   1 * AHCI SATA Controller
   2
   3 SATA nodes are defined to describe on-chip Serial ATA controllers.
   4 Each SATA controller should have its own node.
   5
   6 Required 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
  11 Optional 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 - calxeda,sgpio-gpio: phandle-gpio bank, bit offset, and default on or off,
  16                         which indicates that the driver supports SGPIO
  17                         indicator lights using the indicated GPIOs
  18 - calxeda,led-order : a u32 array that map port numbers to offsets within the
  19                         SGPIO bitstream.
  20 - dma-coherent      : Present if dma operations are coherent
  21
  22 Example:
  23         sata@ffe08000 {
  24                 compatible = "calxeda,hb-ahci";
  25                 reg = <0xffe08000 0x1000>;
  26                 interrupts = <115>;
  27                 calxeda,port-phys = <&combophy5 0 &combophy0 0 &combophy0 1
  28                                         &combophy0 2 &combophy0 3>;
