[PATCH 2/2] mtd: core: find OF node for every MTD partition

From: Rafał Miłecki
Date: Thu Jul 07 2022 - 12:36:29 EST


From: Rafał Miłecki <rafal@xxxxxxxxxx>

Don't limit this feature to the "nvmem-cells". There are more cases to
this.
1. Dynamic partitions may need to be handled with parsers
This applies to "fixed-partitions" parser and all custom ones.
2. Dynamic partitions can be handled with specific drivers
Consider "u-boot,env" as specified in the u-boot,env.yaml.
