Subject: [PATCH v3 1/9] dt-bindings: arm/npcm: Add binding for global control registers (GCR)
Date: Fri, 24 Dec 2021 21:09:27 +0100 [thread overview]
Message-ID: <20211224200935.93817-2-j.neuschaefer@gmx.net> (raw)
In-Reply-To: <20211224200935.93817-1-j.neuschaefer@gmx.net>
A nuvoton,*-gcr node is present in nuvoton-common-npcm7xx.dtsi and will
be added to nuvoton-wpcm450.dtsi. It is necessary for the NPCM7xx and
WPCM450 pinctrl drivers, and may later be used to retrieve SoC model and
version information.
This patch adds a binding to describe this node.

v3:
- Make a few changes suggested by Rob Herring
- Change name of mux-controller node to appease the linter
v2:
- https://lore.kernel.org/lkml/20211207210823.1975632-2-j.neuschaefer@gmx.net/
- Rename node in example to syscon@800000
- Add subnode to example
v1:
- https://lore.kernel.org/lkml/20210602120329.2444672-2-j.neuschaefer@gmx.net/
