Hi igor,

Thank you for your response.

We want to increase battery coin cell life by using external RTC on im6ul.

Please let us share your thought regarding external RTC. Is it worthful to use external RTC or not ?

Hi igor,

I checked the RTC driver in kernel. but this RTC driver is for PCF8523 and We are using PCF8526A. These both ICs are having different I2C register map. So I am not able to use this driver.

Can you please point out the proper RTC driver for PCF8526A ?
