Maybe this problem is only relevant for the S35390A and PCF8563 chip which
both lack the UIE support needed by hwclock. Both have only alarm triggers
in a minute accuracy according to the driver source code.
AFAIK the rtc framework should then emulate this event somehow.
I don't think so. When the rtc chip is not able to trigger an event with a
one second resolution - how can you emulate that?
CONFIG_RTC_INTF_DEV_UIE_EMUL emulates it by polling the RTC.
Just booted my NAS box and /boot/config-4.19.0-5-marvell contains
# CONFIG_RTC_INTF_DEV_UIE_EMUL is not set
Would be cool when this would make hwclock happy.
Best regards,
Oliver
