Hi!
I want to know how the SD card UHS-I can tell the processor to tell the PMIC to change the SD pull-up voltage from 3.3V to 1.8V.
Is this configurable inside the device tree?

Hello,
The engineer assigned is out for the rest of this week. Thank you for your patience.
Warm regards,

Hi Daniel,
The vqmmc-supply property contains the pointer to the voltage regulator responsible for voltage switching.
The voltage regulator node given below has the gpios property which contains the GPIO for controlling the voltage switch.

Thank you! I'm going to make sure that PMIC can handle the voltage output instead of an GPIO.
