Update Vgpu minimum voltage for MT8183, MT8186, MT8192, MT8195

[PATCH v2 0/4] Update Vgpu minimum voltage for MT8183, MT8186, MT8192, MT8195

Posted by Pin-yen Lin 6 months, 1 week ago

Use the minimum voltage listed on the Vgpu regulator datasheets instead
of the minimum value on GPU OPP table. This is because the requested
voltage could be lower when the MTK Smart Voltage Scaling (SVS) driver
is enabled.

Also update the incorrect MT6315 regulator usages on MT8192 and MT8195.

Changes in v2:
- Update Vgpu min voltage for MT8183, MT8186, MT8195
- Fix other usages of MT6315 buck1/buck3
