    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.
   19 
   20 Example:
   21 
   22         flctl@e6a30000 {
   23                 #address-cells = <1>;
   24                 #size-cells = <1>;
   25                 compatible = "renesas,shmobile-flctl-sh7372";
   26                 reg = <0xe6a30000 0x100>;
   27                 interrupts = <0x0d80>;
   28 
   29                 nand-bus-width = <16>;
   30 
   31                 dmas = <&dmac 1 /* data_tx */
   32                         &dmac 2;> /* data_rx */
   33                 dma-names = "data_tx", "data_rx";
   34 
   35                 system@0 {
   36                         label = "system";
   37                         reg = <0x0 0x8000000>;
   38                 };
   39 
   40                 userdata@8000000 {
   41                         label = "userdata";
   42                         reg = <0x8000000 0x10000000>;
   43                 };
   44 
   45                 cache@18000000 {
   46                         label = "cache";
   47                         reg = <0x18000000 0x8000000>;
