IRQ_TYPE_NONE is not correct here -> it should have some polarity - if
it had none, there'd be no interrupt, right?

Also I'm not seeing just zeroes coming from RTC after typing hwclock
on omap5-uevm. It's working on x15 though.

Nikolaus, is hwclock command working for you on omap5-uevm?

Well, yes and no. It appears it *was* working when tested last time
(we sometimes have months of delay for submitting patches upstream).

I have found an SD image with 4.3-rc6 with this patch in the dtb and
there it works. With 4.4-rc8 it does not work. hwclock command hangs for
10 seconds (I guess some timeout).

I have checked the dtb and in both cases it is interrupts = <8 0>;

xxd /sys/firmware/devicetree/base/ocp/i2c@48070000/palmas@48/rtc/interrupts
0000000: 0000 0008 0000 0000

So I think something has changed in the rtc driver or somewhere else.

BR,
Nikolaus
