cpu/kinetis/periph: adc_sample() now returns int32_t 2020-01-10 14:13:14 +01:00

dd2fad6b9b kinetis: ADC: Add hardware averaging configuration 
This allows a board configuration to select which kind of averaging
should be applied to the pin instead of always using 32 sample average.
Very high impedance sources may need to disable hardware averaging in
order to give correct values, the on-chip temperature sensor is one such
signal source.

b61eeb9fe0 kinetis: Allow per-board config of ADC ref 
ADC reference can be external pin or internal VREF module on most
Kinetis CPUs.
