Subject: [PATCH 2/2] nvmem: brcm_nvram: find Device Tree nodes for NVMEM cells
Date: Mon, 28 Feb 2022 10:33:51 +0100	[thread overview]
Message-ID: <20220228093351.28162-2-zajec5@gmail.com> (raw)
In-Reply-To: <20220228093351.28162-1-zajec5@gmail.com>

From: Rafał Miłecki <rafal@milecki.pl>

DT binding for Broadcom's NVRAM supports specifying NVMEM cells as NVMEM
device (provider) subnodes. Look for such subnodes when collecing NVMEM
cells. This allows NVMEM consumers to use NVRAM variables.
