This branch contains a largeish set of updates of power management and clock setup. The bulk of it is for OMAP/AM33xx platforms, but also a few around hotplug/suspend/resume on Exynos. It includes a split-up of some of the OMAP clock data into separate files which adds to the diffstat, but gross delta is fairly reasonable. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.11 (GNU/Linux) iQIcBAABAgAGBQJQySrdAAoJEIwa5zzehBx3XBMQAJCgrE/I1vbuiENiVMLpQkN7 0Y5t89SwoALnme5jsM8vW/H0o6b163FfH+249UNs6dyk6MdCqqSv8cQVvSfCKRKn m4JTXS6njSnYgU025klNU9W3FyMuFcgH8b63+c5+sCcqfvdkxrjpNoKqAYNxQlgJ 6DHgHCKZP3JB1e2EFqViw0GJgZIjTNxlWvx8XLcAShSapQ+Ovq/iAcKo41o7ZadB 4zV//VkBMv0TLNTs6SoR0EO8qM+2nIUKE8fgPrRxvvb98tuasKPvlSq9VUeIjnYk kWjNTQYbD1IkrAMPYrwcpLU3xkEr14wrKDBtPK6GdCDcXzdyKq3fzROOXNsqrLmn Y8PkY+J39B59F0DKjyrCjasZyi0tQQV6ps5Xm2X2CB003GWEbo1yu+BodShYEyaL 7OvkLiVpOtq+LOYcsScHtOGdO9le2O3yZevNRvlrCDCvJUYbXNjaM9ZrWcQuTlJc oseYNSRPaIP5PMv2c+Xup9qh/dyAjj8g6gSi9BlDvwVOu/+Cf3laaCAXaFph22jT /m8fW2paiP5UJ0gSt1MLAGFxKi0YI/Qxck8G11LJxUwMZd3SIfOPUAY27tnNC4yL GRynOi3BFRMUAe/Leu2qgwEyoME5nHn+OmAKb36WTYH/HL+PGzHq84e+Wfdan8ha YcSKc1A52LSoYTi4XTUX =h2Qo -----END PGP SIGNATURE----- Merge tag 'pm-merge' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull ARM SoC power management and clock changes from Olof Johansson: "This branch contains a largeish set of updates of power management and clock setup.
