6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Pin-yen Lin treapking@chromium.org
[ Upstream commit e9a6b8b5c61350535c7eb5ea9b2dde0d5745bd1b ]
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.
