PMIC RTC enable in jetson TX2

how to enable PMIC RTC in jetson Tx2,i also want to use RTC backup facility in my custom design through PMIC…

Any help will be appreciated?

I don’t catch what your want…the RTC is enabled by default. Do you want to use the backup battery for other usage?

There are two types of RTC one is tegra RTC and other is PMIC based RTC,is both are enabled by default??? i want to use PMIC based RTC

Do you mean the rtc clock time?
