+ * Freescale 8xxx/3.0 Gb/s SATA nodes
+
+ SATA nodes are defined to describe on-chip Serial ATA controllers.
+ Each SATA port should have its own node.
+
+ Required properties:
+ - compatible : compatible list, contains 2 entries, first is
+ "fsl,CHIP-sata", where CHIP is the processor
+ (mpc8315, mpc8379, etc.) and the second is
+ "fsl,pq-sata"
+ - interrupts : <interrupt mapping for SATA IRQ>
+ - cell-index : controller index.
+ 1 for controller @ 0x18000
+ 2 for controller @ 0x19000
+ 3 for controller @ 0x1a000
+ 4 for controller @ 0x1b000
+
+ Optional properties:
+ - interrupt-parent : optional, if needed for interrupt mapping
+ - reg : <registers mapping>
+
+ Example:
+
+ sata@18000 {
+ compatible = "fsl,mpc8379-sata", "fsl,pq-sata";
+ reg = <0x18000 0x1000>;
+ cell-index = <1>;
+ interrupts = <2c 8>;
+ interrupt-parent = < &ipic >;
+ };
More devices will be defined as this spec matures.
