   1 * Broadcom SATA3 AHCI 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         : should be one or more of
   8                         "brcm,bcm7216-ahci"
   9                         "brcm,bcm7425-ahci"
  10                         "brcm,bcm7445-ahci"
  11                         "brcm,bcm-nsp-ahci"
  12                         "brcm,sata3-ahci"
  13                         "brcm,bcm63138-ahci"
  14 - reg                : register mappings for AHCI and SATA_TOP_CTRL
  15 - reg-names          : "ahci" and "top-ctrl"
  16 - interrupts         : interrupt mapping for SATA IRQ
  17
  18 Optional properties:
  19
  20 - reset: for "brcm,bcm7216-ahci" must be a valid reset phandle
  21   pointing to the RESCAL reset controller provider node.
  22 - reset-names: for "brcm,bcm7216-ahci", must be "rescal".
