drm/atomic-helper: Add NO_DISABLE_AFTER_MODESET flag support for plane commit

2016-08-29T09:29:37+00:00

Drivers may set the NO_DISABLE_AFTER_MODESET flag in the 'flags' parameter
of the helper drm_atomic_helper_commit_planes() if the relevant display
controllers(e.g., IPUv3 for imx-drm) require to disable a CRTC's planes
when the CRTC is disabled. The helper would skip the ->atomic_disable
call for a plane if the CRTC of the old plane state needs a modesetting
operation. Of course, the drivers need to disable the planes in their CRTC
disable callbacks since no one else would do that.

drm: Allow drivers to modify plane_state in prepare_fb/cleanup_fb

2016-08-19T08:58:55+00:00

The drivers have to modify the atomic plane state during the prepare_fb
callback so they track allocations, reservations and dependencies for
this atomic operation involving this fb. In particular, how else do we
set the plane->fence from the framebuffer!

    gpu: drm: omapdrm: dss-of: add missing of_node_put after calling of_parse_phandle

The of_get_next_parent will drop refcount on the passed node, so the reverted
patch is wrong, thanks for Tomi Valkeinen points it.

drm: Remove superflous linux/fb.h includes

2016-08-12T08:41:39+00:00

Everyone who uses the fbdev emulation helpers doesn't need to include
fb.h directly. Remove it.

GPU-DRM-OMAP: Delete unnecessary checks before two function calls

2016-07-22T08:27:59+00:00

The following functions test whether their argument is NULL and then
return immediately.
* backlight_device_unregister
* drm_gem_object_unreference_unlocked

Thus the test around the calls is not needed.

This issue was detected by using the Coccinelle software.

Also there's a trivial conflict in ttm_bo.c that git rerere fails to

drm/omap: make fbdev support really optional

2016-07-18T07:11:34+00:00

Currently enabling OMAP DRM support automatically pulls in
fbdev dependency. However this dep is unnecessary since
DRM core already handles this for us (DRM_FBDEV_EMULATION).
