+*ADT7475 hwmon sensor.
+
+Required properties:
+- compatible: One of
+	"adi,adt7473"
+	"adi,adt7475"
+	"adi,adt7476"
+	"adi,adt7490"
+
+- reg: I2C address
+
+optional properties:
+
+- bypass-attenuator-all: Configures bypassing all voltage input attenuat=
ors.
+	This is only supported on the ADT7476 and ADT7490, this property does
+	nothing on other chips.
+		property present: Bit set to bypass all voltage input attenuators.
+		property absent: Registers left unchanged.
+
+- bypass-attenuator-inx: Configures bypassing individual voltage input
+	attenuators, where x is an integer from the set {0, 1, 3, 4}. This
+	is only supported on the ADT7476 and ADT7490, this property does nothin=
g
+	on other chips.
+		property present: Bit set to bypass specific voltage input attenuator
+			for voltage input x.
+		property absent: Registers left unchanged.
+
+Example:
+
+hwmon@2e {
+	compatible =3D "adi,adt7475";
+	reg =3D <0x2e>;
+	bypass-attenuator-all;
+	bypass-attenuator-in1;
