Currently the compatible “qcom,nandcs” is being used for each connected NAND device to support for multiple NAND devices in the same bus. The same thing can be achieved by looking reg property for each sub nodes which contains the chip select number so this patch removes the use of “qcom,nandcs” for specifying NAND device sub nodes. Since there is no user for this driver currently in so changing compatible string is safe. Signed-off-by: Abhishek Sahu <redacted>
Applied to nand/next. Thanks, Boris
