-MCP16502 PMIC
-
-Required properties:
-- compatible: "microchip,mcp16502"
-- reg: I2C slave address
-- lpm-gpios: GPIO for LPM pin. Note that this GPIO *must* remain high during
- suspend-to-ram, keeping the PMIC into HIBERNATE mode; this
- property is optional;
-- 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.

-Regulators 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)

-TPS65132 regulators
-
-Required properties:
-- compatible: "ti,tps65132"
-- reg: I2C slave address
-
-Optional Subnode:
-Device supports two regulators OUTP and OUTN. A sub node within the
- device node describe the properties of these regulators. The sub-node
- names must be as follows:
- -For regulator outp, the sub node name should be "outp".
- -For regulator outn, the sub node name should be "outn".
-
--enable-gpios:(active high, output) Regulators are controlled by the input pins.
- If it is connected to GPIO through host system then provide the
- gpio number as per gpio.txt.
--active-discharge-gpios: (active high, output) Some configurations use delay mechanisms
- on the enable pin, to keep the regulator enabled for some time after
- the enable signal goes low. This GPIO is used to actively discharge
- the delay mechanism. Requires specification of ti,active-discharge-time-us
--ti,active-discharge-time-us: how long the active discharge gpio should be
- asserted for during active discharge, in microseconds.
-
-Each regulator is defined using the standard binding for regulators.
-
