| | | | | | | | | | | | | | | | | | If PM is enabled but PM_SLEEP is disabled, the suspend/resume functions are still unused and produce a compiler warning.

* | drm/atomic: pass old crtc state to atomic_begin/flush.Maarten Lankhorst2015-07-271-2/+4
|/ | | | | | | | | | | | In intel it's useful to keep track of some state changes with old crtc state vs new state, for example to disable initial planes or when a modeset's prevented during fastboot.

* drm: atmel-hlcdc: use appropriate enabled flag in suspend/resumeSylvain Rochet2015-03-163-15/+28
| | | | | | | | | | | | 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: reset layer A2Q and UPDATE bits when disabling itBoris Brezillon2015-02-241-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | The A2Q (Add To Queue) and UPDATE bits are left in their previous state when resetting the layer. This lead to weird behavior when enabling the plane again: the framebuffer previously queued is dequeued and we end up with access to an old memory region. Reset those bits when resetting the channel. Signed-off-by: Boris Brezillon <boris.brezillon@free-electrons.com>
* | drm: Pass in new and old plane state to prepare_fb and cleanup_fbTvrtko Ursulin2015-03-051-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Use cases like rotation require these hooks to have some context so they know how to prepare and cleanup the frame buffer correctly. For i915 specifically, object backing pages need to be mapped differently for different rotation modes and the driver needs to know which mapping to instantiate and which to tear down when transitioning between them. v2: Made passed in states const.

* | drm: atmel-hlcdc: add discard area supportBoris Brezillon2015-02-223-1/+111
| | | | | | | | | | | | | | | | | | | | | | | | | | 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 Brezillon2015-01-219-0/+3456
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.
