[PATCH 0/5] Add rtc support for rn5t618 mfd

[Andreas Kemnade]

In the variant rc5t619 the mfd has a rtc. This patchset adds
support for it. To do so it adds the missing register defines in 
rn5t618.h and general irq handling for that.
Probably the irq definitions are the same except missing rtc + charger
but due to missing information about that I do not add them.
There might be some oddity about the charger irq which should be 
researched when adding the charger subdevice.

The rtc driver itself is based on 
https://github.com/kobolabs/Kobo-Reader/blob/master/hw/imx6sll-clara/kernel.tar.bz2
but heavily reworked.

It was tested on the Kobo Clara HD.
