MTD: pxa3xx-nand: add devicetree bindings This patch contains a hack to get the DMA resources of the device when probed from a devicetree node. This can be removed once a generic DMA controller framework lands. A mtd_part_parser_data is passed mtd_device_parse_register which contains a reference to the device node, so MTD partitions can be added as children.

PXA3xx NAND DT bindings
Required properties:
mtd: nand: pxa3xx: devicetree binding update Since the driver supports the new compatible string, the binding documentation must be updated to reflect it.

- reg: The register base for the controller
- interrupts: The interrupt to map
- #address-cells: Set to <1> if the node includes partitions
Optional properties:
mtd: nand: pxa3xx: add optional dma for pxa architecture The PXA architecture provides a DMA to pump data from the nand controller to memory and the other way around. Add it to the binding description. Signed-off-by: Robert Jarzmik <robert.jarzmik@free.fr> Signed-off-by: Rob Herring <robh@kernel.org>

- nand-ecc-strength: number of bits to correct per ECC step
- nand-ecc-step-size: number of data bytes covered by a single ECC step
The following ECC strength and step size are currently supported:
- nand-ecc-strength = <1>, nand-ecc-step-size = <512>
- nand-ecc-strength = <4>, nand-ecc-step-size = <512>
- nand-ecc-strength = <8>, nand-ecc-step-size = <512>
