Subject: [PATCH 2/9] dt-bindings: ata: Convert fsl,pq-sata binding to YAML

From: "J. Neuschäfer" <j.ne@...teo.net>

Convert the Freescale PowerQUICC SATA controller binding from text form
to YAML. The list of compatible strings reflects current usage.

-* 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:
-- reg               : <registers mapping>
-
-Example:
-	sata@...00 {
-		compatible = "fsl,mpc8379-sata", "fsl,pq-sata";
-		reg = <0x18000 0x1000>;
-		cell-index = <1>;
-		interrupts = <2c 8>;
-		interrupt-parent = < &ipic >;
-	};
