1# 2# Physical Layer USB driver configuration 3# 4menuconfig USB_PHY 5 bool "USB Physical Layer drivers" 6 help 7 Most USB controllers have the physical layer signalling part 8 (commonly called a PHY) built in. However, dual-role devices 9 (a.k.a. USB on-the-go) which support being USB master or slave 10 with the same connector often use an external PHY. 11 12 The drivers in this submenu add support for such PHY devices. 13 They are not needed for standard master-only (or the vast 14 majority of slave-only) USB interfaces. 15 16 If you're not sure if this applies to you, it probably doesn't; 17 say N here. 18 19if USB_PHY 20 21# 22# USB Transceiver Drivers 23# 24config AB8500_USB 25 tristate "AB8500 USB Transceiver Driver" 26 depends on AB8500_CORE 27 help 28 Enable this to support the USB OTG transceiver in AB8500 chip. 29 This transceiver supports high and full speed devices plus, 30 in host mode, low speed. 31 32config FSL_USB2_OTG 33 bool "Freescale USB OTG Transceiver Driver" 34 depends on USB_EHCI_FSL && USB_FSL_USB2 && PM_RUNTIME 35 select USB_OTG 36 help 37 Enable this to support Freescale USB OTG transceiver. 38 39config ISP1301_OMAP 40 tristate "Philips ISP1301 with OMAP OTG" 41 depends on I2C && ARCH_OMAP_OTG 42 help 43 If you say yes here you get support for the Philips ISP1301 44 USB-On-The-Go transceiver working with the OMAP OTG controller. 45 The ISP1301 is a full speed USB transceiver which is used in 46 products including H2, H3, and H4 development boards for Texas 47 Instruments OMAP processors. 48 49 This driver can also be built as a module.
