However, since neither TPS, nor AM57xx RTC are capable of being backedup by battery, we would like to maintain the "primary" rtc as mcp79410 rtc device. This also generates the following warnings in the bootlog highlighting the issue: [ 5.895445] rtc-ds1307 2-006f: /aliases ID 0 not available ... [ 6.476285] palmas-rtc 48070000.i2c:tps659038@58:tps659038_rtc: /aliases ID 1 not available So, add proper aliases to ensure that RTC order is always consistent to userspace immaterial of probe order.
