drm/arc: Remove redundant dev_err call in arcpgu_load()

2016-07-19T19:33:50Z

There is a error message within devm_ioremap_resource already, so remove the dev_err call to avoid redundant error message. Signed-off-by: Wei Yongjun Signed-off-by: Sean Paul

drm/arc: Fix some sparse warnings

Fixes the following sparse warnings: drivers/gpu/drm/arc/arcpgu_drv.c:52:5: warning: symbol 'arcpgu_gem_mmap' was not declared. Should it be static? drivers/gpu/drm/arc/arcpgu_drv.c:134:48: warning: Using plain integer as NULL pointer drivers/gpu/drm/arc/arcpgu_drv.c:155:5: warning: symbol 'arcpgu_unload' was not declared.

drm/arc: make fbdev support really optional

2016-07-18T07:11:32Z

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

drm/arcpgu: Delete an unnecessary check before drm_fbdev_cma_hotplug_event()

2016-07-18T07:11:29Z

The drm_fbdev_cma_hotplug_event() function tests whether its argument is NULL and then returns immediately. Thus the test around the call is not needed. This issue was detected by using the Coccinelle software.

gpu: drm: arcpgu_drv: add missing of_node_put after calling of_parse_phandle

drm/arc: Remove redundant calls to drm_connector_register_all()

2016-06-21T08:53:12Z

Up to now, the recommendation was for drivers to call drm_dev_register() followed by drm_connector_register_all(). Now that drm_connector_register() is safe against multiple invocations, we can move drm_connector_register_all() to drm_dev_register() and not suffer from any backwards compatibility issues with drivers not following the more rigorous init ordering.

Merge tag 'topic/drm-misc-2016-06-15' of git://anongit.freedesktop.org/drm-intel into drm-next

2016-06-15T19:49:32Z

- best_encoder cleanup from Boris. - drm_simple_display_pipe helpers from Noralf. Looks really neat imo, and there's 2-3 in-flight drivers which look like they could/should use it. Anyway, with this we have now helpers and everything in place to write drivers for simple hw with fewer complexity in the driver than what fbdev would need. That was the last complaint I've heard from embedded folks after we made atomic happen. Mission accomplished! - nonblocking commit helpers for atomic, plus a bunch of driver patches for that. - Prep patch from Laurent for cleaned up pixel format functions. - More of Gustavo's cleanup for drm vblank functions. - and a few oddball things in between Plus the merge of docs-next to prep the docbook->sphinx conversion as discussed.

drm/arcpgu: Make ARC PGU usable on simulation platforms

2016-06-13T15:45:17Z

In case of simulation there's no real encoder/transmitter device because in the model's virtual LCD we're rendering whatever appears in frame-buffer memory. Signed-off-by: Ruud Derwig Signed-off-by: Alexey Brodkin Acked-by: Daniel Vetter

drm: arc: Rely on the default ->best_encoder() behavior

2016-06-10T15:21:52Z

We have a 1:1 relationship between connectors and encoders and the driver is relying on the atomic helpers: we can drop the custom ->best_encoder(), and let the core call drm_atomic_helper_best_encoder() for us.

drm/arc: Implement nonblocking commit correctly

2016-06-10T15:11:17Z

Committing with block it is not. Thanks to the fixed up vblank event handling we can just use the helper support for nonblocking commits now.
