Thanks for doing that. I'll review the patches, but I already have a
extra request: can you convert this driver to ->exec_op()? It does not
necessarily have to be done in this patchset, but, that'd be great to
have one more driver converted to the new interface.

BTW, there seems to be a nand_gpio driver, maybe we should merge
ams-delta code into nand_gpio after it's been patched to use the GPIO
consumer API.
