Subject: [PATCH v2 3/5] arm64: dts: exynos8895: Add Multi Core Timer (MCT) node
Date: Wed, 23 Oct 2024 12:17:32 +0300 [thread overview]
Message-ID: <20241023091734.538682-4-ivo.ivanov.ivanov1@gmail.com> (raw)
In-Reply-To: <20241023091734.538682-1-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.
