Pull USB patches from Greg Kroah-Hartman: "Here's the big USB merge for 3.9-rc1 Nothing major, lots of gadget fixes, and of course, xhci stuff. All of this has been in linux-next for a while, with the exception of the last 3 patches, which were reverts of patches in the tree that caused problems, they went in yesterday." * tag 'usb-3.9-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb: (190 commits) Revert "USB: EHCI: make ehci-vt8500 a separate driver" Revert "USB: EHCI: make ehci-orion a separate driver" Revert "USB: update host controller Kconfig entries" USB: update host controller Kconfig entries USB: EHCI: make ehci-orion a separate driver USB: EHCI: make ehci-vt8500 a separate driver USB: usb-storage: unusual_devs update for Super TOP SATA bridge USB: ehci-omap: Fix autoloading of module USB: ehci-omap: Don't free gpios that we didn't request USB: option: add Huawei "ACM" devices using protocol = vendor USB: serial: fix null-pointer dereferences on disconnect USB: option: add Yota / Megafon M100-1 4g modem drivers/usb: add missing GENERIC_HARDIRQS dependencies USB: storage: properly handle the endian issues of idProduct testusb: remove all mentions of 'usbfs' usb: gadget: imx_udc: make it depend on BROKEN usb: omap_control_usb: fix compile warning ARM: OMAP: USB: Add phy binding information ARM: OMAP2: MUSB: Specify omap4 has mailbox ARM: OMAP: devices: create device for usb part of control module ...

+* Samsung's usb phy transceiver
+
+The Samsung's phy transceiver is used for controlling usb phy for
+s3c-hsotg as well as ehci-s5p and ohci-exynos usb controllers
+across Samsung SOCs.
+TODO: Adding the PHY binding with controller(s) according to the under
+developement generic PHY driver.
+
+Required properties:
+
+Exynos4210:
+- compatible : should be "samsung,exynos4210-usbphy"
+- reg : base physical address of the phy registers and length of memory mapped
+ region.
+
+Exynos5250:
+- compatible : should be "samsung,exynos5250-usbphy"
+- reg : base physical address of the phy registers and length of memory mapped
+ region.
+
+Optional properties:
+- #address-cells: should be '1' when usbphy node has a child node with 'reg'
+ property.
+- #size-cells: should be '1' when usbphy node has a child node with 'reg'
+ property.
+- ranges: allows valid translation between child's address space and parent's
+ address space.
+
+- The child node 'usbphy-sys' to the node 'usbphy' is for the system controller
+ interface for usb-phy. It should provide the following information required by
+ usb-phy controller to control phy.
+ - reg : base physical address of PHY_CONTROL registers.
+ The size of this register is the total sum of size of all PHY_CONTROL
+ registers that the SoC has. For example, the size will be
+ '0x4' in case we have only one PHY_CONTROL register (e.g.
+ OTHERS register in S3C64XX or USB_PHY_CONTROL register in S5PV210)
+ and, '0x8' in case we have two PHY_CONTROL registers (e.g.
+ USBDEVICE_PHY_CONTROL and USBHOST_PHY_CONTROL registers in exynos4x).
+ and so on.
+
+Example:
+ - Exynos4210
+
+ usbphy@125B0000 {
+ #address-cells = <1>;
+ #size-cells = <1>;
+ compatible = "samsung,exynos4210-usbphy";
+ reg = <0x125B0000 0x100>;
+ ranges;
+
+ usbphy-sys {
+ /* USB device and host PHY_CONTROL registers */
+ reg = <0x10020704 0x8>;
+ };
+ };
