Subject: [PATCH] nvmem: u-boot-env: find Device Tree nodes for NVMEM cells
Date: Thu, 15 Sep 2022 22:06:29 +0200 [thread overview]
Message-ID: <20220915200629.10270-1-zajec5@gmail.com> (raw)
From: Rafał Miłecki <rafal@milecki.pl>
DT binding allows specifying NVMEM cells as NVMEM device (provider)
subnodes. Looks for such subnodes when building NVMEM cells.
This allows NVMEM consumers to use U-Boot environment variables.
