ARM: SoC non-critical fixes for 3.14
As usual, we have a batch of fixes that weren't considered significant enough to warrant going into the later -rcs for previous release, so they are queued up on this branch. A handful of these are for various DT fixups for Samsung platforms, and a handful of other minor things. There are also a couple of stable-marked patches for mvebu -- they came in quite late and we decided to keep them deferred until the first -stable release to get more coverage instead of squeezing them into 3.13. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.11 (GNU/Linux) iQIcBAABAgAGBQJS4VfEAAoJEIwa5zzehBx3AhIP/RSEQSF66w6/BqYI8qJSFU0g c+4Ubb1i253ayc/bkY43CRVM1iZ9zOFw2O9chogGv6sNmYXOYgJ/R0PQQQyExduK vbi0O+t2rqv+TeD7p3vFyExe1+oppchfDkiS2dTGchWWjqYS2qQnCYjOT4kgC3TA zA2aBZ0oOtpa6OVPG1gAKPyHTwbzoXXkqs1PHpS1hyP0OBMYJl8yhfQfqqs0ZhdJ fHuYjDFnZnLJ8Mm9Ow9XzxzNEioSzYRAwWT/6BY2T6AWixrPTLDZD5RB8d5k5650 O8Od8DyxwHFTSgL+XR1iKaEqe6yd5vYwPmm74Iku/ZlqBQ+7XVEyFHFtOp4xyjy8 dpYho05qTPTkSSQVYC4XO+Vz3G9BPwY4aclUAKONkIYfVQYLWi87WLKjUDY17qVx 9mKAH0f0UP7d00BsVRsM3glSMk1666btySpjDQ8fVlGH9PK1/WiRPh+37q8X9I7I eslUuE3ykJa9i38Taxr+AN3rn0VnvlGEqkzjSDzq9oYERkoyqzYXyz1/SYM1/4kW f6Tc3aQemUeJc50jZ8nVNZja4n9I6ChxySP5JBh1qijlQRef475y8ADa0/mXivS2 Kez5DumlajsesiQTqiGY0CClMQajxbrZTVrfUkrr2UkCEX62YLHIB7TpZtepPYXn TrFoDWZ78CCCPOIC0M8m =QhN9 -----END PGP SIGNATURE----- Merge tag 'fixes-nc-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull ARM SoC non-critical fixes from Olof Johansson: "As usual, we have a batch of fixes that weren't considered significant enough to warrant going into the later -rcs for previous release, so they are queued up on this branch.
