Pull fbdev updates from Florian Tobias Schandinat:
 - large updates for OMAP
   - support for LCD3 overlay manager (omap5)
   - omapdss output cleanup
   - removal of passive matrix LCD support as there are no drivers for
     such panels for DSS or DSS2 and nobody complained (cleanup)
 - large updates for SH Mobile
   - overlay support
   - separating MERAM (cache) from framebuffer driver
 - some updates for Exynos and da8xx-fb
 - various other small patches

video: exynos_dp: use usleep_range instead of delay

2012-07-24T20:56:18+00:00

This patch replaces udelay and mdelay with usleep_range to remove
the busy loop waiting.

video: exynos_dp: check the only INTERLANE_ALIGN_DONE bit during Link Training

2012-07-24T20:55:16+00:00

The only INTERLANE_ALIGN_DONE bit should be checked for channel equalization
during Link Training. Previously, the other bits such as LINK_STATUS_UPDATED
were checked, and channel equalization procedure was repeated unnecessarily.

video: exynos_dp: fix wrong DPCD address during Link Training

2012-07-24T20:54:03+00:00

Wrong DPCD addresses were used for clock recovery during Link Training.
The training pattern should be set by TRAINING_PATTERN_SET (0x102), while
voltage swing and pre-emphasis should be set by TRAINING_LANE0_SET (0x103).

video: backlight: remove unused header

2012-06-24T13:54:52+00:00

Commit 9befe40f6e018e508b047eb76d189ede9b4ff03d ("video: backlight:
support s6e8ax0 panel driver based on MIPI DSI") added s6e8ax0.h, but
no file includes it. That's probably a good thing, because it declares
an extern void function that is defined static int in s6e8ax0.c.
Besides, that function is also wrapped in the module_init() macro, which
should do everything needed to make that function available to the code
outside of s6e8ax0.c. This header can safely be removed.

Some functions are declared twice in header file; thus, these
