Yes, according to: https://github.com/AndreiLux/Perseus-S3/blob/master/arch/arm/mach-exynos/mach-smdk5250.c#L133

Sorry, i cannot. The board has lots of jumpers, which choose between fixed voltage and regulators for different components,
according to board's manual, but the manual is very poor IMHO, and i don't understand how to use them. And i use default,
fixed-voltage configuration.
One of my colleagues tried to get it working, but failed. It actually requires more time, and IIRC you need to bring up i2c before
you can drive regulators.
So can we leave it as it is for now? At least it works, and this is much better than no ethernet support at all.

Me neither, i wrote GPIO settings according to chip datasheet i have. They are actually chip-specific, but i wrote them in board
file because on different boards you may use different banks, and therefore different pins. Or, if you don't use SROMc at all, you
can configure all pins to do something else.
