Hi

We are using IMX6ULL for our custom board and observed that for the frequencies 792MHz & 528MHz , the voltage value is constant (1.275V) in 'userspace' mode.We had given the correct PMIC regulator name in 'cpu0' section of the dts file.We tried changing the content in section 'fsl,soc-operating-points ' of dtsi file also but whatever be the voltage value given in the above mentioned section, the voltage value remained 1.275V itself.Could you please tell us how to enable the DVFS feature?
