      1MCP16502 PMIC
      2
      3Required properties:
      4- compatible: "microchip,mcp16502"
      5- reg: I2C slave address
      6- lpm-gpios: GPIO for LPM pin. Note that this GPIO *must* remain high during
      7	     suspend-to-ram, keeping the PMIC into HIBERNATE mode; this
      8	     property is optional;
      9- regulators: A node that houses a sub-node for each regulator within
     10              the device. Each sub-node is identified using the node's
     11              name. The content of each sub-node is defined by the
     12              standard binding for regulators; see regulator.txt.

     14Regulators of MCP16502 PMIC:
     151) VDD_IO	- Buck (1.2 - 3.7 V)
     162) VDD_DDR	- Buck (0.6 - 1.85 V)
     173) VDD_CORE	- Buck (0.6 - 1.85 V)
     184) VDD_OTHER	- BUCK (0.6 - 1.85 V)
     195) LDO1		- LDO  (1.2 - 3.7 V)
     206) LDO2		- LDO  (1.2 - 3.7 V)
     21
     22Regulator modes:
     232 - FPWM: higher precision, higher consumption
     244 - AutoPFM: lower precision, lower consumption
     25
     26Each regulator is defined using the standard binding for regulators.
