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 -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.14 (GNU/Linux) iQIcBAABAgAGBQJT5DqvAAoJEIwa5zzehBx3tm0QAJk8zFyZuMhUPz6SoZTtO9ti zojZ2218oqLRDfLSYdJx/3QE7gb2ef0e2S6FrthecdAY8sqZzDddL7M/cCf1WSgy +D4dD1UEq+W/hOeEwIWyo3GR/71exgo/LMTIw8HOJh5c9fanQ2wNChNetCgh8b4u sVOEMmP1UTO2W7mH9cCRhWXFifBNi0yNl1QBYnLPzM2CbSEa4qQRarTn/94NSEiY U9XgzysklvYEW/30wcEkz8ZonKbJrtP+zEjODU4wN/muhHECeTehDrkJq0WEK/3C 3ptko2xQGURNaLM6HVvQS9qkXxyhCeZxqkELpjkjjM+YPFN8wdHu7gDctGZlDr39 LQ2pZF6K8vaFvxp3UM2wzdDeoNi3rxguzpFoBmfRP5NWguDrOvjT3w8W4hO9q04J 8SqMGca0av9myHmeSjtRRg5rmcC3kBbOgSN6siVJ8W80rHT7tnFjl6eCawDreQzn szFzGaOOUnf/kJ/00vzm1dCuluowFPdSYgW3aamZhfkqu2qYJ8Ztuooz5eZGKtex zlUfKtpL26gnamoUT42K7E8J968AjHjUc/zimwYzIgHCzTTApYGJQcbD/Y28b8QH gTvhRxP+0kFb+NNq4IHStVMvJrFOPvzOHXcL8x07HqTxrl7W4XoW+KJxCJOk433W 5NJ9s4tEmiTRMtFL1kv6 =xxlY -----END PGP SIGNATURE----- Merge tag 'dt-for-3.17' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull ARM SoC device-tree changes from Olof Johansson: "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.
