In the A64 SoC, it is possible to set drive-strength on GPIO pins.
The default for all ports is level 1. A better choice is level 3 as default on pins set as static drivers.
This can improve the noise level on the op-amps, but will require a re-calibration.
I think we should close this issue. It's not a necessity on A6/A7 boards, it was only meant as a way to get better temperature readings on A5. We can open it again if someone needs it.
