• AHCI SATA Controller

SATA nodes are defined to describe on-chip Serial ATA controllers.
Each SATA controller should have its own node.

Required properties:

• compatible : compatible list, contains “calxeda,hb-ahci” or “snps,spear-ahci”
• interrupts :
• reg :

Optional properties:

• calxeda,port-phys: phandle-combophy and lane assignment, which maps each

        SATA port to a combophy and a lane within that
        combophy
  

• dma-coherent : Present if dma operations are coherent

Example:
sata@ffe08000 {
compatible = “calxeda,hb-ahci”;
reg = <0xffe08000 0x1000>;
interrupts = <115>;
calxeda,port-phys = <&combophy5 0 &combophy0 0 &combophy0 1
&combophy0 2 &combophy0 3>;

    };
