Merge tag 'usb-3.10-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb
Pull USB patches from Greg Kroah-Hartman: "Here's the big USB pull request for 3.10-rc1. Lots of USB patches here, the majority being USB gadget changes and USB-serial driver cleanups, the rest being ARM build fixes / cleanups, and individual driver updates. We also finally got some chipidea fixes, which have been delayed for a number of kernel releases, as the maintainer has now reappeared. All of these have been in linux-next for a while" * tag 'usb-3.10-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb: (568 commits) USB: ehci-msm: USB_MSM_OTG needs USB_PHY USB: OHCI: avoid conflicting platform drivers USB: OMAP: ISP1301 needs USB_PHY USB: lpc32xx: ISP1301 needs USB_PHY USB: ftdi_sio: enable two UART ports on ST Microconnect Lite usb: phy: tegra: don't call into tegra-ehci directly usb: phy: phy core cannot yet be a module USB: Fix initconst in ehci driver usb-storage: CY7C68300A chips do not support Cypress ATACB USB: serial: option: Added support Olivetti Olicard 145 USB: ftdi_sio: correct ST Micro Connect Lite PIDs ARM: mxs_defconfig: add CONFIG_USB_PHY ARM: imx_v6_v7_defconfig: add CONFIG_USB_PHY usb: phy: remove exported function from __init section usb: gadget: zero: put function instances on unbind usb: gadget: f_sourcesink.c: correct a copy-paste misnomer usb: gadget: cdc2: fix error return code in cdc_do_config() usb: gadget: multi: fix error return code in rndis_do_config() usb: gadget: f_obex: fix error return code in obex_bind() USB: storage: convert to use module_usb_driver() ...

+USB NOP PHY
+
+Required properties:
+- compatible: should be usb-nop-xceiv
+
+Optional properties:
+- clocks: phandle to the PHY clock. Use as per Documentation/devicetree
+ /bindings/clock/clock-bindings.txt
+ This property is required if clock-frequency is specified.
+
+- clock-names: Should be "main_clk"
+
+- clock-frequency: the clock frequency (in Hz) that the PHY clock must
+ be configured to.
+
+- vcc-supply: phandle to the regulator that provides RESET to the PHY.
+
+- reset-supply: phandle to the regulator that provides power to the PHY.
+
+Example:
+
+ hsusb1_phy {
+ compatible = "usb-nop-xceiv";
+ clock-frequency = <19200000>;
+ clocks = <&osc 0>;
+ clock-names = "main_clk";
+ vcc-supply = <&hsusb1_vcc_regulator>;
+ reset-supply = <&hsusb1_reset_regulator>;
+ };
+
+hsusb1_phy is a NOP USB PHY device that gets its clock from an oscillator
+and expects that clock to be configured to 19.2MHz by the NOP PHY driver.
+hsusb1_vcc_regulator provides power to the PHY and hsusb1_reset_regulator
+controls RESET.
