Michal Lenc 9ebd7e525c imxrt: add support for ADC triggering by an external signal ... Config option IMXRT_ADCx_ETC can now be used to select an external HW trigger to be used instead of continous trigger. Continous trigger is used if IMXRT_ADCx_ETC = -1 (default option). Otherwise the source signal is routed through XBAR and used as a trigger. Hardware triggering is currently limited to maximum of 8 channels. HW trigger is automatically disabled if there are more than 8 channels. The external triggering was tested with PWM signal as a source.
