[PATCH 0/2] charger-manager: Use EXTCON Subsystem to control charger cable

[Chanwoo Choi]

This patchset add support EXTCON Subsystem in which charger-manager identify
the type of external connector and enable/disable charger(regulator) according
to the state of charger cable(external connector).

First patch control charger(regulator) of charger-manager when external
connector is attached or detached. If USB/TA cable is attached and thenE XTCON
subsystem notify the state of external connector to notifee(charger-manager)
which is registered in notifier chain of EXTCON, charger-manager enable charger
(regulator) for charging according to 'struct charger_cable'.

Second patch protect host device from over current. The charger-manager
set proper current limit of charger(regulator) for charging according to
type of charger cable when external connector is attached.

For example, if TA cable(external connector) is attached, charger-manager
enable charger('vinchg1' regulator) and set limit current within 65000~675000uA.

static struct charger_cable charger_cable_vinchg1[] = {
	{
		.extcon_name	= "max8997-muic",
		.name		= "USB",
		.min_uA		= 475000,
		.max_uA		= 475000 + 25000,
	}, {
		.extcon_name	= "max8997-muic",
		.name		= "TA",
		.min_uA		= 650000,
		.max_uA		= 650000 + 25000,
	},
};

static strcut charger_regulator nuri_regulators[] = {
	{
		.regulator_name	= "vinchg1",
		.cables		= charger_cable_vinchg1,
		.num_cables	= ARRAY_SIZE(charger_cable_vinchg1),
	},
};

static struct charger_desc nuri_charger_desc = {
	// ......

	.charger_regulators	= nuri_regulators,
	.num_charger_regulators	= ARRAY_SIZE(nuri_regulators),
};
