13description:
14  The Macronix Multi-Interface Raw NAND Controller is a versatile flash
15  memory controller for embedding in SoCs, capable of interfacing with
16  various NAND devices. It requires dedicated clock inputs for core, data
17  transmit, and delayed transmit paths along with register space and an
18  interrupt line for operation.
