Is the lid switch not working?
Where is your pinctrl?
Can you match this in sort order with snow to make diffs easier?

I think you want a pinctrl for gpx1-6, like Snow's "ec_irq".

mmc_1 on Spring matches with mmc_3 on Snow. That means you need to
make sure you've got the reduced drive strengths, too. I don't think
your device tree has these. Specifically you need local overrides of
sd1_clk, sd1_cmd, etc to lower drive strengths.

Remove the mmc_2 reference. It's disabled in exynos5250.dtsi already.

Ideally you could do one more cleanup patch to snow first to make
diffs easier between the two dts files. Moving things in the snow
file from "pinctrl@11400000" to the pinctrl_0 section would help.
...and other cleanups you could do to snow to make diffs similar would
also be really great.
