Subject: [PATCH V2 2/5] nvmem: core: add nvmem_dev_size() helper
Date: Tue, 19 Dec 2023 18:40:22 +0100	[thread overview]
Message-ID: <20231219174025.15228-2-zajec5@gmail.com> (raw)
In-Reply-To: <20231219174025.15228-1-zajec5@gmail.com>

From: Rafał Miłecki <rafal@milecki.pl>

This is required by layouts that need to read whole NVMEM content. It's
especially useful for NVMEM devices without hardcoded layout (like
U-Boot environment data block).
