Checking downstream it uses 0x61 for the ppid. This is also the case for all other descriptions of that RTC I could find. On the other hand, that does not describe the "alarm" register bank at 0x6100. Should it be added, if anything to match reg-names? I tried a quick test of the alarm on sa8540p-ride: $ echo $(date '+%s' -d '+ 10 seconds') > /sys/class/rtc/rtc0/wakealarm It logged the interrupt: 172: 3 0 0 0 0 0 0 0 pmic_arb 101777441 Edge pm8xxx_rtc_alarm -- Eric Chanudet
