These changes are all to SoC-specific code, a total of 33 branches on 17 platforms were pulled into this. Like last time, Renesas sh-mobile is now the platform with the most changes, followed by OMAP and EXYNOS. Two new platforms, TI Keystone and Rockchips RK3xxx are added in this branch, both containing almost no platform specific code at all, since they are using generic subsystem interfaces for clocks, pinctrl, interrupts etc. The device drivers are getting merged through the respective subsystem maintainer trees. One more SoC (u300) is now multiplatform capable and several others (shmobile, exynos, msm, integrator, kirkwood, clps711x) are moving towards that goal with this series but need more work. Also noteworthy is the work on PCI here, which is traditionally part of the SoC specific code. With the changes done by Thomas Petazzoni, we can now more easily have PCI host controller drivers as loadable modules and keep them separate from the platform code in drivers/pci/host. This has already led to the discovery that three platforms (exynos, spear and imx) are actually using an identical PCIe host controller and will be able to share a driver once support for spear and imx is added. Conflicts: * asm/glue-proc.h has one CPU type getting added that conflicts with another addition in 3.10-rc7 * Simple context changes in arch/arm/Makefile and arch/arm/Kconfig -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.12 (GNU/Linux) iQIVAwUAUdLnpmCrR//JCVInAQLoFRAAyatR+MhVFwc91cO7yDw/mz81RO1V9jEd QMufoWi0BRfBsubqxnGlb510EEMTz7gxdrlYPILYNr8TqR+lNGhjKt2FQAjN3q2O IBvu4x8C+xcxnMNbkCnTQRxP/ziK6yCI6e7enQhwuMuJwvsnJtGbsqKi5ODMw6x0 o5EQmIdj5NhhSJqJZPCmWsKbx100TH1UwaEnhNl0DSaFj51n3bVRrK6Nxce10GWZ HsS1/a63lq/YZLkwfUEvgin/PU9Jx5jMmqhlp3bZjG+f1ItdzJF+9IgS248vCIi2 ystzWCH88Kh69UFcYFfCjeZe8H45XcP+Zykd8WC0DvF/a7Hwk5KTKE/ciT6RPRxb rkWW5EwjqZL9w9cU3rUHWtSVenayQMMEmCfksadr1AExyCrhPqfs9RINyBs2lK5a q2bdSFbXZsNzSyL+3yQAfChvRo1/2FdlFVQy+oVUCActV7L77Y7y6jl+b2qzFsSu xMKwvC/1vDXTvOnGk6A/qJu7yrHpqJrvw1eI+wnMswNBl7lCTgyyHnr5y8S092jI KU4hmSxsYP+y13HmKy4ewPy9DYJYBTSdReKfEFo79Dx8eqySAWjHFL/OPRqhCUYS kBq0eZpVZO7tJnHRaRz8n93wIYzb1UOhhgVwxdjPZF9L4d/jzh1BCv0OBWv8IXCu uWLAi92lL24= =0r9S -----END PGP SIGNATURE----- Merge tag 'soc-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull ARM SoC specific changes from Arnd Bergmann: "These changes are all to SoC-specific code, a total of 33 branches on 17 platforms were pulled into this.
