+ - Mode 0: 7 single-ended voltage readings (IN0-IN6),
+ 1 temperature reading (internal)
+ - Mode 1: 8 single-ended voltage readings (IN0-IN7),
+ no temperature
+ - Mode 2: 4 pseudo-differential voltage readings
+ (IN0-IN1, IN3-IN2, IN4-IN5, IN7-IN6),

+ - Mode 3: 4 single-ended voltage readings (IN0-IN3),
+ 2 pseudo-differential voltage readings
+ (IN4-IN5, IN7-IN6),
+ 1 temperature reading (internal)
+
+If no operation mode is configured via device tree, the driver keeps the
+currently active chip operation mode (default is mode 0).
