    1 * APM X-Gene 6.0 Gb/s SATA host controller nodes
    2 
    3 SATA host controller nodes are defined to describe on-chip Serial ATA
    4 controllers. Each SATA controller (pair of ports) have its own node.
    5 
    6 Required properties:
    7 - compatible            : Shall contain:
    8   * "apm,xgene-ahci"
    9 - reg                   : First memory resource shall be the AHCI memory
   10                           resource.
   11                           Second memory resource shall be the host controller
   12                           core memory resource.
   13                           Third memory resource shall be the host controller
   14                           diagnostic memory resource.
   15                           4th memory resource shall be the host controller
   16                           AXI memory resource.
   17                           5th optional memory resource shall be the host
   18                           controller MUX memory resource if required.
   19 - interrupts            : Interrupt-specifier for SATA host controller IRQ.
   20 - clocks                : Reference to the clock entry.
   21 - phys                  : A list of phandles + phy-specifiers, one for each
   22                           entry in phy-names.
   23 - phy-names             : Should contain:
   24   * "sata-phy" for the SATA 6.0Gbps PHY
   25 
   26 Optional properties:
   27 - dma-coherent          : Present if dma operations are coherent
   28 - status                : Shall be "ok" if enabled or "disabled" if disabled.
   29                           Default is "ok".
