Does rock64 have a RTC

The main processor (RK3328) does not have a RTC as far as I can tell, but the RK805, which is the programmable DC-DC converter unit providing all the voltages the board needs does have one. I don't know if you can use it as an RTC for the board, or if it's primary purpose of existing is just to allow for time triggered poweron. The datasheet does list all the registers and such, so if you can poke the RK805 registers you might be able to find out. Just be careful what you poke as if you poke the wrong think you might fry something by setting a voltage you shouldn't. You have been warned™ ™.
