Please keep nodes with a unit address sorted numerically by unit
address.  0x17014000 should not come before 0xc263000

Presumably this is the kind of thing that Andy can fix himself when he
lands stuff (often dts stuff ends up conflicting a bunch anyway), so I
wouldn't personally post another patch unless I hear from him that he
wants you to repost.  ...but please keep it in mind for the future.

In any case:
