GPADC is the general purpose ADC present on twl6030.
The dt data is interrupt used to trigger end of ADC
conversion.

    Read my lips: the node should be called just "adc", not "gpadc".

       ^^^^^^^^^^^^ Are you sure?

Why? The name was selected according to the documentation on device 
"General purpose analog-to-digital converter (GPADC)".

PS. Following your logic - "GPIO" need to renamed to "IO" everywhere ;P

    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

How would you comment the following code, v3.10-rc7:
