+    Reguired properities:
+    - compatible : compatible list, contains 2 entries,
+      first is "fsl,CHIP-msi", where CHIP is the processor(mpc8610, mpc8572,
+      etc.) and the second is "fsl,mpic-msi" or "fsl,ipic-msi" depending on
+      the parent type.
+    - reg : should contain the address and the length of the shared message
+      interrupt register set.
+    - msi-available-ranges: use <start count> style section to define which
+      msi interrupt can be used in the 256 msi interrupts. This property is
+      optional, without this, all the 256 MSI interrupts can be used.
+    - interrupts : each one of the interrupts here is one entry per 32 MSIs,
+      and routed to the host interrupt controller. the interrupts should
+      be set as edge sensitive.
+    - interrupt-parent: the phandle for the interrupt controller
+      that services interrupts for this device. for 83xx cpu, the interrupts
+      are routed to IPIC, and for 85xx/86xx cpu the interrupts are routed
+      to MPIC.
+
+    Example
+	msi@41600 {
+		compatible = "fsl,mpc8610-msi", "fsl,mpic-msi";
+		reg = <0x41600 0x80>;
+		msi-available-ranges = <0 0x100>;
+		interrupts = <

+			0xe1 0
+			0xe2 0
+			0xe3 0
+			0xe4 0
+			0xe5 0
+			0xe6 0
+			0xe7 0>;
