[PATCH 2/8] dt-bindings: nvmem: add transformation bindings
From: Michael Walle <hidden>
Date: 2021-12-28 14:26:28
Also in:
linux-devicetree, lkml, netdev
Subsystem:
memory technology devices (mtd), nvmem framework, open firmware and flattened device tree bindings, the rest · Maintainers:
Miquel Raynal, Richard Weinberger, Vignesh Raghavendra, Srinivas Kandagatla, Rob Herring, Krzysztof Kozlowski, Conor Dooley, Linus Torvalds
Just add a simple list of the supported devices which need a nvmem transformations. Also, since the compatible string is prepended to the actual nvmem compatible string, we need to match using "contains" instead of an exact match.
