Subject: [PATCH v2 3/4] arm64: dts: amlogic: meson-s4: add internal SARADC controller
Date: Mon, 23 Mar 2026 09:34:07 +0800	[thread overview]
Message-ID: <20260323013408.429701-4-nick@khadas.com> (raw)
In-Reply-To: <20260323013408.429701-1-nick@khadas.com>

Add the SARADC (Successive Approximation Register ADC) controller
node to the Meson S4 SoC dtsi.

It uses the S4-specific compatible string with a fallback to the
G12A generation, as there are no known hardware differences.
