[PATCH v4 1/1] dt-bindings: memory-controllers: fsl,ifc: split child node differences

[PATCH v4 1/1] dt-bindings: memory-controllers: fsl,ifc: split child node differences

[Frank Li]

ifc can connect nor, nand and fpag. Split "^.*@..." into "nand@..." and
"(flash|fpga|board-control|cpld)@..." to better describe the child's node
binding requirements.

Fix below warning:
arch/arm64/boot/dts/freescale/fsl-ls1043a-qds.dtb: /soc/memory-controller@1530000/nand@1,0:
	failed to match any schema with compatible: ['fsl,ifc-nand']

---
Change from v3 to v4
- add pattern property for fpga.
- fine tune commit message.
Change from v2 to v3
- add partition child node for nand
- Only partition property is used at ppc
Change from v1 to v2
- add address-cells and size-cells
