 This binding describes a SATA device.
 
 Required properties:
- - compatible      : Must be "st,sti-ahci"
+ - compatible      : Must be "st,ahci"
  - reg             : Physical base addresses and length of register sets
  - interrupts      : Interrupt associated with the SATA device
  - interrupt-names :   Associated name must be; "hostc"
- - resets          : The power-down and soft-reset lines of SATA IP
- - reset-names     :   Associated names must be; "pwr-dwn" and "sw-rst"
  - clocks          : The phandle for the clock
  - clock-names     :   Associated name must be; "ahci_clk"
  - phys            : The phandle for the PHY port
  - phy-names       :   Associated name must be; "ahci_phy"
