People are back from the holiday breaks, and it shows. Here are a bunch of
fixes for a number of platforms:
- A couple of small fixes for Nomadik
- A larger set of changes for kirkwood/mvebu
- uart driver selection, dt clocks, gpio-poweroff fixups,
a few __init annotation fixes and some error handling improvement
in their xor dma driver.
- i.MX had a couple of minor fixes (and a critical one for flexcan2
clock setup)
- MXS has a small board fix and a framebuffer bugfix
- A set of fixes for Samsung Exynos, fixing default bootargs and some
Exynos5440 clock issues
- A set of OMAP changes including PM fixes and a few sparse warning
fixups
All in all a bit more positive code delta than we'd ideally want to see
here, mostly from the OMAP PM changes, but nothing overly crazy.

The VDCTRL4 register does not provide the MXS SET/CLR/TOGGLE feature.
The write in mxsfb_disable_controller() sets the data_cnt for the LCD
DMA to 0 which obviously means the max. count for the LCD DMA and
leads to overwriting arbitrary memory when the display is unblanked.

CONFIG_HOTPLUG is going away as an option. As a result, the __dev*
markings need to be removed.
This change removes the use of __devinit, __devexit_p, __devinitdata,
__devinitconst, and __devexit from these drivers.
Based on patches originally written by Bill Pemberton, but redone by me
in order to handle some of the coding style issues better, by hand.

Add a simple device tree probe support for mxsfb driver. Before
a common binding for struct fb_videomode is available, the driver will
keep using struct mxsfb_platform_data. That said, platform code will
use auxdata to attach mxsfb_platform_data for device tree boot.

The driver should be registered with mxsfb_driver, not with mxsfb_devtype.

changes since v2:
- use v3 and v4 for specifying the ip version instead of i.MX23/28.
This is a better namespace when future versions are added.
- rename mach/fb.h to mach/mxsfb.h
changes since v1:
- Add a LCDC_ prefix to the register names.
- use set/clear registers where appropriate
- protect call to mxsfb_disable_controller() in mxsfb_remove()
with a (host->enabled) as suggested by Lothar Wassmann
