dma-mapping: always provide the dma_map_ops based implementation

2016-01-21T01:09:18+00:00

Move the generic implementation to  now that all
architectures support it and remove the HAVE_DMA_ATTR Kconfig symbol now
that everyone supports them.

Merge tag 'fbdev-4.5' of git://git.kernel.org/pub/scm/linux/kernel/git/tomba/linux

2016-01-18T19:58:31+00:00

Pull fbdev updates from Tomi Valkeinen:
 "Summary:

   - pxafb: device-tree support
   - An unsafe kernel parameter 'lockless_register_fb' for debugging
     problems happening while inside the console lock
   - Small miscellaneous fixes & cleanups
   - omapdss: add writeback support functions
   - Separation of omapfb and omapdrm (see below)

  About the separation of omapfb and omapdrm, see

    http://permalink.gmane.org/gmane.comp.video.dri.devel/143151

  for longer story.  The short version:

  omapfb and omapdrm have shared low level drivers (omapdss and panel
  drivers), making further development of omapdrm difficult.  After
  these patches omapfb and omapdrm have their own versions of the
  drivers, which are more or less direct copies for now but will diverge
  soon.

  This also means that omapfb (everything under drivers/video/fbdev/omap2/)
  is now in maintenance mode, and all new development will be done for
  omapdrm (drivers/gpu/drm/omapdrm/)"

[media] call media_device_init() before registering the V4L2 device

2016-01-11T14:19:25+00:00

Currently, v4l2_device_register() doesn't use the media_device
struct. So, calling media_device_init() could be called either
before or after v4l2_device_register().

Yet, it is a good practice to initialize everything before calling
the register functions. Also, the other drivers call
media_device_init() before registering the V4L2 device.

So, move the call for media_device_init() to happen earlier on
exynos4-is and s3c-camif.

This is just a cleanup patch.

[media] media-device: split media initialization and registration

2016-01-11T14:19:15+00:00

The media device node is registered and so made visible to user-space
before entities are registered and links created which means that the
media graph obtained by user-space could be only partially enumerated
if that happens too early before all the graph has been created.

To avoid this race condition, split the media init and registration
in separate functions and only register the media device node when
all the pending subdevices have been registered, either explicitly
by the driver or asynchronously using v4l2_async_register_subdev().

The media_device_register() had a check for drivers not filling dev
and model fields but all drivers in mainline set them and not doing
it will be a driver bug so change the function return to void and
add a BUG_ON() for dev being NULL instead.

Also, add a media_device_cleanup() function that will destroy the
graph_mutex that is initialized in media_device_init().
