+ltc2978
+
+Required properties:
+- compatible: should contain one of:
+ * "lltc,ltc2974"
+ * "lltc,ltc2977"
+ * "lltc,ltc2978"
+ * "lltc,ltc3880"
+ * "lltc,ltc3883"
+ * "lltc,ltm4676"
+- 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:
+ * ltc2974 : vout0 - vout3
+ * ltc2977 : vout0 - vout7
+ * ltc2978 : vout0 - vout7
+ * ltc3880 : vout0 - vout1
+ * ltc3883 : vout0
+ * ltm4676 : vout0 - vout1
+
+Example:
+ltc2978@5e {
+ compatible = "lltc,ltc2978";
+ reg = <0x5e>;
+ regulators {
+ vout0 {
+ regulator-name = "FPGA-2.5V";
+ };
+ vout2 {
+ regulator-name = "FPGA-1.5V";
+ };
+ };
+};
