if the rtc button cell is on low voltage this can result in a permanent bootloop in u-boot because V2F Register is permanent set. ### Warning: temperature compensation has stopped ### Warning: Voltage low, data is invalid resetting ...

I'm curious, how is the call tree here? I don't see the dm_rtc_get() being called during boot. Basically, you are now just ignoring the error.
I use dm_rtc_get() in a modified boot/bootm.c to check for a End-Off Live booting date. Just to prevent that testers uses devices with out-dated images.
So if this only affects me so this patch can be ignored.
