Subject: [PATCH v2 4/4] arm64: dts: mediatek: mt8186-corsola: Update min voltage constraint for Vgpu
Date: Fri, 15 Mar 2024 19:16:05 +0800 [thread overview]
Message-ID: <20240315111621.2263159-5-treapking@chromium.org> (raw)
In-Reply-To: <20240315111621.2263159-1-treapking@chromium.org>
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, so update the minimum voltage constraint from 600000 uV to
500000 uV as listed on the mt6366 datasheet.
Fixes: 8855d01fb81f ("arm64: dts: mediatek: Add MT8186 Krabby platform based Tentacruel / Tentacool")
