Add support for the LTC4162-L Li-Ion battery charger. The driver allows
reading back telemetry and to set some charging options like the input
current limit.

v2: Use microohm units instead of milliohm
Add interrupt support using smbalert
Support obtaining cell-count from devicetree
v3: Fix overflows in calculations involving resistor values
v4: Use attr_grp member to register attributes
Report input current/voltage for charger and make battery
voltage and current into sysfs attributes
Fine with me until we have a better way to solve the problem. IIUIC
you no longer have access to the hardware anyways? But you need to
document the custom sysfs nodes: Please document them in the
following file:
Documentation/ABI/testing/sysfs-class-power-ltc4162l
v5 is on its way with a description.
I currently don't have access to the hardware, so these changes were
only compile-tested.
[...]
+static int ltc4162l_remove(struct i2c_client *client)
+{
+ struct ltc4162l_info *info = i2c_get_clientdata(client);
+
+ sysfs_remove_group(&info->charger->dev.kobj, <c4162l_attr_group);
+
+ return 0;
+}
power-supply core automatically removes the sysfs groups specified
in power_supply_config.attr_grp.
Ah, good catch, missed that.
