From: Miquel Raynal Date: Thu, 27 Aug 2020 08:51:53 +0000 (+0200) Subject: dt-bindings: mtd: Document nand-ecc-placement X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=2d76f470224617fadfb35853d7d782b5caa56f9a;p=linux.git dt-bindings: mtd: Document nand-ecc-placement This optional property defines where the ECC bytes are expected to be stored. No value defaults to an unknown location, while these locations can be explicitly set to OOB or interleaved depending if the ECC bytes are entirely stored in the OOB area or mixed with regular data in the main area (also sometimes referred as "syndrome").
