menu "PHY Subsystem" config PHY bool "PHY Core" depends on DM help PHY support. This framework is designed to provide a generic interface for PHY devices. PHY devices are dedicated hardware that handle the physical layer of the protocols in the OSI model. PHYs are commonly used for high speed interfaces such as Serial-ATA or PCI express. The API provides functions to initialize/deinitialize the PHY, power on/off the PHY, and reset the PHY. It's meant to be as compatible as possible with the equivalent framework found in the linux kernel. config SPL_PHY bool "PHY Core in SPL" depends on DM help PHY support in SPL. This framework is designed to provide a generic interface for PHY devices. PHY devices are dedicated hardware that handle the physical layer of the protocols (https://en.wikipedia.org/wiki/OSI_model). PHYs are commonly used for high speed interfaces such as Serial-ATA or PCI express. The API provides functions to initialize/deinitialize the PHY, power on/off the PHY, and reset the PHY. It's meant to be as compatible as possible with the equivalent framework found in the linux kernel. config PHY_SANDBOX bool "Sandbox PHY support" depends on SANDBOX depends on PHY help This select a dummy sandbox PHY driver. It used only to implement the unit tests for the phy framework config NOP_PHY bool "NOP PHY driver" depends on PHY help Support for a no-op PHY driver (stubbed PHY driver). This is useful when a driver uses the PHY framework but no real PHY hardware exists. config SPL_NOP_PHY bool "NOP PHY driver in SPL" depends on SPL_PHY help Support for a no-op PHY driver (stubbed PHY driver) in the SPL. This is useful when a driver uses the PHY framework but no real PHY hardware exists. config BCM6318_USBH_PHY bool "BCM6318 USBH PHY support" depends on PHY && ARCH_BMIPS select POWER_DOMAIN help Support for the Broadcom MIPS BCM6318 USBH PHY. config BCM6348_USBH_PHY bool "BCM6348 USBH PHY support" depends on PHY && ARCH_BMIPS help Support for the Broadcom MIPS BCM6348 USBH PHY. config BCM6358_USBH_PHY bool "BCM6358 USBH PHY support" depends on PHY && ARCH_BMIPS help Support for the Broadcom MIPS BCM6358 USBH PHY. config BCM6368_USBH_PHY bool "BCM6368 USBH PHY support" depends on PHY && ARCH_BMIPS help Support for the Broadcom MIPS BCM6368 USBH PHY. config PIPE3_PHY bool "Support omap's PIPE3 PHY" depends on PHY && ARCH_OMAP2PLUS help Support for the omap PIPE3 phy for sata This PHY is found on omap devices supporting SATA such as dra7, am57x and omap5 config SPL_PIPE3_PHY bool "Support omap's PIPE3 PHY in SPL" depends on SPL_PHY && ARCH_OMAP2PLUS help Support for the omap PIPE3 phy for sata in SPL This PHY is found on omap devices supporting SATA such as dra7, am57x and omap5 config STI_USB_PHY bool "STMicroelectronics USB2 picoPHY driver for STiH407 family" depends on PHY && ARCH_STI help This is the generic phy driver for the picoPHY ports used by USB2 and USB3 Host controllers available on STiH407 SoC families. config PHY_RCAR_GEN2 tristate "Renesas R-Car Gen2 USB PHY" depends on PHY && RCAR_GEN2 help Support for the Renesas R-Car Gen2 USB PHY. This driver operates the PHY connected to USBHS module, PCI EHCI module and USB3.0 module and allows configuring the module multiplexing. config PHY_STM32_USBPHYC tristate "STMicroelectronics STM32 SoC USB HS PHY driver" depends on PHY && ARCH_STM32MP help Enable this to support the High-Speed USB transceiver that is part of STMicroelectronics STM32 SoCs. This driver controls the entire USB PHY block: the USB PHY controller (USBPHYC) and the two 8-bit wide UTMI+ interface. First interface is used by an HS USB Host controller, and the second one is shared between an HS USB OTG controller and an HS USB Host controller, selected by an USB switch. config MESON_GXL_USB_PHY bool "Amlogic Meson GXL USB PHYs" depends on PHY && ARCH_MESON && MESON_GXL imply REGMAP help This is the generic phy driver for the Amlogic Meson GXL USB2 and USB3 PHYS. endmenu
