   1 FLCTL NAND controller
   2
   3 Required properties:
   4 - compatible : "renesas,shmobile-flctl-sh7372"
   5 - reg : Address range of the FLCTL
   6 - interrupts : flste IRQ number
   7 - nand-bus-width : bus width to NAND chip
   8
   9 Optional properties:
  10 - dmas: DMA specifier(s)
  11 - dma-names: name for each DMA specifier. Valid names are
  12              "data_tx", "data_rx", "ecc_tx", "ecc_rx"
  13
  14 The DMA fields are not used yet in the driver but are listed here for
  15 completing the bindings.
  16
  17 The device tree may optionally contain sub-nodes describing partitions of the
  18 address space. See partition.txt for more detail.
