1 Maxim MAX14577/77836 Multi-Function Device
3 MAX14577 is a Multi-Function Device with Micro-USB Interface Circuit, Li+
4 Battery Charger and SFOUT LDO output for powering USB devices. It is
5 interfaced to host controller using I2C.
7 MAX77836 additionally contains PMIC (with two LDO regulators) and Fuel Gauge.

48 - compatible : "maxim,max14577-regulator"
49 or "maxim,max77836-regulator"
51 May contain a sub-node per regulator from the list below. Each
52 sub-node should contain the constraints and initialization information
53 for that regulator. See regulator.txt for a description of standard
54 properties for these sub-nodes.
56 List of valid regulator names:
57 - for max14577: CHARGER, SAFEOUT.
58 - for max77836: CHARGER, SAFEOUT, LDO1, LDO2.
60 The SAFEOUT is a fixed voltage regulator so there is no need to specify
