commit 81af7f2342d162e24ac820c10e68684d9f927663 upstream.
Round constant_charge_voltage writes down to the first supported lower
value, rather then rounding them up to the first supported higher value.
This fixes e.g. writing 4250000 resulting in a value of 4350000 which
might be dangerous, instead writing 4250000 will now result in a safe
4200000 value.

commit b34ce4a59cfe9cd0d6f870e6408e8ec88a964585 upstream.
info->max_cv is in millivolts, divide the microvolt value being written
to constant_charge_voltage by 1000 *before* clamping it to info->max_cv.
Before this fix the code always tried to set constant_charge_voltage
to max_cv / 1000 = 4 millivolt, which ends up in setting it to 4.1V
which is the lowest supported value.

commit bf9d5cb588755ee41ac12a8976dccf44ae18281b upstream.
The driver returns -ENODEV when the firmware battmrg service hasn't
started yet, while per-se -ENODEV is fine, we usually use -EAGAIN to
tell the user to retry again later. And the power supply core uses
-EGAIN when the device isn't initialized, let's use the same return.
This notably causes an infinite spam of:
thermal thermal_zoneXX: failed to read out thermal zone (-19)
because the thermal core doesn't understand -ENODEV, but only
considers -EAGAIN as a non-fatal error.
While it didn't appear until now, commit [1] fixes thermal core
and no more ignores thermal zones returning an error at first
temperature update.

[ Upstream commit 1e0fb113646182e073539db96016b00cfeb18ecc ]
The of_match shall correspond to the name of the regulator subnode,
or the deprecated `regulator-compatible` property must be used:
failing to do so, the regulator won't probe (and the driver will
as well not probe).
Since the devicetree binding for this driver is actually correct
and wants DTs to use the "usb-otg-vbus-regulator" subnode name,
fix this driver by aligning the `of_match` string to what the DT
binding wants.

power_supply_uevent() which is called to emit a udev event on device
deletion attempts to use the power_supply_battery_info structure,
which is device-managed and has been freed before this point.
Fix this by not generating all battery/charger properties when the
device is about to be removed. This also avoids generating errors
when trying to access the hardware in hot-unplug scenarios.

Similar to the rk817 codec alias that was missing, the rk817 charger
driver is missing a module alias as well. This absence prevents the
driver from autoprobing on OF systems when it is built as a module.

When building with clang 18 I see the following warning:
| drivers/power/reset/vexpress-poweroff.c:124:10: warning: cast to smaller integer type 'enum vexpress_reset_func' from 'const void *' [-Wvoid-pointer-to-enum-cast]
| 124 | switch ((enum vexpress_reset_func)match->data) {
This is due to the fact that `match->data` is a void* while `enum vexpress_reset_func`
has the size of an int. This leads to truncation and possible data loss.

The BlueField power handling driver (pwr-mlxbf.c) provides
functionality for both BlueField-2 and BlueField-3 based
platforms. This driver also depends on the SoC-specific
BlueField GPIO driver, whether gpio-mlxbf2 or gpio-mlxbf3.
This patch extends the Kconfig definition to include the

I had the following weird phenomena on a mobile phone: while
the capacity in /sys/class/power_supply/ab8500_fg/capacity
would reflect the actual charge and capacity of the battery,
only 1/3 of the value was shown on the battery status
indicator and warnings for low battery appeared.
It turns out that UPower, the Freedesktop power daemon,
will average all the power supplies of type "battery" in
/sys/class/power_supply/* if there is more than one battery.
For the AB8500, there was "battery" ab8500_fg, ab8500_btemp
and ab8500_chargalg. The latter two don't know anything
about the battery, and should not be considered. They were
however averaged and with the capacity of 0.
Flag ab8500_btemp and ab8500_chargalg with type "unknown"
so they are not averaged as batteries.
Remove the technology prop from ab8500_btemp as well, all
it does is snoop in on knowledge from another supply.
After this the battery indicator shows the right value.

When the power supply device being registered supports a temperature
readout, the core registers a thermal zone for it. The thermal core
would register a hwmon device for that unless told otherwise.
When CONFIG_POWER_SUPPLY_HWMON is enabled, the power supply core creates
a hwmon device. This results in a second entry, one which has a better
name than the one registered through the thermal framework. It could
potentially have readouts other than temperature.
To simplify the result, tell the thermal framework to not register a
hwmon device if CONFIG_POWER_SUPPLY_HWMON is enabled. The result is
one hwmon device with all the readings the device supports.

The DT of_device.h and of_platform.h date back to the separate
of_platform_bus_type before it as merged into the regular platform bus.
As part of that merge prepping Arm DT support 13 years ago, they
"temporarily" include each other. They also include platform_device.h
and of.h. As a result, there's a pretty much random mix of those include
files used throughout the tree. In order to detangle these headers and
replace the implicit includes with struct declarations, users need to
explicitly include the correct includes.

It is quite uncommon to use a driver helper with parameters like *pdev
and __iomem *base. It is much cleaner and close to today's standards to
provide the per-device driver structure and then access its
internals. Let's do this with the helper which returns the power on
reason. While we change the parameters, we can as well rename the
function from at91_reset_status() to at91_reset_reason() to be more
accurate with what the helper actually does, and finally because we don't
really need the pdev argument in this helper besides for printing the
reset reason, we can move the dev_info() call into the probe.
All these modifications prepare the introduction of a sysfs entry to
access this information. This way the diff will be much smaller. Thus,
there is no intended functional change.

For PM8941 we don't have a defined field to store the reset reason.
Support wrapping pwrkey and resin, but without writing the reset
reason.

Add a driver for the SMB2 charger block found in the Qualcomm PMI8998
and PM660.
This driver is capable of utilising Qualcomm's Automatic Power Source
Detection (APSD) BC1.2 implementation, as well as Automatic Input
Current Limiting (AICL) to configure the maximum input current
limit of DCP (wall) chargers.
Quick Charge is not currently supported.
Most devices using the smb2 charger have a secondary dedicated charger
chip which is used in parallel to enable faster charger without
overheating. However, not all do, as a result to ensure safety until
these are supported, the maximum current is limited to ~1A via the
FAST_CHARGE_CURRENT_CFG register.

The rt5033-battery fuelgauge can't get a status by itself. The rt5033-charger
can, let's get this value.
To get the charger as a "supplier" from the devicetree, the "of_node" needs
to be initiated.
Additionally, in the probe function replace dev_err() with dev_err_probe(),
this will avoid printing an error for -EPROBE_DEFER when the battery driver
probes before the charger driver.

Move struct rt5033_battery from the mfd header into the battery driver because
it's not used by others.
Within struct rt5033_battery, remove the line "struct rt5033_dev *rt5033;"
because it doesn't get used.
In rt5033.h, remove #include <linux/power_supply.h>, it's not necessary
anymore.
In rt5033_battery.c, remove #include <linux/mfd/rt5033.h>, it's not necessary
anymore either. Instead add #include <linux/regmap.h> and

This patch adds device driver of Richtek RT5033 PMIC. The driver supports
switching charger. rt5033 charger provides three charging modes. The charging
modes are pre-charge mode, fast charge mode and constant voltage mode. They
vary in charge rate, the charge parameters can be controlled by i2c interface.
