0007 title: Calxeda Highbank Combination PHYs binding for SATA
0008
0009 description: |
0010   The Calxeda Combination PHYs connect the SoC to the internal fabric
0011   and to SATA connectors. The PHYs support multiple protocols (SATA,
0012   SGMII, PCIe) and can be assigned to different devices (SATA or XGMAC
0013   controller).
0014   Programming the PHYs is typically handled by those device drivers,
0015   not by a dedicated PHY driver.
