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.

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_RCAR_GEN3
tristate "Renesas R-Car Gen3 USB PHY"
depends on PHY && RCAR_GEN3 && CLK && DM_REGULATOR
default y if RCAR_GEN3
help
Support for the Renesas R-Car Gen3 USB PHY. This driver operates the
PHY connected to EHCI USB module and controls USB OTG operation.
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
