Subject: [PATCH v2 2/3] arm64: dts: exynos: axis: Add initial ARTPEC-9 SoC support
Date: Wed, 19 Nov 2025 18:43:01 +0530	[thread overview]
Message-ID: <20251119131302.79088-3-ravi.patel@samsung.com> (raw)
In-Reply-To: <20251119131302.79088-1-ravi.patel@samsung.com>

From: SungMin Park <smn1196@coasia.com>

Add initial device tree support for Axis ARTPEC-9 SoC.

This SoC contains 6 Cortex-A55 CPUs and several other peripheral IPs.
