Subject: [PATCH 1/6] nvmem: core: add nvmem_dev_size() helper
Date: Tue, 10 Jan 2023 11:54:20 +0100	[thread overview]
Message-ID: <20230110105425.13188-1-zajec5@gmail.com> (raw)

From: Rafał Miłecki <rafal@milecki.pl>

This is required by layouts that need to read whole NVMEM space. It
applies to NVMEM devices without hardcoded layout (like U-Boot
environment data block).
