Description

@flucas1

Using version 1.1 and the orange pi 5 plus, I get 2 rtc devices,
Older versions were providing only 1 rtc

rtc0, detected by the kernel as primary, is mapped to the driver rtc-efi, but this one is not providing any data,
rtc1, gives the real rtc data

cat /sys/class/rtc/*/name
rtc-efi rtc-efi.0
rtc-hym8563 6-0051

cat /sys/class/rtc/*/hctosys
