You haven't CC'ed the correct list, therefore it's unlikely this
will get a proper review/getting merged at all.

As Krzysztof already pointed out on another series of yours, please
read submitting-patches.rst.

For nor flash related submissions please also read:
https://docs.kernel.org/driver-api/mtd/spi-nor.html

Wrong indentation?. Please use checkpatch.pl.

drop the name.

This is also autodetected. Drop it.

> +                .no_sfdp_flags = SECT_4K,

No "no_sfdp_flags" for SFDP capable flashes. Drop it.

Doesn't the flash have proper a 4BAIT table?
