applies to all 3 patches: we require real names both in the patch/mail from 
as well as the Signed-off-by line, see [0] at number 11. To my untrained eye 
the name given doesn't look like a real name, please correct me if I'm 
wrong.

Not 100% sure, but I guess this does not need to be duplicated.
The supply is named vcc_lan in all board revisions only the supplying 
regulator seems different, so it should be enough to point the vcc_lan 
phandle to the correct regulator in the relevant file, but the gmac 
assignment could stay in the main file?

the phandle name is to generic, as this is part of the act8846 and not 
something generic. So please name the phandle act8846_regulators / 
act8846_regs or so.
