Downstream defines minimal voltage as 3.0 V, while when OnePlus 6 was
introduced to Linux mainline, the value was fixed to maximum 3.3V.

Tested for ~ 1 month. Seems to work well, no visible issues anywhere.

A datasheet tells me this is out of spec for this wireless chip
As I don't have the datasheet, can you clarify if the 3.3 - 3.312V is
the correct range which should be kept?
Thanks
