Hi Marek

Currently, it misses regulator support in OPTEE.
But you can enable "manually" VDDIO3 and VDDIO4 in U-Boot console 
by using the following mw command: 

mw 44210000 300

There is also a dependency with this series https://patchwork.ozlabs.org/project/uboot/list/?series=468436
you must applied first.
