How regulator voltages are set

Hi,

 

We are currently trying to set the  PMIC(pfuze3000 A3) output voltage to 1.375V.  We tried setting the registers in u-boot but it gets overridden by the kernel during bootup. Currently, the only other method we know is by setting the operating-points tuple in the device tree. Is this correct method?

 

Best Regards,

Leonardo
