   3 This binding describes a SATA device.
   4
   5 Required properties:
   6  - compatible      : Must be "st,sti-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  - resets          : The power-down and soft-reset lines of SATA IP
  11  - reset-names     :   Associated names must be; "pwr-dwn" and "sw-rst"
  12  - clocks          : The phandle for the clock
  13  - clock-names     :   Associated name must be; "ahci_clk"
  14  - phys            : The phandle for the PHY device
  15  - phy-names       :   Associated name must be; "ahci_phy"
