Subject: [RFT v3 5/8] ARM: dts: exynos: Remove MCT subnode for interrupt map on Exynos4412
Date: Sat, 21 Sep 2019 19:01:49 +0200 [thread overview]
Message-ID: <20190921170152.5033-5-krzk@kernel.org> (raw)
In-Reply-To: <20190921170152.5033-1-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.
Tested on Odroid U3 (Exynos4412).
