Subject: [PATCH v2] mtd: nand: Add help text for i.MX NAND controllers
Date: Thu, 27 May 2021 01:37:41 -0700
Message-ID: <20210527083741.789109-1-tpiepho@gmail.com> (raw)
There are two different NAND drivers, used for different chips in the
i.MX range. It's quite confusing as to which to use. Add some help
text to clarify.
