The AM3517 SOM-M2 module has a Seiko S35390 RTC attached to the I2C-1 interface.
I have some RTC errors during boot up and the /dev entry for the rtc is missing.
I see many others (online) have the same error messages, and many do not. Anyone know of a solution?
"rtc-s35390a 1-0030: error resetting chip"
"rtc-s35390a: probe of 1-0030 failed with error -5
"drivers/rtc/hctosys.c: unable to open rtc device (rtc0)"
