Subject: [PATCH v2 2/4] arm64: dts: mediatek: mt8195-cherry: Update min voltage constraint for MT6315
Date: Fri, 15 Mar 2024 19:16:03 +0800 [thread overview]
Message-ID: <20240315111621.2263159-3-treapking@chromium.org> (raw)
In-Reply-To: <20240315111621.2263159-1-treapking@chromium.org>
Update the minimum voltage from 300000 uV to 400000 uV so it matches
the MT6315 datasheet.
Also update the minimum voltage for Vgpu regulator from 625000 uV to
400000 uV because the requested voltage could be lower than the minimum
voltage on the GPU OPP table when the MTK Smart Voltage Scaling (SVS)
driver is enabled.
Fixes: 260c04d425eb ("arm64: dts: mediatek: cherry: Enable MT6315 regulators on SPMI bus")
