   2
   3 SATA nodes are defined to describe on-chip Serial ATA controllers.
   4 Each SATA controller should have its own node.

   6 Required properties:
   7 - compatible            : compatible list, contains "samsung,exynos5-sata"
   8 - interrupts            : <interrupt mapping for SATA IRQ>
   9 - reg                   : <registers mapping>
  10 - samsung,sata-freq     : <frequency in MHz>
  11 - phys                  : Must contain exactly one entry as specified
  12                           in phy-bindings.txt
  13 - phy-names             : Must be "sata-phy"
  14
  15 Optional properties:
  16 - clocks                : Must contain an entry for each entry in clock-names.
  17 - clock-names           : Shall be "sata" for the external SATA bus clock,
  18                           and "sclk_sata" for the internal controller clock.

  20 Example:
  21         sata@122f0000 {
  22                 compatible = "snps,dwc-ahci";
  23                 samsung,sata-freq = <66>;
  24                 reg = <0x122f0000 0x1ff>;
  25                 interrupts = <0 115 0>;
  26                 clocks = <&clock 277>, <&clock 143>;
  27                 clock-names = "sata", "sclk_sata";
  28                 phys = <&sata_phy>;
  29                 phy-names = "sata-phy";
  30         };
