Subject[PATCH v2 2/9] dt-bindings: mtd: ingenic: Add compatible strings for the JZ4740
Add compatible strings to probe the jz4780-nand and jz4780-bch drivers
from devicetree on the JZ4725B and JZ4740 SoCs from Ingenic.

Signed-off-by: Paul Cercueil <>


v2: - Change 'ingenic,jz4725b-nand' compatible string to
'ingenic,jz4740-nand' to reflect driver change
- Add 'ingenic,jz4740-bch' compatible string
- Document 'ingenic,oob-layout' property
