Should we apply these directly to the arm-soc fixes branch, or wait
until they come back from the Samsung subarchitecture tree?

Hmm, If Kukjin can take in 3.9 rc2 it's better to go via Samsung tree.

Kukjin,

Can you please take this patch in 3.9 rc2 ?

Thanks

Sure, I will.

BTW, Arnd, I'm not sure second one(socfpga.dtsi) can be handled in samsung
tree.

Thanks.

I guess you're right, I've applied the second one to the fixes branch now.
