Hi Kukjin,
Are you aware that `make dtbs` fails on your for-next branch (4533046)?
DTC arch/arm/boot/dts/exynos5420-peach-pit.dtb
arch/arm/boot/dts/exynos5420-peach-pit.dts:447:33: fatal error:

On https://patchwork.kernel.org/patch/4297431/ Doug had pointed out that
a topic branch merge would be needed for cros-ec-keyboard.dtsi (which I
also pointed out for my spring series). Can you please fix this through
some merge? Your affected branch is v3.17-next/dt-samsung with "ARM:
dts: Add cros_ec to exynos5420-peach-pit and exynos5800-peach-pi".
There's a topic branch in the Tegra tree:
http://git.kernel.org/cgit/linux/kernel/git/tegra/linux.git/log/?h=for-3.17/dt-cros-ec-kbd
and it's been merged into arm-soc recently.
https://git.kernel.org/cgit/linux/kernel/git/arm/arm-soc.git/tree/arch/arm/boot/dts?h=for-next
Also, I've run into some boot regressions:
On the Arndale Octa (5420) I see an asynchronous external abort on
serial console when systemd gets started.

On the Spring Chromebook (5250) the screen goes dark after a few lines,
and USB is not initialized. Thus unclear to me why.
On the ODROID-XU (with local patches based on smdk5410) I get the
following with earlyprintk:

Reverting "ARM: EXYNOS: Refactored code for using PMU address via DT"
and "ARM: EXYNOS: Add support for mapping PMU base address via DT" fixed
the latter.
Anyone know what might cause the others and how to fix?
Thanks,
Andreas
