Subject: [PATCH 1/3] mtd: core: call devm_of_platform_populate() for MTD devices
Date: Wed, 22 Dec 2021 20:23:18 +0100	[thread overview]
Message-ID: <20211222192320.21974-1-zajec5@gmail.com> (raw)

From: Rafał Miłecki <rafal@milecki.pl>

This adds support for bindings present in MTD devices (applies to
partitions too) nodes. The purpose of this change is to allow drivers
handle MTD device (partition) data. Some partitions may contain info
that requires parsing & processing.

An example can be U-Boot partition that contains block with environment
variables somehwere in a middle. That block should be described in DT
and parsed by a specific driver.
