Subject: [PATCH v6 1/3] dt-bindings: reset: Add syscon to nuvoton ma35d1 system-management node
Date: Wed, 13 Mar 2024 03:57:17 +0000	[thread overview]
Message-ID: <20240313035719.768469-2-ychuang570808@gmail.com> (raw)
In-Reply-To: <20240313035719.768469-1-ychuang570808@gmail.com>

From: Jacky Huang <ychuang3@nuvoton.com>

Add a compatible 'syscon' to the system management node since the system
control registers are mapped by this driver. The other driver must access
the system control registers through 'regmap' using a phandle that
references this node.
