Subject: [RFT v4 6/8] ARM: dts: exynos: Remove MCT subnode for interrupt map on Exynos5250
Date: Mon, 23 Sep 2019 18:14:09 +0200	[thread overview]
Message-ID: <20190923161411.9236-6-krzk@kernel.org> (raw)
In-Reply-To: <20190923161411.9236-1-krzk@kernel.org>

Multi Core Timer node has interrupts routed to two different parents -
GIC and combiner.  This was modeled with a interrupt-map within a
subnode but can be expressed in an easier and more common way, directly
in the node itself.

Signed-off-by: Krzysztof Kozlowski <krzk@kernel.org>

Not tested.

Changes since v3:
1. Use interrupts-extended instead of interrupts-map.
