ECs implementing the v2 command will not stop charging when the end
threshold is reached. Instead they will begin discharging until the
start threshold is reached, leading to permanent charge and discharge
cycles. This defeats the point of the charge control mechanism.
Avoid the issue by hiding the start threshold on v2 systems.
Instead on those systems program the EC with start == end which forces
the EC to reach and stay at that level.
v1 does not support thresholds and v3 works correctly,
at least judging from the code.

Fix set charge current limits for devices which allow to set the lowest

is below lowest limit, the index equals current_limit_map_size which leads

however may be non-essential to the system's operation,

Instead of looping through all properties known to be supported by the
psy, loop over all known properties and decide based on the return value
of power_supply_get_property() whether the property existed.
This makes the code shorter now and even more so when power supply
extensions are added.
It also simplifies the locking, as it can all happen inside
power_supply_get_property().

POWER_SUPPLY_PROP_CHARGE_BEHAVIOUR
Currently an uevent contains the same string representation of a
property as sysfs. However for POWER_SUPPLY_PROP_CHARGE_BEHAVIOUR this
is specially formatted to indicate all possible values.
This doesn't make sense for uevents and complicates parsing.
Instead only include the currently active value in uevents.
As currently no in-tree driver uses POWER_SUPPLY_PROP_CHARGE_BEHAVIOUR
this change is not a problem.
Soon the property will actually be used so fix the formatting before
that happens.

Pull timer updates from Thomas Gleixner:
"A rather large update for timekeeping and timers:
- The final step to get rid of auto-rearming posix-timers
posix-timers are currently auto-rearmed by the kernel when the
signal of the timer is ignored so that the timer signal can be
delivered once the corresponding signal is unignored.
This requires to throttle the timer to prevent a DoS by small
intervals and keeps the system pointlessly out of low power states
for no value. This is a long standing non-trivial problem due to
the lock order of posix-timer lock and the sighand lock along with
life time issues as the timer and the sigqueue have different life
time rules.
Cure this by:
- Embedding the sigqueue into the timer struct to have the same
life time rules. Aside of that this also avoids the lookup of
the timer in the signal delivery and rearm path as it's just a
always valid container_of() now.
- Queuing ignored timer signals onto a seperate ignored list.
- Moving queued timer signals onto the ignored list when the
signal is switched to SIG_IGN before it could be delivered.
- Walking the ignored list when SIG_IGN is lifted and requeue the
signals to the actual signal lists. This allows the signal
delivery code to rearm the timer.
This also required to consolidate the signal delivery rules so they
are consistent across all situations. With that all self test
scenarios finally succeed.
- Core infrastructure for VFS multigrain timestamping
This is required to allow the kernel to use coarse grained time
stamps by default and switch to fine grained time stamps when inode
attributes are actively observed via getattr().
These changes have been provided to the VFS tree as well, so that
the VFS specific infrastructure could be built on top.
- Cleanup and consolidation of the sleep() infrastructure
- Move all sleep and timeout functions into one file
- Rework udelay() and ndelay() into proper documented inline
functions and replace the hardcoded magic numbers by proper
defines.
- Rework the fsleep() implementation to take the reality of the
timer wheel granularity on different HZ values into account.
Right now the boundaries are hard coded time ranges which fail
to provide the requested accuracy on different HZ settings.
- Update documentation for all sleep/timeout related functions
and fix up stale documentation links all over the place
- Fixup a few usage sites
- Rework of timekeeping and adjtimex(2) to prepare for multiple PTP
clocks
A system can have multiple PTP clocks which are participating in
seperate and independent PTP clock domains. So far the kernel only
considers the PTP clock which is based on CLOCK TAI relevant as
that's the clock which drives the timekeeping adjustments via the
various user space daemons through adjtimex(2).
The non TAI based clock domains are accessible via the file
descriptor based posix clocks, but their usability is very limited.
They can't be accessed fast as they always go all the way out to
the hardware and they cannot be utilized in the kernel itself.
As Time Sensitive Networking (TSN) gains traction it is required to
provide fast user and kernel space access to these clocks.
The approach taken is to utilize the timekeeping and adjtimex(2)
infrastructure to provide this access in a similar way how the
kernel provides access to clock MONOTONIC, REALTIME etc.
Instead of creating a duplicated infrastructure this rework
converts timekeeping and adjtimex(2) into generic functionality
which operates on pointers to data structures instead of using
static variables.
This allows to provide time accessors and adjtimex(2) functionality
for the independent PTP clocks in a subsequent step.
- Consolidate hrtimer initialization
hrtimers are set up by initializing the data structure and then
seperately setting the callback function for historical reasons.
That's an extra unnecessary step and makes Rust support less
straight forward than it should be.
Provide a new set of hrtimer_setup*() functions and convert the
core code and a few usage sites of the less frequently used
interfaces over.
The bulk of the htimer_init() to hrtimer_setup() conversion is
already prepared and scheduled for the next merge window.
- Drivers:
- Ensure that the global timekeeping clocksource is utilizing the
cluster 0 timer on MIPS multi-cluster systems.
Otherwise CPUs on different clusters use their cluster specific
clocksource which is not guaranteed to be synchronized with
other clusters.
- Mostly boring cleanups, fixes, improvements and code movement"

If the power supply type is not set it defaults to "Unknown" and upower
does not recognise it. In turn battery monitor applications do not see a
battery. Setting to POWER_SUPPLY_TYPE_BATTERY fixes this.

WCN6855 (also known as QCA6490) is similar to the already supported
QCA6390 but takes in two more supplies so add a new vregs list for it.
On sm8450-hdk it also requires a short assert of the xo-clk pin so add
handling for it in a dedicated unit.
As we now have a separate set of targets for this variant, store the
pointer to the targets struct associated with a model in the device
match data.

This driver uses various OF-specific functions and depends on phandle
parsing. There's no reason to make it available to non-OF systems so add
a relevant dependency switch to its Kconfig entry.

After commit 0edb555a65d1 ("platform: Make platform_driver::remove()
return void") .remove() is (again) the right callback to implement for
platform drivers.
Convert all platform drivers below drivers/power/ to use .remove(), with
the eventual goal to drop struct platform_driver::remove_new(). As
.remove() and .remove_new() have the same prototypes, conversion is done
by just changing the structure member name in the driver initializer.
While touching these files, make indention of the struct initializer
consistent in several files.

The battery capacity calibration function continues to be a source of
bugs for end users, especially when coming out of suspend. This occurs
when the device has incorrect readings for voltage, and causes the
current code to set fully charged capacity incorrectly.
Add checks to ensure we don't attempt a capacity calibration when we
have invalid voltage values or no battery present, and remove the code
that attempts to automatically set the fully charged capacity in lieu of
making the value writeable. This way userspace is able to adjust the
fully charged capacity for a degraded battery.

The driver has a thread that checks the battery every 8 seconds. Stop
this thread during device suspend as while the device is suspended not
all values seem to be read correctly (such as battery voltage). The
resume function triggers the thread to start again.
