[PATCH 10/13] nvmem: u-boot-env: find Device Tree nodes for NVMEM cells

From: Srinivas Kandagatla
Date: Fri Sep 16 2022 - 08:21:52 EST


From: Rafał Miłecki <rafal@xxxxxxxxxx>

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.
