ARM: SoC: late cleanups
These could not be part of the first cleanup branch, because they either came too late in the cycle, or they have dependencies on other branches. Important changes are: * The integrator platform is almost multiplatform capable after some reorganization (Linus Walleij) * Minor cleanups on Zynq (Michal Simek) * Lots of changes for Exynos and other Samsung platforms, including further preparations for multiplatform support and the clocks bindings are rearranged. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.12 (GNU/Linux) iQIVAwUAUz/2IGCrR//JCVInAQI+sA//baZOXHTNRR7uBh5PJgaDFIyNjtBDDyyB m+yYgw24n3WP1YWtFhBKza7p5Eh2spWYgffKV/logWM4SC3HjkCUsLkQwruHa2qe H/pCknUXqUNiwH76WVbfrABb+0tARjEB+U0QfXh7af7Zk+ZXMqQ1/ItU0YdpJiGO mOAI5c6gzpr953cmzuHer8foATmF5DNuJPhPDPYlgeg2+yvXgcnfi9a+AXE8Eqb1 sZeWUJrqJERBlmsVgihq1+gPJjh0Kw7D9r835JqQeKRnywFgvGbmf5kYriPiEEBt hJUUnRHW6GCFQM9MemP0nOaRQlQYJA+EPqzB+0YRps0Gq+3QCIXFzZwLije/eMvr 2YjpITS2MaTqvag1o4yNmfeG+hGMN6MgbOh9q5kLagTXn/9nsQ6aYkD9tCXw4G08 bH3PP90AT6jQoNDoac5Pt2xPBPvY1JnnUegw5YmQQAlKeSEaiSJnHaC4gD9jzy7q fvoXey/Fz/ZgtZKL0wjbjhUrurS45xqZUW0MlMFOt6U7wdG4wsuemaI2PID6tKp8 ZmZ5gyHsX+CK4GfmhFFu3XhM8hyRj3/OBSy0/Wls3znFH/6j/X1gvrH87gnS9+ax +Ettut5uCutDaUJRymXDlqdF9ysLC3DVHpofQPSCqVZ+IHQkUadypyc6YY1Z5mtQ x/nxniFA7/A= =1i9x -----END PGP SIGNATURE----- Merge tag 'tags/cleanup2-3.15' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull ARM SoC late cleanups from Arnd Bergmann: "These could not be part of the first cleanup branch, because they either came too late in the cycle, or they have dependencies on other branches.
