Tool/software:
Hello TI Team,
We are working on a custom board based on an AM62x processor and we have connected PMIC and RTC on I2C0. Currently, We cannot persist the time after reboot.
I checked the reboot logs and found the below logs related to RTC. We are using PCA85073A external RTC.
5.845822] pinctrl-single f4000.pinctrl: pin PIN120 already requested by 20000000.i2c; cannot claim for 0-0051 [ 5.856020] pinctrl-single f4000.pinctrl: pin-120 (0-0051) status -22 [ 5.914547] pinctrl-single f4000.pinctrl: could not request pin 120 (PIN120) from group i2c0-default-pins on device pinctrl-single [ OK ] Started Network Time Synchronizatio[ 5.932126] rtc-pcf85063 0-0051: Error applying setting, reverse things back n.

Let me know if any other configuration is needed. Also, How can we set the date and time.
