7title: Calxeda Highbank Combination PHYs binding for SATA
8
9description: |
10  The Calxeda Combination PHYs connect the SoC to the internal fabric
11  and to SATA connectors. The PHYs support multiple protocols (SATA,
12  SGMII, PCIe) and can be assigned to different devices (SATA or XGMAC
13  controller).
14  Programming the PHYs is typically handled by those device drivers,
15  not by a dedicated PHY driver.
