+ Maximum frequencies from datasheet operating requirements.
+ Three values necessary to cover the 3 conversion modes.
+ * Frequency in normal mode (ADLPC=0, ADHSC=0)
+ * Frequency in high-speed mode (ADLPC=0, ADHSC=1)
+ * Frequency in low-power mode (ADLPC=1, ADHSC=0)
+
+ min-sample-time:
+ $ref: /schemas/types.yaml#/definitions/uint32
+ description:
+ Minimum sampling time in nanoseconds. This value has
+ to be chosen according to the conversion mode and the connected analog
+ source resistance (R_as) and capacitance (C_as). Refer the datasheet's
+ operating requirements. A safe default across a wide range of R_as and
+ C_as as well as conversion modes is 1000ns.
