13   NXP's integrated flash controller (IFC) is an advanced version of the
15   interfaces with an extended feature set. The IFC provides access to multiple
16   external memory types, such as NAND flash (SLC and MLC), NOR flash, EPROM,
21     pattern: "^memory-controller@[0-9a-f]+$"
24     const: fsl,ifc
26   "#address-cells":
32   "#size-cells":
44       IFC may have one or two interrupts.  If two interrupt specifiers are
46       second is the NAND interrupt (NAND_EVTER_STAT).  If there is only one,
49   little-endian:
52       If this property is absent, the big-endian mode will be in use as default
61   "^.*@[a-f0-9]+(,[a-f0-9]+)+$":
64       Child device nodes describe the devices connected to IFC such as NOR (e.g.
65       cfi-flash) and NAND (fsl,ifc-nand). There might be board specific devices
