ARM: OMAPFB: panel-sony-acx565akm: fix bad unlock balance

2013-11-26T10:49:17+00:00

When booting Nokia N900 smartphone with v3.12 + omap2plus_defconfig
(LOCKDEP enabled) and CONFIG_DISPLAY_PANEL_SONY_ACX565AKM enabled,
the following BUG is seen during the boot:

[    7.302154] =====================================
[    7.307128] [ BUG: bad unlock balance detected! ]
[    7.312103] 3.12.0-los.git-2093492-00120-g5e01dc7 #3 Not tainted
[    7.318450] -------------------------------------
[    7.323425] kworker/u2:1/12 is trying to release lock (&ddata->mutex) at:
[    7.330657] [] acx565akm_enable+0x12c/0x18c
[    7.335998] but there are no more locks to release!

Fix by removing double unlock and handling the locking completely inside
acx565akm_panel_power_on() when doing the power on.

tree-wide: use reinit_completion instead of INIT_COMPLETION

2013-11-15T00:32:21+00:00

Use this new function to make code more comprehensible, since we are
reinitialzing the completion, not initializing.

Merge tag 'fbdev-3.13' of git://git.kernel.org/pub/scm/linux/kernel/git/tomba/linux

2013-11-14T05:44:20+00:00

Pull fbdev changes from Tomi Valkeinen:
 "Nothing particularly stands out in this pull request.  The biggest
  part of the changes are cleanups.

  Maybe one fix to mention is the "fb: reorder the lock sequence to fix
  potential dead lock" which hopefully fixes the fb locking issues
  reported by multiple persons.

  There are also a few commits that have changes to arch/arm/mach-at91
  and arch/avr32, which have been acked by the maintainers"

OMAPDSS: DSI: fix perf measuring ifdefs

2013-10-29T11:27:06+00:00

DSI performance measuring code is meant to be explicitly enabled at
compile time. At some point in time the perf code was changed to be
enabled if DEBUG is defined. This is not right, so this patch fixes it.

OMAPDSS: Fix de_level in videomode_to_omap_video_timings()

2013-10-18T07:57:43+00:00

In videomode_to_omap_video_timings, de_level is always set to HIGH
regardless of what the vm->flags says. Fix this to set it to high or low
according to vm->flags.

omapdss: HDMI: move common functions to a separate file

2013-10-09T09:42:37+00:00

The OMAP4 HDMI encoder driver(hdmi4.c) contains timings tables, and helper
functions which can be used as is by the OMAP5/DRA7x encoder driver. Move these
to hdmi_common.c so that it's not replicated in the future.
