Subject: [PATCH] dt-bindings: interrupt-controller: arm,gic: Document resets property
Date: Tue, 19 May 2020 10:05:19 +0200	[thread overview]
Message-ID: <20200519080519.28324-1-geert+renesas@glider.be> (raw)

A generic GIC block embedded in an SoC may be connected to an on-SoC
reset controller.  Hence allow the DTS writer to describe this relation,
by documenting the optional presence of a "reset" property.

This gets rid of "make dtbs_check" warnings like:

    arch/arm/boot/dts/r8a7791-porter.dt.yaml: interrupt-controller@f1001000: 'resets' does not match any of the regexes: '^v2m@[0-9a-f]+$', 'pinctrl-[0-9]+'
