ARM: SoC fixes for 3.17
Here's our last set of fixes for 3.17. Most of these are for TI platforms, fixing some noisy Kconfig issues, runtime clock and power issues on several platforms and NAND timings on DRA7. There are also a couple of bug fixes for i.MX, one for QCOM and a small fix to avoid section mismatch noise on PXA. Diffstat looks large, partially due to some tables being updated and thus touching many lines. The qcom gsbi change also restructures clock management a bit and thus touches a bunch of lines. All in all, a bit more changes than we'd like at this point, but nothing stands out as risky either so it seems like the right thing to send it up now instead of holding it to the merge window. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.14 (GNU/Linux) iQIcBAABAgAGBQJUJxVMAAoJEIwa5zzehBx3VVoP/3WeftI/+vncYhMmPCaUxOso B/rNY1CW2ZYr9yWEvREQtMQCkLWYPifeyHa+fXHeFfLGWlMP1wU4LP78RrvaMnSs V0d2wYmfTkSIlVwqRMuArY9KwnOTRSiDfhQpl2BQ84u1IaZM5/IRw9oNICTao8jI A7NsLAnss3exKCT06R3CcG7+fq3zVc19aI1QJG61BFqTIVItf71NTm/lcjsL3Tss Tr/ITTgZM6UGkEnTUuRCl3gpMn/TVvO/qE94xU6vY0jqDQKUl1cxUCx6gRcSDRu4 PvLvPS7d4p99dHmLxVUuLBT7AGtRCxfdAoVE3D3rmGfcthDt1nFBgJfp6ekQZAM9 ZfJnrvfHRLjl/lxQvWWkpuugu0z7GCFeXRFHN6aLsD6aRD4JmYoRuSeA0aXmTKyp oDcduXqYOImTcbUQ8G8n1YeK8BAVlL6PEZKvaIhjmxUWHVeGdpesz9s7TFBqGBBd F1EeCPtAczBpNJP4E/dRDzWYjp+lGyQs4dQEU+YpRe9drzJpw6GsDuaF78QP8A5a TEcc3y3o2FSNbGCw9qQ7pkgm76aS1YhLKMQb+2JXJptgwKMw3G6abMr+iomlm3Id DY8+WIBggx/gB5k/onFseZvjNxVKqQUeh31UT5e1v/9M4bCJvEcY+KeKcgjbPpy7 GnGoXEvCnwZ7kPokqH0D =K6xV -----END PGP SIGNATURE----- Merge tag 'fixes-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull ARM SoC fixes from Olof Johansson: "Here's our last set of fixes for 3.17.
