Subject: [PATCH 1/8] dt-bindings: arm/npcm: Add binding for global control registers (GCR)
Date: Wed,  2 Jun 2021 14:03:22 +0200	[thread overview]
Message-ID: <20210602120329.2444672-2-j.neuschaefer@gmx.net> (raw)
In-Reply-To: <20210602120329.2444672-1-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.

+  The Global Control Registers (GCR) are a block of registers in Nuvoton SoCs
+  that expose misc functionality such as chip model and version information or
+  pinmux settings.
