Fine with me. You may even rename pwm1_mode to pwm1_dac or use text strings as the values (say "pwm" and "dac") so as to make the interface self-explaining. Not a big deal anyway, and we obviously lack the knowledge of other chips with similar functionality to decide what the smartest move would be. We can always change it afterwards if such chips arise. I don't think it'll happen though, since DAC have completely disappeared from newer chips. -- Jean Delvare
