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 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.
