The bulk of this branch is updates for Renesas Shmobile. They are still doing some enablement for classic boards first, and then come up with DT bindings when they've had a chance to learn more about the hardware. Not necessarily a bad way to go about it, and they're looking at moving some of the temporary board code resulting from it to drivers/staging instead to avoid the churn here. As a result of the shmobile clock cleanups, we end up merging quite a bit of SH code here as well. We ended up merging it here instead of in the cleanup branch due to the other board changes depending on it. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.14 (GNU/Linux) iQIcBAABAgAGBQJTjNClAAoJEIwa5zzehBx3Q7wP+wYzWTAU0+3BnnjJpQM79hsX 1hP89RaM6DEyTf6PiL/AKOHsnDponUhNzZu1W5FvNG6cFVenh/nxbmO65FKX9CrY Ap2pkQW+/IcpmIKZ+Hln2bkCc54a6yPouK+5pd9W14X5TtqNmLbdh1qhoq9UjFTo zgLfhch5tyNqfpNOj0vFsmvTw0ZGJ0Neq6olRqQbXmyAaRaWzDa64lmEKVupMdk7 2Fh/8jeXlVlryi7p7CvNoAmZEMm7+We5ZMVsQXLk8b9zcwuCWK0DZzNW4DnRCB1d lsNM/Sygi3Y5zRj2XogNANVhNDIih0f50FX7uuKtmevWNJE9n4To7uFUMTk/3zBt 1hvJLL8w4WHhzkg5v5nFsiCTx65pFaTD/LocPj8lhQ1AYzUvWN5sKPxW0uC1lvJ9 Unlwdc0C4EWs3yq6hAPUZS2eB7owmzNUWdjdkgKfdc74u5RnRay0pUmbRMJm2l20 OKoDSwaluQZUeHrxPnTSLdgpkBbPRn9M5DbswEQsuPyI6yROgCRxaRQ4XcpM93dV 4obCF+fOvX6dtsdIUBCtdhvmJ/iHqhQlPLc2avpt2gyti7eWjQkt5it12hjjOF6A DVBdNHv215EEgvB0MbPJvFVKBLw4boxdeBx+FqMQCqvAbqefHo4gcQZcsUGAv/pX zJ8jgkYhlt7XTd+6GlJu =lWof -----END PGP SIGNATURE----- Merge tag 'boards-for-3.16' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc into next Pull ARM SoC board support updates from Olof Johansson: "The bulk of this branch is updates for Renesas Shmobile.
