Hi Neil and Guillaume,

the hint from the "meson-g12a-sei510: add regulators" patch would be
great here as well:
  Still missing
  * VDD_EE (0.8V - PWM controlled)
  * VDD_CPU(PWM controlled)
  * VDDQ1_5

I'm not sure whether this board also has VDDQ1_5 though, but VDD_EE
and VDD_CPU should be very similar (or even identical)

mine has a 5V DC in. can you please check this on your board?
