+5) Freescale IPIC Interrupt Controllers
+---------------------------------------

+IPIC interrupt controllers are specific to Freescale 83xx
+SOCs. Two cells are required to encode interrupt information.
+The first cell defines the interrupt number. The second cell
+defines the sense and level information.
+
+Sense and level information follows the Linux convention
+(specified in include/linux/interrupt.h) and should be encoded
+as follows:
+
+ 1 = low to high edge sensitive type enabled
the IPIC doesn't support this sense type.
+ 2 = high to low edge sensitive type enabled
+ 4 = active high level sensitive type enabled
nor this.
i.e, sense types 1 and 4 should not be documented in an IPIC context.
