Subject: [PATCH v9 1/3] dt-bindings: reset: Add syscon to nuvoton ma35d1 system-management node

From: Jacky Huang <ychuang3@...oton.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.
