Linus Torvalds d4e1f5a14e ARM: SoC device-tree changes for 3.17 
Unlike the board branch, this keeps having large sets of changes for
 every release, but that's quite expected and is so far working well.
 
 Most of this is plumbing for various device bindings and new platforms,
 but there's also a bit of cleanup and code removal for things that
 are moved from platform code to DT contents (some OMAP clock code in
 particular).
 
 There's also a pinctrl driver for tegra here (appropriately acked),
 that's introduced this way to make it more bisectable.
 
 I'm happy to say that there were no conflicts at all with this branch
 this release, which means that changes are flowing through our tree as
 expected instead of merged through driver maintainers (or at least not
 done with conflicts).
 
 There are several new boards added, and a couple of SoCs. In no particular
 order:
 
 * Rockchip RK3288 SoC support, including DTS for a dev board that they
   have seeded with some community developers.
 * Better support for Hardkernel Exynos4-based ODROID boards.
 * CCF conversions (and dtsi contents) for several Renesas platforms.
 * Gumstix Pepper (TI AM335x) board support
 * TI eval board support for AM437x
 * Allwinner A23 SoC, very similar to existing ones which mostly has
   resulted in DT changes for support. Also includes support for an Ippo
   tablet with the chipset.
 * Allwinner A31 Hummingbird board support, not to be confused with the
   SolidRun i.MX-based Hummingboard.
 * Tegra30 Apalis board support
