Subject: [PATCH 3/5] arm: dts: vexpress: Drop unused properties from motherboard node
Date: Thu, 19 Aug 2021 13:42:37 -0500	[thread overview]
Message-ID: <20210819184239.1192395-4-robh@kernel.org> (raw)
In-Reply-To: <20210819184239.1192395-1-robh@kernel.org>

Drop the '#interrupt-cells' property in the motherboard node which has no
effect as the node is neither an interrupt-controller or interrupt-map
(that's in the parent node).

Drop 'model' as it is not used by software nor documented.

Drop 'arm,v2m-memory-map' as it is not used by software. The purpose was
to describe which memory map, but that's all described by the DT
already.
