From 4a575865c1ea67018d96acda9b43e5d3d25b2366 Mon Sep 17 00:00:00 2001 From: Rafał Miłecki Date: Fri, 16 Sep 2022 13:20:49 +0100 Subject: mtd: allow getting MTD device associated with a specific DT node MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit MTD subsystem API allows interacting with MTD devices (e.g. reading, writing, handling bad blocks). So far a random driver could get MTD device only by its name (get_mtd_device_nm()). This change allows getting them also by a DT node. This API is required for drivers handling DT defined MTD partitions in a specific way (e.g. U-Boot (sub)partition with environment variables).
