+title: FSL/NXP Integrated Flash Controller
+

+
+description: |
+ NXP's integrated flash controller (IFC) is an advanced version of the
+ enhanced local bus controller which includes similar programming and signal
+ interfaces with an extended feature set. The IFC provides access to multiple
+ external memory types, such as NAND flash (SLC and MLC), NOR flash, EPROM,
+ SRAM and other memories where address and data are shared on a bus.
+
+properties:
+ $nodename:
+ pattern: "^memory-controller@[0-9a-f]+$"
+
+ compatible:
+ const: fsl,ifc
+
+ "#address-cells":
+ enum: [2, 3]
+ description: |
+ Should be either two or three. The first cell is the chipselect
+ number, and the remaining cells are the offset into the chipselect.
+
+ "#size-cells":
+ enum: [1, 2]
+ description: |
+ Either one or two, depending on how large each chipselect can be.
+
+ reg:
+ maxItems: 1
+
+ interrupts:
+ minItems: 1
+ maxItems: 2
+ description: |
+ IFC may have one or two interrupts. If two interrupt specifiers are
+ present, the first is the "common" interrupt (CM_EVTER_STAT), and the
+ second is the NAND interrupt (NAND_EVTER_STAT). If there is only one,
+ that interrupt reports both types of event.
+
+ little-endian:
+ type: boolean
+ description: |
+ If this property is absent, the big-endian mode will be in use as default
+ for registers.
+
+ ranges:
+ description: |
+ Each range corresponds to a single chipselect, and covers the entire
+ access window as configured.
+
+patternProperties:
+ "^.*@[a-f0-9]+(,[a-f0-9]+)+$":
+ type: object
+ description: |
+ Child device nodes describe the devices connected to IFC such as NOR (e.g.
+ cfi-flash) and NAND (fsl,ifc-nand). There might be board specific devices
+ like FPGAs, CPLDs, etc.
