+* Freescale MSI interrupt controller
+
+Required properties:
+- 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 = <
+ 0xe0 0
+ 0xe1 0
+ 0xe2 0
+ 0xe3 0
+ 0xe4 0
+ 0xe5 0
+ 0xe6 0
+ 0xe7 0>;
+ interrupt-parent = <&mpic>;
+ };
