Subject: [PATCH 1/2] nvmem: core: support passing DT node in cell info
Date: Mon, 28 Feb 2022 10:33:50 +0100	[thread overview]
Message-ID: <20220228093351.28162-1-zajec5@gmail.com> (raw)

From: Rafał Miłecki <rafal@milecki.pl>

Some hardware may have NVMEM cells described in Device Tree using
individual nodes. Let drivers pass such nodes to the NVMEM subsystem so
they can be later used by NVMEM consumers.
