- atmel,min-sample-rate-hz: Minimum sampling rate, it depends on SoC.
- atmel,max-sample-rate-hz: Maximum sampling rate, it depends on SoC.
- atmel,startup-time-ms: Startup time expressed in ms, it depends on SoC.
- atmel,trigger-edge-type: One of possible edge types for the ADTRG hardware
trigger pin. When the specific edge type is detected, the conversion will
start. Possible values are rising, falling, or both.
This property uses the IRQ edge types values: IRQ_TYPE_EDGE_RISING ,
IRQ_TYPE_EDGE_FALLING or IRQ_TYPE_EDGE_BOTH
