| |
The MT8192 SoC specifies a maximum voltage for the GPU's digital supply of 0.88V and the GPU OPPs are declaring a maximum voltage of 0.80V.
In order to keep the GPU voltage in the safe range, change the maximum voltage for mt6315@7's vbuck1 to 0.80V as sending, for any mistake, 1.193V would be catastrophic.
