+MCP16502 PMIC
+
+Required properties:
+- compatible: "microchip,mcp16502"
+- reg: I2C slave address
+- lpm-gpios: GPIO for LPM pin. Note that this GPIO *must* remain high duri=
ng
+	     suspend-to-ram, keeping the PMIC into HIBERNATE mode.
+- regulators: A node that houses a sub-node for each regulator within
+              the device. Each sub-node is identified using the node's
+              name. The content of each sub-node is defined by the
+              standard binding for regulators; see regulator.txt.
+
+Regualtors of MCP16502 PMIC:
+1) VDD_IO	- Buck (1.2 - 3.7 V)
+2) VDD_DDR	- Buck (0.6 - 1.85 V)
+3) VDD_CORE	- Buck (0.6 - 1.85 V)
+4) VDD_OTHER	- BUCK (0.6 - 1.85 V)
+5) LDO1		- LDO  (1.2 - 3.7 V)
+6) LDO2		- LDO  (1.2 - 3.7 V)
+
+Regulator modes:
+2 - FPWM: higher precision, higher consumption
+4 - AutoPFM: lower precision, lower consumption
+
+Each regulator is defined using the standard binding for regulators.
