+ltc2978
+
+Required properties:
+- compatible: should contain one of:
+  * "lltc,ltc2972"
+  * "lltc,ltc2974"
+  * "lltc,ltc2975"
+  * "lltc,ltc2977"
+  * "lltc,ltc2978"
+  * "lltc,ltc2979"
+  * "lltc,ltc2980"
+  * "lltc,ltc3880"
+  * "lltc,ltc3882"
+  * "lltc,ltc3883"
+  * "lltc,ltc3884"
+  * "lltc,ltc3886"
+  * "lltc,ltc3887"
+  * "lltc,ltc3889"
+  * "lltc,ltc7880"
+  * "lltc,ltm2987"
+  * "lltc,ltm4664"
+  * "lltc,ltm4675"
+  * "lltc,ltm4676"
+  * "lltc,ltm4677"
+  * "lltc,ltm4678"
+  * "lltc,ltm4680"
+  * "lltc,ltm4686"
+  * "lltc,ltm4700"
+- reg: I2C slave address
+
+Optional properties:
+- regulators: A node that houses a sub-node for each regulator controlled by
+  the device. Each sub-node is identified using the node's name, with valid
+  values listed below. The content of each sub-node is defined by the
+  standard binding for regulators; see regulator.txt.
+
+Valid names of regulators depend on number of supplies supported per device:
+  * ltc2972 vout0 - vout1
+  * ltc2974, ltc2975 : vout0 - vout3
+  * ltc2977, ltc2979, ltc2980, ltm2987 : vout0 - vout7
+  * ltc2978 : vout0 - vout7
+  * ltc3880, ltc3882, ltc3884, ltc3886, ltc3887, ltc3889 : vout0 - vout1
+  * ltc7880 : vout0 - vout1
+  * ltc3883 : vout0
+  * ltm4664 : vout0 - vout1
+  * ltm4675, ltm4676, ltm4677, ltm4678 : vout0 - vout1
+  * ltm4680, ltm4686 : vout0 - vout1
+  * ltm4700 : vout0 - vout1
+
+Example:
+ltc2978@5e {
+	compatible = "lltc,ltc2978";
+	reg = <0x5e>;
+	regulators {
+		vout0 {
+			regulator-name = "FPGA-2.5V";
+		};
+		vout2 {
+			regulator-name = "FPGA-1.5V";
+		};
+	};
+};
