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 PIPE3_PHY bool "Support omap's PIPE3 PHY" depends on PHY && ARCH_OMAP2 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_OMAP2 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 endmenu
