This transceiver supports high and full speed devices plus,	  in host mode, low speed. config FSL_USB2_OTG	tristate "Freescale USB OTG Transceiver Driver"	depends on USB_EHCI_FSL && USB_FSL_USB2 && USB_OTG_FSM=y && PM	depends on USB_GADGET || !USB_GADGET # if USB_GADGET=m, this can't be 'y'	select USB_PHY	help	  Enable this to support Freescale USB OTG transceiver. config KEYSTONE_USB_PHY	tristate "Keystone USB PHY Driver"	depends on ARCH_KEYSTONE || COMPILE_TEST	depends on NOP_USB_XCEIV	help	  Enable this to support Keystone USB phy. This driver provides	  interface to interact with USB 2.0 and USB 3.0 PHY that is part	  of the Keystone SOC. config NOP_USB_XCEIV	tristate "NOP USB Transceiver Driver"	depends on USB_GADGET || !USB_GADGET # if USB_GADGET=m, NOP can't be built-in	select USB_PHY	help	  This driver is to be used by all the usb transceiver which are either	  built-in with usb ip or which are autonomous and doesn't require any	  phy programming such as ISP1x04 etc. config AM335X_CONTROL_USB	tristate config AM335X_PHY_USB	tristate "AM335x USB PHY Driver"	depends on ARM || COMPILE_TEST	depends on NOP_USB_XCEIV	select USB_PHY	select AM335X_CONTROL_USB	select USB_COMMON	help	  This driver provides PHY support for that phy which part for the	  AM335x SoC. config TWL6030_USB	tristate "TWL6030 USB Transceiver Driver"	depends on TWL4030_CORE && OMAP_USB2 && USB_MUSB_OMAP2PLUS	depends on OF	help	  Enable this to support the USB OTG transceiver on TWL6030	  family chips. This TWL6030 transceiver has the VBUS and ID GND	  and OTG SRP events capabilities. For all other transceiver functionality	  UTMI PHY is embedded in OMAP4430. The internal PHY configurations APIs	  are hooked to this driver through platform_data structure.	  The definition of internal PHY APIs are in the mach-omap2 layer. config USB_GPIO_VBUS	tristate "GPIO based peripheral-only VBUS sensing 'transceiver'"	depends on GPIOLIB || COMPILE_TEST	depends on USB_GADGET || !USB_GADGET # if USB_GADGET=m, this can't be 'y'	depends on !USB_CONN_GPIO	select USB_PHY	help	  Provides simple GPIO VBUS sensing for controllers with an	  internal transceiver via the usb_phy interface, and	  optionally control of a D+ pullup GPIO as well as a VBUS	  current limit regulator. This driver is for devices that do	  NOT support role switch. OTG devices that can do role switch	  (master/peripheral) shall use the USB based connection	  detection driver USB_CONN_GPIO. config OMAP_OTG	tristate "OMAP USB OTG controller driver"	depends on ARCH_OMAP_OTG && EXTCON	help	  Enable this to support some transceivers on OMAP1 platforms. OTG	  controller is needed to switch between host and peripheral modes. 	  This driver can also be built as a module. If so, the module	  will be called phy-omap-otg. config TAHVO_USB	tristate "Tahvo USB transceiver driver"	depends on MFD_RETU	depends on USB_GADGET || !USB_GADGET # if USB_GADGET=m, this can't be 'y'	select USB_PHY	help	  Enable this to support USB transceiver on Tahvo. This is used	  at least on Nokia 770. config TAHVO_USB_HOST_BY_DEFAULT	depends on TAHVO_USB	bool "Device in USB host mode by default"	help	  Say Y here, if you want the device to enter USB host mode	  by default on bootup. config USB_ISP1301	tristate "NXP ISP1301 USB transceiver support"	depends on USB || USB_GADGET	depends on I2C	select USB_PHY	help	  Say Y here to add support for the NXP ISP1301 USB transceiver driver.	  This chip is typically used as USB transceiver for USB host, gadget	  and OTG drivers (to be selected separately). 	  To compile this driver as a module, choose M here: the	  module will be called phy-isp1301. config USB_MXS_PHY	tristate "Freescale MXS USB PHY support"	depends on ARCH_MXC || ARCH_MXS	select STMP_DEVICE	select USB_PHY	help	  Enable this to support the Freescale MXS USB PHY. 	  MXS Phy is used by some of the i.MX SoCs, for example imx23/28/6x. config USB_TEGRA_PHY	tristate "NVIDIA Tegra USB PHY Driver"	depends on ARCH_TEGRA || COMPILE_TEST	select USB_COMMON	select USB_PHY	select USB_ULPI	help	  This driver provides PHY support for the USB controllers found	  on NVIDIA Tegra SoC's. config USB_ULPI	bool "Generic ULPI Transceiver Driver"	depends on ARM || ARM64 || COMPILE_TEST	select USB_ULPI_VIEWPORT	help	  Enable this to support ULPI connected USB OTG transceivers which	  are likely found on embedded boards. config USB_ULPI_VIEWPORT	bool	help	  Provides read/write operations to the ULPI phy register set for	  controllers with a viewport register (e.g. Chipidea/ARC controllers). endmenu
