How regulator voltages are set

ioteng — Wed, 29 Jan 2020 08:39:52 GMT

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

attached Linux Manual.
