wrappers for ->i_mutex access

2016-01-22T23:04:28+00:00

parallel to mutex_{lock,unlock,trylock,is_locked,lock_nested},
inode_foo(inode) being mutex_foo(&inode->i_mutex).

Please, use those for access to ->i_mutex; over the coming cycle
->i_mutex will become rwsem, with ->lookup() done with it held
only shared.

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/)"

video: fbdev: pxafb: fix out of memory error path

2016-01-18T08:26:17+00:00

As seen by Julia, the initial allocation memory is not checked anymore
after commit "video: fbdev: pxafb: initial devicetree conversion".
Introduce back the removed test.

video: fbdev: via: use gpiochip data pointer

2016-01-06T23:02:34+00:00

This makes the driver use the data pointer added to the gpio_chip
to store a pointer to the state container instead of relying on
container_of().

fbdev: via-gpio: Be sure to clamp return value

2016-01-05T09:28:03+00:00

As we want gpio_chip .get() calls to be able to return negative
error codes and propagate to drivers, we need to go over all
drivers and make sure their return values are clamped to [0,1].
We do this by using the ret = !!(val) design pattern.

drm/omap: move omapdss & displays under omapdrm

2015-12-29T09:07:48+00:00

Now that omapfb has its own copy of omapdss and display drivers, we can
move omapdss and display drivers which omapdrm uses to omapdrm's
directory.

We also need to change the main drm Makefile so that omapdrm directory
is always entered, because omapdss has a file that can't be built as a
module.

omapfb: move vrfb into omapfb

2015-12-29T09:07:47+00:00

VRFB is only used by omapfb, so we can move it under omapfb's directory.

omapfb: take omapfb's private omapdss into use

2015-12-29T09:07:47+00:00

omapfb's private copy of omapdss is now ready to be used.

This patch makes omapfb use its private omapdss and display drivers, and
also makes omap_vout (which uses omapfb) to depend on omapfb.

omapfb/displays: change CONFIG_DISPLAY_* to CONFIG_FB_OMAP2_*

2015-12-29T09:07:47+00:00

We need to change the config symbols of omapfb's private copy of the
panel and encoder drivers so that we won't have config symbol conflicts.

This patch changes the symbols from the panel and encoder drivers using
simple replacement of DISPLAY_* to FB_OMAP2*.
