a7726350e0 ARM: arm-soc cleanup for 3.10
Here is a collection of cleanup patches. Among the pieces that stand out are:
 
 - The deletion of h720x platforms
 - Split of at91 non-dt platforms to their own Kconfig file to keep them separate
 - General cleanups and refactoring of i.MX and MXS platforms
 - Some restructuring of clock tables for OMAP
 - Convertion of PMC driver for Tegra to dt-only
 - Some renames of sunxi -> sun4i (Allwinner A10)
 - ... plus a bunch of other stuff that I haven't mentioned

Pull SMP/hotplug changes from Ingo Molnar:
 "This is a pretty large, multi-arch series unifying and generalizing
  the various disjunct pieces of idle routines that architectures have
  historically copied from each other and have grown in random, wildly
  inconsistent and sometimes buggy directions:

   101 files changed, 455 insertions(+), 1328 deletions(-)

  this went through a number of review and test iterations before it was
  committed, it was tested on various architectures, was exposed to
  linux-next for quite some time - nevertheless it might cause problems
  on architectures that don't read the mailing lists and don't regularly
  test linux-next.

  This cat herding excercise was motivated by the -rt kernel, and was
  brought to you by Thomas "the Whip" Gleixner."

64dc9e2e73 usb: patches for v3.10 merge window
Here is the big Gadget & PHY pull request. Many of us have
 been really busy lately getting multiple drivers to a better
 position.
 
 Since this pull request is so large, I will divide it in sections
 so it's easier to grasp what's included.
 
 - cleanups:
 	. UDC drivers no longer touch gadget->dev, that's now udc-core
 		responsibility
 	. Many more UDC drivers converted to usb_gadget_map/unmap_request()
 	. UDC drivers no longer initialize DMA-related fields from gadget's
 		device structure
 	. UDC drivers don't touch gadget.dev.driver directly
 	. UDC drivers don't assign gadget.dev.release directly
 	. Removal of some unused DMA_ADDR_INVALID
 	. Introduction of CONFIG_USB_PHY
 	. All phy drivers have been moved to drivers/usb/phy and renamed to
 		a common naming scheme
 	. Fix PHY layer so it never returns a NULL pointer, also fix all
 		callers to avoid using IS_ERR_OR_NULL()
 	. Sparse fixes all over the place
 	. drivers/usb/otg/ has been deleted
 	. Marvel drivers (mv_udc, ehci-mv, mv_otg and mv_u3d) improved clock
 		usage
 
 - new features:
 	. UDC core now provides a generic way for tracking and reporting
 		UDC's state (not attached, resuming, suspended, addressed,
 		default, etc)
 	. twl4030-usb learned that it shouldn't be enabled during init
 	. Full DT support for DWC3 has been implemented

usb: patches for v3.10 merge window

Here is the big Gadget & PHY pull request. Many of us have
been really busy lately getting multiple drivers to a better
position.

Since this pull request is so large, I will divide it in sections
so it's easier to grasp what's included.

- cleanups:
	. UDC drivers no longer touch gadget->dev, that's now udc-core
		responsibility
	. Many more UDC drivers converted to usb_gadget_map/unmap_request()
	. UDC drivers no longer initialize DMA-related fields from gadget's
		device structure
	. UDC drivers don't touch gadget.dev.driver directly
	. UDC drivers don't assign gadget.dev.release directly
	. Removal of some unused DMA_ADDR_INVALID
	. Introduction of CONFIG_USB_PHY
	. All phy drivers have been moved to drivers/usb/phy and renamed to
		a common naming scheme
	. Fix PHY layer so it never returns a NULL pointer, also fix all
		callers to avoid using IS_ERR_OR_NULL()
	. Sparse fixes all over the place
	. drivers/usb/otg/ has been deleted
	. Marvel drivers (mv_udc, ehci-mv, mv_otg and mv_u3d) improved clock
		usage

- new features:
	. UDC core now provides a generic way for tracking and reporting
		UDC's state (not attached, resuming, suspended, addressed,
		default, etc)
	. twl4030-usb learned that it shouldn't be enabled during init
	. Full DT support for DWC3 has been implemented
	. ab8500-usb learned about pinctrl framework
	. nop PHY learned about DeviceTree and regulators
	. DWC3 learned about suspend/resume
	. DWC3 can now be compiled in host-only and gadget-only (as well as
		DRD) configurations
	. UVC now enables streaming endpoint based on negotiated speed
	. isp1301 now implements the PHY API properly
	. configfs-based interface for gadget drivers which will lead to
		the removal of all code which just combines functions together
		to build functional gadget drivers.
	. f_serial and f_obex were converted to new configfs interface while
		maintaining old interface around.

Later in the series the shmobile_scu_base variable will be
made into a global variable so this is preparation only.

aa8d3bb177 ARM: shmobile: Kill off sh73a0 scu_base_addr() function
Replace scu_base_addr() with a static shmobile_scu_base
variable and introduce SH73A0_SCU_BASE.

Later in the series the shmobile_scu_base variable will be
made into a global variable so this is preparation only.

10e8d4f6dd ARM: mach-shmobile: r8a7779: Minimal setup using DT
Allow a minimal setup of the r8a7779 SoC using a flattened device tree.
In particular, configure the i2c and ethernet controllers using a
flattened device tree.

SCI serial controller and TMU clock source, whose drivers do not yet
support configuration using a flattened device tree, are still configured
using C code in order to allow booting of a board with this SoC.

The ethernet controller also requires a regulator which is a board property.
A sample snippet DT for the marzen board is as follows:

/dts-v1/;
/include/ "r8a7779.dtsi"

/ {
	fixedregulator3v3: fixedregulator@0 {
		compatible = "regulator-fixed";
		regulator-name = "fixed-3.3V";
		regulator-min-microvolt = <3300000>;
		regulator-max-microvolt = <3300000>;
		regulator-boot-on;
		regulator-always-on;
	};
};

&lan0 {
	vddvario-supply = <&fixedregulator3v3>;
	vdd33a-supply = <&fixedregulator3v3>;
};
