Nand device bindings may contain additional sub-nodes describing partitions of
the address space. See partition.txt for more detail. The NAND Flash timing
values must be programmed in the chip select’s node of AEMIF
memory-controller (see Documentation/devicetree/bindings/memory-controllers/
davinci-aemif.txt).
