    I didn't know how to express my disappointment from Oleksandr's inability 
to understand what I wanted to convey to him from 2 attempts... first, he 
changed the label instead of the node name, then he only dropped "twl6030_" 
prefix from the name. I should probably have been even more specific before.

    Sigh, we simply don't care whether this ADC is general-purpose or not.
The main thing it is ADC.

    GPIO is well known and established abbreviation, contrasted to GPADC.
Moreover, ePAPR spec lists "gpio" as a generic node name.

WBR, Sergei
