75d8365c94 power: supply: tps65090-charger: Convert to platform remove callback returning void
The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is ignored (apart
from emitting a warning) and this typically results in resource leaks.
To improve here there is a quest to make the remove callback return
void. In the first step of this quest all drivers are converted to
.remove_new() which already returns void. Eventually after all drivers
are converted, .remove_new() is renamed to .remove().

Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.

While scanning the internet for MM8013 PDFs, I found one for a different
IC from Mitsumi, MM8118 at [1]. It turned out however, that when you
search through the PDF, the MM8118 text has an invsible text layer
containing "MM8013" underneath..

With some elbow grease, I was able to confirm that most of the registers
match between the two ICs. Based on that finding, introduce live battery
voltage readout, hw-decided charge behavior readout and max current
readout. Also, expand the existing POWER_SUPPLY_HEALTH reporting.

f8d7a3d211 power: supply: Add driver for pm8916 lbc
pm8916 LBC is a Linear Battery Charger hardware block in pm8916 PMIC.

This block implements simple CC/CV charging for Li-Po batteries.
The hardware has internal state machine to switch between modes and
works mostly autonomously, only needing the limits and targets to be
set to operate.

This driver allows setting limits and enabling the LBC block, monitoring
it's state.

098bce1838 power: supply: Add pm8916 VM-BMS support
This driver adds basic support for VM-BMS found in pm8916.

VM-BMS is a very basic fuel-gauge hardware block that is, sadly,
incapable of any gauging. The hardware supports measuring OCV in
sleep mode, where the battery is not in use, or measuring average
voltage over time when the device is active.

This driver implements basic value readout from this block.

58e4aacb74 power: supply: Propagate of_node to child device
Ensure that the dynamically created power supply device sets its
->of_node if the driver supplies one.  This brings it in line with
several other subsystems (see git grep 'of_node =.*parent.*of_node') and
allows easier identification of the device from udev rules and similar.

Before this patch:

389405146c power: supply: Remove redundant dev_err_probe() for platform_get_irq_byname()
There is no need to call the dev_err_probe() function directly to print
a custom message when handling an error from platform_get_irq_byname()
function as it is going to display an appropriate error message
in case of a failure.

6eca10a1c2 power: supply: 88pm860x_battery: fix the return value handle for platform_get_irq()
There is no possible for platform_get_irq() to return 0,
and the return value of platform_get_irq() is more sensible
to show the error reason.

The syscon_poweroff_register() doesn't do anything special, so it can use the
builtin_platform_driver() macro to eliminate boilerplate code.

8e511f42ac power: reset: nvmem-reboot-mode: quiet some device deferrals
Some errors are being logged that are really due to deferrals,
which is confusing to users. Use dev_err_probe() to handle when to log
at error level versus debug. This also has the added bonuses of logging
to devices_deferred and printing the error value.
