<confused> Where did the SATA phy drivers use to live?

$ find -name phy
./drivers/usb/phy
./drivers/phy
./drivers/net/wireless/broadcom/brcm80211/brcmsmac/phy
./drivers/net/phy
./drivers/gpu/drm/msm/dsi/phy
./include/linux/phy
./include/dt-bindings/phy
./Documentation/devicetree/bindings/phy
./Documentation/phy

drivers/ata/ahci.h mentions SATA phy registers.
Is AHCI standardized to the point that platform-specific PHYs
are not required?

Regards.
