Subject: [PATCH v7 1/3] mtd: core: add nvmem-cells compatible to parse mtd as nvmem cells
Date: Fri, 12 Mar 2021 07:28:19 +0100	[thread overview]
Message-ID: <20210312062830.20548-1-ansuelsmth@gmail.com> (raw)

Partitions that contains the nvmem-cells compatible will register
their direct subonodes as nvmem cells and the node will be treated as a
nvmem provider.
