yeah, right. Currently I want to drop following:

atmel,adc-drdy-mask, atmel,adc-status-register, atmel,adc-trigger-register, atmel,adc-channel-base

For the adc-num-channels, I'd like to leave it in dt parameters. It is a 
description for an adc capablity.

For the triggers, I am not decided. An obvious benifit to remove trigger 
in dt will save many lines of code.
