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>; | ||
