drm: Don't swallow error codes in drm_dev_alloc()

2016-09-22T11:03:48+00:00

There are many reasons other than ENOMEM that drm_dev_init() can
fail. Return ERR_PTR rather than NULL to be able to distinguish
these in the caller.

drm: Don't implement empty prepare_fb()/cleanup_fb()

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

The plane .prepare_fb() and .cleanup_fb() helpers are optional, there's
no need to implement empty stubs, and no need to explicitly set the
function pointers to NULL either.

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

2016-07-19T19:33:50+00:00

There is a error message within devm_ioremap_resource
already, so remove the dev_err call to avoid redundant
error message.

drm/arc: Fix some sparse warnings

2016-07-19T19:33:37+00:00

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:

drm/arc: make fbdev support really optional

2016-07-18T07:11:32+00:00

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()

2016-07-18T07:11:29+00:00

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

2016-07-15T12:47:01+00:00

of_node_put needs to be called when the device node which is got
from of_parse_phandle has finished using.

drm/arc: Remove redundant calls to drm_connector_register_all()

2016-06-21T08:53:12+00:00

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

2016-06-15T19:49:32+00:00

- 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. Jon cc'ed as fyi.

drm/arcpgu: Make ARC PGU usable on simulation platforms

2016-06-13T15:45:17+00:00

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.
