 - target-supply     : regulator for SATA target power
 - phys              : reference to the SATA PHY node
 - phy-names         : must be "sata-phy"
+- ports-implemented : Mask that indicates which ports that the HBA supports

 Required properties when using sub-nodes:
 - #address-cells    : number of cells to encode an address
