Commit 271707b1 ("mtd: nand: denali: max_banks calculation changed in revision 5.1") added a revision check to support the new max_banks encoding. Its git-log states "The encoding of max_banks changed in Denali revision 5.1". There are exceptional cases, for example, the revision register on some UniPhier SoCs says the IP is 5.0 but the max_banks is encoded in the new format. This IP updates the resister specification from time to time (often breaking the backward compatibility), but the revision number is not incremented correctly. The max_banks is not only the case that needs revision checking. Let's allow to override an incorrect revision number.
