PHY devices are dedicated hardware that handle the physical 12 layer of the protocols in the OSI model. 13 PHYs are commonly used for high speed interfaces such as Serial-ATA 14 or PCI express. 15 The API provides functions to initialize/deinitialize the 16 PHY, power on/off the PHY, and reset the PHY. It's meant to be as 17 compatible as possible with the equivalent framework found in the 18 linux kernel. 19 20config SPL_PHY 21 bool "PHY Core in SPL" 22 depends on DM 23 help 24 PHY support in SPL. 25 26 This framework is designed to provide a generic interface for PHY 27 devices.
