[v2,00/35] mtd: spi-nor: Handle ID collisions and clean params init

Message

Tudor Ambarus July 27, 2021, 4:51 a.m. UTC

Handle flash ID collisions. Clean spi_nor_scan() and the flash
parameters initialization. Add guideliness on how to submit a new
flash proposal. An overview of the patch set can be seen in the
documentation patch, the last in the series.
Documentation/driver-api/mtd/spi-nor.rst is obsolete and must be
updated, but the series is getting big, and I though submitting
what I have to speed the review process. Will handle the documentation
afterwards.

Tested with sst26vf064b, w25q256jvm, is25lp256, s25fl256s0, gd25q256,
n25q256a and mx25l25635e.

Changes in v2: address Pratyush's comments on initial patch set.
