Subject: [PATCH v1 19/20] arm64: dts: mediatek: mt8192: Add Smart Voltage Scaling node
Date: Fri, 17 Nov 2023 10:42:27 +0100	[thread overview]
Message-ID: <20231117094228.40013-20-angelogioacchino.delregno@collabora.com> (raw)
In-Reply-To: <20231117094228.40013-1-angelogioacchino.delregno@collabora.com>

Add the MediaTek SVS node: this will lower the voltage of various
components of the SoC based on chip quality (read from fuses) in
order to save power and generate less heat.
