Merge branch 'next' of git://git.kernel.org/pub/scm/linux/kernel/git/benh/powerpc

Pull powerpc update from Benjamin Herrenschmidt:
 "The main highlight is probably some base POWER8 support.  There's more
  to come such as transactional memory support but that will wait for
  the next one.

  Overall it's pretty quiet, or rather I've been pretty poor at picking
  things up from patchwork and reviewing them this time around and Kumar
  no better on the FSL side it seems..."

+* Freescale 85xx RAID Engine nodes
+
+RAID Engine nodes are defined to describe on-chip RAID accelerators.  Each RAID
+Engine should have a separate node.
+
+Supported chips:
+P5020, P5040
+
+Required properties:
+
+- compatible:	Should contain "fsl,raideng-v1.0" as the value
+		This identifies RAID Engine block. 1 in 1.0 represents
+		major number whereas 0 represents minor number. The
+		version matches the hardware IP version.
+- reg:		offset and length of the register set for the device
+- ranges:	standard ranges property specifying the translation
+		between child address space and parent address space
+
+Example:
+	/* P5020 */
+	raideng: raideng@320000 {
+		compatible = "fsl,raideng-v1.0";
+		#address-cells = <1>;
+		#size-cells = <1>;
+		reg	= <0x320000 0x10000>;
+		ranges	= <0 0x320000 0x10000>;
+	};
+
+
+There must be a sub-node for each job queue present in RAID Engine
+This node must be a sub-node of the main RAID Engine node
+
+- compatible:	Should contain "fsl,raideng-v1.0-job-queue" as the value
+		This identifies the job queue interface
+- reg:		offset and length of the register set for job queue
+- ranges:	standard ranges property specifying the translation
+		between child address space and parent address space
+
+Example:
+	/* P5020 */
+	raideng_jq0@1000 {
+		compatible = "fsl,raideng-v1.0-job-queue";
+		reg	   = <0x1000 0x1000>;
+		ranges	   = <0x0 0x1000 0x1000>;
+	};
+
+
+There must be a sub-node for each job ring present in RAID Engine
+This node must be a sub-node of job queue node
+
+- compatible:	Must contain "fsl,raideng-v1.0-job-ring" as the value
+		This identifies job ring. Should contain either
+		"fsl,raideng-v1.0-hp-ring" or "fsl,raideng-v1.0-lp-ring"
+		depending upon whether ring has high or low priority
+- reg:		offset and length of the register set for job ring
+- interrupts:	interrupt mapping for job ring IRQ
+
+Optional property:
+
+- fsl,liodn:	Specifies the LIODN to be used for Job Ring. This
+		property is normally set by firmware. Value
+		is of 12-bits which is the LIODN number for this JR.
+		This property is used by the IOMMU (PAMU) to distinquish
+		transactions from this JR and than be able to do address
+		translation & protection accordingly.
+
+Example:
+	/* P5020 */
+	raideng_jq0@1000 {
+		compatible = "fsl,raideng-v1.0-job-queue";
+		reg	   = <0x1000 0x1000>;
+		ranges	   = <0x0 0x1000 0x1000>;
+
+		raideng_jr0: jr@0 {
+			compatible = "fsl,raideng-v1.0-job-ring", "fsl,raideng-v1.0-hp-ring";
+			reg	   = <0x0 0x400>;
+			interrupts = <139 2 0 0>;
+			interrupt-parent = <&mpic>;
+			fsl,liodn = <0x41>;
+		};
+	};
