Hi Tiezhu,

Would you please help to put OF and OF_ADDRESS into one line as
following:
depends on OF && OF_ADDRESS.

Also please help to add them for PHY_MTK_TPHY.
And change the tile 'phy/mediatek: ...' as 'phy: mediatek: ...'

OK, no problem, I will do it.

Thanks,
Tiezhu


Thank you


+ depends on HAS_IOMEM

Why not add them into deconfig but here? In fact I don't know which way
is better and follow the kernel rule.

Vinod and Kishon, do you have any suggestion about this?
Putting them into a defconfig won't prevent random build errors
while putting them here will (or at least should).
