The chance is quickly slipping away because we're going to be at -rc1
soon. I'm not the one to decide what is and isn't being used by people
out there, so I'm happy to apply this patch now before the next -rc1
comes out as long as it doesn't break anything in arm-soc area. The
confidence I'm getting isn't high though. Has anyone from NXP reviewed
this change? Maybe I can get an ack from someone else that normally
looks after the arm-soc/dts side of things here indicating that nothing
should go wrong? That would increase my confidence levels.
