When looking for hardware that supports UIE via alarm irqs, I came across the Renesas Genmai board and its rtc-sh driver. The driver basically works but there is still a lot of cruft left which is not needed since the RTC core now uses the timerqueue. Patch 1 is actually a bugfix for DT systems. Without it, alarm interrupts don't work. I suggest backporting it to stable. The other patches are mostly removals. This is why the diffstat looks so nice. More descriptions in the individual patches. Looking forward to comments.
