+Texas Instruments' TLA2021/TLA2022/TLA2024 12-bit ADC driver
+
+Required properties:
+
+- compatible: should be one of:
+  "ti,tla2024"
+  "ti,tla2022"
+  "ti,tla2021"
+
+- reg: should contain the I2C Address of the device
+
+Required subnodes:
+
+The ADC channels are configured as subnodes of the ADC.
+The channels can be single-ended or differential, the input pins are
+also set in the subnode.
+
+Possible channels in TLA2024:
+  single: <0>, <1>, <2>, <3>
+  differential: <0 1>, <0 3>, <1 3>, <2 3>
+
+In TLA2021/TLA2022 only the differential channel <0 1> is allowed.
+
+Example:
+
+tla2024_0: adc0@49 {
+	compatible = "ti,tla2024";
+	reg = <0x49>;
+
+	v0@0 {
+		single-channel = <0>;
+	};
+
+	v1@1 {
+		single-channel = <1>;
+	};
+
+	v23@2 {
+		diff-channels = <2 3>;
+	};
+
+	v01@3 {
+		diff-channels = <0 1>;
+	};
+};
