Subject: [PATCH v1 4/6] arm64: dts: exynos8895: Add Multi Core Timer (MCT) node
Date: Sun, 20 Oct 2024 21:21:19 +0300	[thread overview]
Message-ID: <20241020182121.377969-5-ivo.ivanov.ivanov1@gmail.com> (raw)
In-Reply-To: <20241020182121.377969-1-ivo.ivanov.ivanov1@gmail.com>

MCT has one global timer and 8 CPU local timers. The global timer
can generate 4 interrupts, and each local timer can generate an
interrupt making 12 interrupts in total.
