While I agree this is good idea for mainline (thus my ack), I don't
think it is suitable for stable, as older kernels will not run on OLPC
in useful way, anyway.

Not-acked-for-stable-by: Pavel Machek <pavel@....cz>

So I don't think this and ARM: dts: mmp2: fix TWSI2 is good idea for
stable kernels.
