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. > Why? The name was selected according to the documentation on device "General > purpose analog-to-digital converter (GPADC)". Sigh, we simply don't care whether this ADC is general-purpose or not. The main thing it is ADC. > PS. Following your logic - "GPIO" need to renamed to "IO" everywhere ;P GPIO is well known and established abbreviation, contrasted to GPADC. Moreover, ePAPR spec lists "gpio" as a generic node name.
