1 * Freescale General-Purpose Media Interface (GPMI)
3 The GPMI nand controller provides an interface to control the
4 NAND flash chips. We support only one NAND chip now.
7 - compatible : should be "fsl,<chip>-gpmi-nand"
8 - reg : should contain registers location and length for gpmi and bch.
9 - reg-names: Should contain the reg names "gpmi-nand" and "bch"
10 - interrupts : BCH interrupt number.
11 - interrupt-names : Should be "bch".
12 - dmas: DMA specifier, consisting of a phandle to DMA controller node
13 and GPMI DMA channel ID.
14 Refer to dma.txt and fsl-mxs-dma.txt for details.
15 - dma-names: Must be "rx-tx".
18 - nand-on-flash-bbt: boolean to enable on flash bbt option if not
20 - fsl,use-minimum-ecc: Protect this NAND flash with the minimum ECC
21 strength required. The required ECC strength is
22 automatically discoverable for some flash
23 (e.g., according to the ONFI standard).
24 However, note that if this strength is not
25 discoverable or this property is not enabled,
26 the software may chooses an implementation-defined
29 The device tree may optionally contain sub-nodes describing partitions of the
30 address space. See partition.txt for more detail.
