Hi,
Datasheet of each i.MX6 has an Absolute Maximum Ratings for each VDD_xxx_CAP signal.
But it has no operating range for it. Only minimal value is in comment of each VDD_xxx_IN.
The other hands, another documents and community comment has a different value for VDD_xxx_CAP.

Which is a correct answer of the operating range for VDD_xxx_CAP?
Best regards,
Ishii.
Hello,
Please use the Table, named “Operating Ranges” in the corresponding DataSheets
and footnotes under the Table for allowed voltages ranges.
The maximum VDD_xxx_CAP values may be taken from the Table for the case
“Run mode: LDO bypassed”.
Note, the recommended settings may be found as Linux CPU frequency working
point settings in the DTS files. Please refer to Chapter 23 [CPU Frequency Scaling
(CPUFREQ) Driver] of i.MX Linux® Reference Manual.
Have a great day,
Yuri
