Merge tag 'boards' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull "ARM: board specific updates" from Arnd Bergmann/Olof Johansson:
"These changes are all specific to one board only. We're trying to
keep the number of board files low, but generally board level updates
are ok on platforms that are working on moving towards DT based
probing, which will eventually lead to removing them.
The board-ams-delta.c board file gets a conflict between the removal
of ams_delta_config and the addition of a lot of other data. The
Kconfig file has two changes in the same line, and in exynos, the
power domain cleanup conflicts with the addition of the image sensor
device.
Signed-off-by: Arnd Bergmann <arnd@arndb.de>
[olof: Amended a fix for a mismerge to board-omap4panda.c]
Signed-off-by: Olof Johansson <olof@lixom.net>"
Fixed up some fairly trivial conflicts manually.
