[PATCH v4 1/4] dt-bindings: mtd: raw-nand-chip: Relax node name pattern
From: J. Neuschäfer via B4 Relay
Date: Thu Mar 13 2025 - 17:36:07 EST
From: "J. Neuschäfer" <j.ne@xxxxxxxxxx>
In some scenarios, such as under the Freescale eLBC bus, there are raw
NAND chips with a unit address that has a comma in it (cs,offset).
For reasons of compatibility with historical device trees and
readability of the unit addresses, this format is kept.
Relax the $nodename pattern in raw-nand-chip.yaml to allow such unit
addresses. Unfortunately $nonenames defined in bindings that reference
raw-nand

V4:
- reintroduce patch to silence dtc validation error, after discussion
with Rob Herring and Miquèl Raynal
- add some more detail to the commit message
- remove unit address format rather than extending it
(old pattern: "^nand@[a-f0-9](,[0-9a-f]*)?$")
V3:
- remove patch after discussion with Miquèl Raynal
V2:
- new patch
