[PATCH v2 00/23] mtd: rawnand: Stop passing mtd_info to drivers

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hello,

This is the first set of patches aiming at cleaning the raw NAND API.

This one focuses on inconsistencies we have in the API + the nand_chip
and nand_ecc_ctrl interfaces. Some functions/hooks are passed a
nand_chip object, some are passed an mtd_info object and some are
passed both.

Since mtd_info can be extracted from nand_chip, we can simply always
pass a nand_chip and make things consistent. Hopefully with these
changes merged we'll stop seeing new drivers reproducing the same
mistake (passing both mtd_info and nand_chip or using mtd_info where
nand_chip is more appropriate).

For those who want to see what's in the pipe, here is a branch [1]
containing all the cleanups I plan to merge.

Not much has changed in this v2. I just rebased on top of nand/next,
fixed typos, added A-b/R-b tags, and that's all.

Regards,

Boris
