Subject: [PATCH 1/2] arm: dts: sunplus: add peripheral device nodes to sp7021.dtsi
Date: Wed,  2 Sep 2026 12:45:44 +0200	[thread overview]
Message-ID: <20260902104545.67794-2-ag@ffroot.co.za> (raw)
In-Reply-To: <20260902104545.67794-1-ag@ffroot.co.za>

Add device tree nodes for SP7021 peripherals whose drivers are already
upstream:

- PWM controller
- Watchdog/STC timer
- eMMC controller (mmc0)
- Ethernet switch (L2SW)
