-Maxim MAX14577/77836 Multi-Function Device
-
-MAX14577 is a Multi-Function Device with Micro-USB Interface Circuit, Li+
-Battery Charger and SFOUT LDO output for powering USB devices. It is
-interfaced to host controller using I2C.
-
-MAX77836 additionally contains PMIC (with two LDO regulators) and Fuel Gauge.
-For the description of Fuel Gauge low SOC alert interrupt see:
-../power/supply/max17040_battery.txt
-
-
-Required properties:
-- compatible : Must be "maxim,max14577" or "maxim,max77836".
-- reg : I2C slave address for the max14577 chip (0x25 for max14577/max77836)
-- interrupts : IRQ line for the chip.
-
-
-Required nodes:
- - charger :
- Node for configuring the charger driver.
- Required properties:
- - compatible : "maxim,max14577-charger"
- or "maxim,max77836-charger"
- - maxim,fast-charge-uamp : Current in uA for Fast Charge;
- Valid values:
- - for max14577: 90000 - 950000;
- - for max77836: 45000 - 475000;
- - maxim,eoc-uamp : Current in uA for End-Of-Charge mode;
- Valid values:
- - for max14577: 50000 - 200000;
- - for max77836: 5000 - 100000;
- - maxim,ovp-uvolt : OverVoltage Protection Threshold in uV;
- In an overvoltage condition, INT asserts and charging
- stops. Valid values:

- Valid values:
- - 4000000 - 4280000 (step by 20000);
- - 4350000;
-
-
-Optional nodes:
-- max14577-muic/max77836-muic :
- Node used only by extcon consumers.
- Required properties:
- - compatible : "maxim,max14577-muic" or "maxim,max77836-muic"
-
-- regulators :
- Required properties:
- - compatible : "maxim,max14577-regulator"
- or "maxim,max77836-regulator"
-
- May contain a sub-node per regulator from the list below. Each
- sub-node should contain the constraints and initialization information
- for that regulator. See regulator.txt for a description of standard
- properties for these sub-nodes.
-
- List of valid regulator names:
- - for max14577: CHARGER, SAFEOUT.
- - for max77836: CHARGER, SAFEOUT, LDO1, LDO2.
-
- The SAFEOUT is a fixed voltage regulator so there is no need to specify
- voltages for it.
-
