Okay... ut the Nomadik pin controller incidentally have a similar definition: NMK_GPIO_LOWEMI. By slashing the slew rate in half the EMI is of course reduced so that was another name for the same thing. Maybe this is something that should just be boolean? slewrate-reduced-slope; ? > Anybody object to me adding an argument to > pinconf_generic_parse_dt_config() so that an additional > pinconf_generic_dt_params array can be optionally passed in?
