In that case I have to add all these fixed regulators.

In case of AM335X-EVM one dedicated supply (5v) feeding to all the input
supplies (vcc1-7 and vccio) of the regulators.

tps65910 PMIC have vcc1-7 and vccio input supplies which are feeding to
all the regulators. (like one - one and one - many).

Tps65910 regulator drivers registration fails if we not providing the
correct input supply with supply name. One option I can see is that
fixed voltage regulators. If we do this then total 21 (8 input supply
fixed regulators and others are out regulators) are present in the system.

If this is the correct approach then I will submit next version of patch.

Thanks
