   3 This binding describes a SATA device.
   4
   5 Required properties:
   6  - compatible      : Must be "st,ahci"
   7  - reg             : Physical base addresses and length of register sets
   8  - interrupts      : Interrupt associated with the SATA device
   9  - interrupt-names :   Associated name must be; "hostc"
  10  - clocks          : The phandle for the clock
  11  - clock-names     :   Associated name must be; "ahci_clk"
  12  - phys            : The phandle for the PHY port
  13  - phy-names       :   Associated name must be; "ahci_phy"
  14
  15 Optional properties:
  16  - resets          : The power-down, soft-reset and power-reset lines of SATA IP
  17  - reset-names     :   Associated names must be; "pwr-dwn", "sw-rst" and "pwr-rst"
