Subject: Automatical handling of /sys/class/rtc/rtcN/offset
Date: Tue, 26 May 2020 21:57:50 +0300	[thread overview]
Message-ID: <810d81d9-847d-a849-bf8e-49ea59ba6b83@gmail.com> (raw)

Dear all,

I have found that my RTC  (M41T00) is capable to make precise 
compensation of offset in the Control register.

Its driver, rtc-ds1307.c has support for such offset compensation and 
provide the /sys/class/rtc/rtc0/offset file.

Compensation tested and operate as expected, when I manually read/write 
offset value (in PPB) from/into the /sys/class/rtc/rtc0/offset file.

Does handling of such RTC offset already automatized somehow instead of 
doing this manually?

I ask for community, because do not want to invent another one wheel if 
there are something already implemented for such purpose.

Best wishes.
