this looks wrong. Regulators should always be named with the name
used in schematics and also, according to the rk3288-evb schematics
I have here, the saradc uses vcc_18 directly which comes from either
the rk808 or act8846 pmics (depending on the board version).

So taking the above into account
	vref-supply = <&vcc_18>; ?

OK,  I don't have software to check that schematics...
Agree and i will send a new patch.
