| | | | | | | | | | | | | | | | | | | | | | | | | | | | Decrementing the reference count of the previous endpoint node allows to use the of_graph_get_next_endpoint function in a for_each_... style macro. All current users of this function that pass a non-NULL prev parameter (that is, soc_camera and imx-drm) are changed to not decrement the passed prev argument's refcount themselves.

* | drm: rcar-du: Fix race condition in hardware plane allocatorLaurent Pinchart2015-03-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The plane allocator has been inherently racy since the beginning of the transition to atomic updates, as the allocator lock is released between free plane check (at .atomic_check() time) and the reservation (at .atomic_update() time). To fix it, create a new allocator solely based on the atomic plane states without keeping any external state and perform allocation in the .atomic_check() handler. The core idea is to replace the free planes bitmask with a collective knowledge based on the allocated hardware plane(s) for each KMS plane. The allocator then loops over all plane states to compute the free planes bitmask, allocates hardware planes based on that bitmask, and stores the result back in the plane states. For this to work we need to access the current state of planes not touched by the atomic update. To ensure that it won't be modified, we need to lock all planes using drm_atomic_get_plane_state(). This effectively serializes atomic updates from .atomic_check() up to completion, either when swapping the states if the check step has succeeded, or when freeing the states if the check step has failed.

* | drm: rcar-du: Move plane commit code from CRTC start to CRTC resumeLaurent Pinchart2015-03-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As the DRM core will commit plane states when performing atomic updates, those don't need to be committed manually when the CRTC is started except in the system resume code path. However, the atomic plane commit step is currently performed between mode set disable and mode set enable to mimick the legacy mode setting operations order. This causes the device clocks to be disabled after applying plane settings and reenabled when enabling the CRTC, potentially losing hardware in between. Reorder the operations to enable the CRTC first and only then apply plane settings, removing the need to manage clocks in the atomic begin and flush handlers. We can then move the plane state commit code out of the CRTC start handler to the system resume handler. Signed-off-by: Laurent Pinchart <laurent.pinchart+renesas@ideasonboard.com>

| | | | | | | | | | | | | | | | | | | | | | The atomic page flip helper implements the page flip operation using asynchronous commits.

* | drm: rcar-du: Handle primary plane config through atomic plane opsLaurent Pinchart2015-03-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Use the new CRTC atomic transitional helpers drm_helper_crtc_mode_set() and drm_helper_crtc_mode_set_base() to implement the CRTC .mode_set and .mode_set_base operations. This delegates primary plane configuration to the plane .atomic_update and .atomic_disable operations, removing duplicate code from the CRTC implementation. There is now no code path available to the driver in which to drop the reference to the CRTC acquired in the .prepare() operation if an error then occurs. The driver thus now leaks a reference if an error occurs during mode set. So be it, this will be fixed in a further step of the atomic update transition.

* | drm: rcar-du: Implement planes atomic operationsLaurent Pinchart2015-03-03

The plane setup code can't be moved out of the CRTC start function completely yet, as the atomic code paths are not taken every time the CRTC needs to be started. This results in some code duplication that will be fixed after switching to atomic updates completely. Signed-off-by: Laurent Pinchart <laurent.pinchart+renesas@ideasonboard.com>
* | drm: rcar-du: Fix hardware plane allocationLaurent Pinchart2015-03-03
| | | | | | | | | | | | | | | | | | | | | | The hardware plane allocator loops over all planes to find free candidates. However, instead of looping over the number of hardware planes, it loops over the number of software planes, which happens to be larger by one unit. This has no effect in practise as the extra plane is always cleared in the mask of free planes, but it should still be fixed for correctness.

* | drm: rcar-du: Disable fbdev emulation when no connector is presentLaurent Pinchart2015-03-03
| | | | | | | | | | | | | | | | | | | | | | | | | | fbdev emulation requires at least one connector, and will fail to initialize if no connector has been successfully instantiated. Disable it in that case and print an informational message instead of failing probe with a confusing fbdev emulation error message. It could be argued that probe should fail when no connector is present, but the DU could still be useful in that case with the to-be-implemented memory write-back support.

* | drm: rcar-du: Turn vblank on/off when enabling/disabling CRTCLaurent Pinchart2015-03-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The DRM core vblank handling mechanism requires drivers to forcefully turn vblank reporting off when disabling the CRTC, and to restore the vblank reporting status when enabling the CRTC. Implement this using the drm_crtc_vblank_on/off helpers. When disabling vblank we must first wait for page flips to complete, so implement page flip completion wait as well. Finally, drm_crtc_vblank_off() must be called at startup to synchronize the state of the vblank core code with the hardware, which is initially disabled. This is performed at CRTC creation time, requiring vertical blanking to be initialized before creating CRTCs. Signed-off-by: Laurent Pinchart <laurent.pinchart+renesas@ideasonboard.com>
* | drm: rcar-du: Wait for page flip completion when turning the CRTC offLaurent Pinchart2015-03-03
