   1* AHCI SATA Controller
   2
   3SATA nodes are defined to describe on-chip Serial ATA controllers.
   4Each SATA controller should have its own node.
   5
   6Required properties:
   7- compatible        : compatible list, contains "calxeda,hb-ahci" or "snps,spear-ahci"
   8- interrupts        : <interrupt mapping for SATA IRQ>
   9- reg               : <registers mapping>
  10
  11Optional properties:
  12- calxeda,port-phys: phandle-combophy and lane assignment, which maps each
  13                        SATA port to a combophy and a lane within that
  14                        combophy
  15- dma-coherent      : Present if dma operations are coherent
  16
  17Example:
  18        sata@ffe08000 {
  19                compatible = "calxeda,hb-ahci";
  20                reg = <0xffe08000 0x1000>;
  21                interrupts = <115>;
  22                calxeda,port-phys = <&combophy5 0 &combophy0 0 &combophy0 1
  23                                        &combophy0 2 &combophy0 3>;
  24
  25        };
