struct around as const, starting all the way from internal_framebuffer_create().

2015-10-07drm: Stop using drm_vblank_count() as the hw frame counterVille Syrjälä1-1/+1
drm_vblank_count() returns the software counter. We should not pretend it's the hw counter since we use the hw counter to figuere out what the software counter value should be. So instead provide a new function drm_vblank_no_hw_counter() for drivers that don't have a real hw counter. The new function simply returns 0, which is about the only thing it can do.

2015-10-06drm/irq: Use unsigned int pipe in public APIThierry Reding1-2/+4
This continues the pattern started in commit cc1ef118fc09 ("drm/irq: Make pipe unsigned and name consistent"). This is applied to the public APIs and driver callbacks, so pretty much all drivers need to be updated to match the new prototypes.

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.

2015-01-21drm: add Atmel HLCDC Display Controller supportBoris Brezillon1-0/+579
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.
