Let user set input current limit via sysfs. This is useful in case there
are multiple chargers connected to the device, each of which with its own
arbitrary maximum current which it can provide, some of which may provide
more than the default 500mA. In that case, userspace can listen for plug
events generated by each charger and adjust the current limit accordingly,
e.g. to permit battery to charge faster.
Note that the IINLIM is reset every time the bq25890 is disconnected from
a charger, so the userspace must adjust the limit repeatly on every plug
event.

The value returned by an i2c driver's remove function is mostly ignored.
(Only an error message is printed if the value is non-zero that the
error is ignored.)
So change the prototype of the remove function to return no value. This
way driver authors are not tempted to assume that passing an error to
the upper layer is a good idea. All drivers are adapted accordingly.
There is no intended change of behaviour, all callbacks were prepared to
return 0 before.

SAMA7G5 reset controller has 5 extra lines that goes to different devices
(3 lines to USB PHYs, 1 line to DDR controller, 1 line to DDR PHY
controller). These reset lines could be requested by different controller
drivers (e.g. USB PHY driver) and these controllers' drivers could
assert/deassert these lines when necessary. Thus add support for
reset_controller_dev which brings this functionality.

The maintenance charging is supposedly designed such that the
maintenance current compensates for the battery discharge curve,
and as the charging progress from CC/CV -> maintenance A ->
maintenance B states, we end up on a reasonable voltage to
restart ordinary CC/CV charging after the safety timer at the
maintenance B state exits.
However: old batteries discharge quicker, and in an old
battery we might not get to the expiration of the maintenance B
timer before the battery is completely depleted and the system
powers off with an empty battery.
This is hardly the desire of anyone leaving their phone in the
charger for a few days!
Introduce a second clause in both maintenance states such that
we exit the state and return to ordinary CC/CV charging if
the voltage drops below charge_restart_voltage_uv or 95%
if this is not defined for the battery.

The battery info contains a voltage indicating when the voltage
is so low that it is time to restart the CC/CV charging.
Make the AB8500 respect and prioritize this setting over the
hardcoded 95% threshold.
Break out the check into its own function and add some safeguards
so we do not run into unpredictable side effects.

Similar to the handling of cros_usbpd_charger_ec_command in commit 441d38c60f
("power: supply: cros_usbpd: Use struct_size() helper in kzalloc()"),
we thought a patch might be needed here as well.
Make use of the struct_size() helper instead of an open-coded version,
in order to avoid any potential type mistakes or integer overflows that,
in the worst scenario, could lead to heap overflows.

The functions power_supply_temp2resist_simple and power_supply_ocv2cap_simple
handle boundary conditions incorrectly.
The change was introduced in a4585ba205
("power: supply: core: Use library interpolation").
There are two issues: First, the lines "high = i - 1" and "high = i" in ocv2cap
have the wrong order compared to temp2resist. As a consequence, ocv2cap
sets high=-1 if ocv>table[0].ocv, which causes an out-of-bounds read.
Second, the logic of temp2resist is also not correct.
Consider the case table[] = {{20, 100}, {10, 80}, {0, 60}}.
For temp=5, we expect a resistance of 70% by interpolation.
However, temp2resist sets high=low=2 and returns 60.
