[ Upstream commit 202ac22b8e2e015e6c196fd8113f3d2a62dd1afc ]
On some Dell XPS 13 (9345) variants, the battery used is lithium-polymer
based. Currently, this is reported as unknown technology due to the entry
missing.
[ 4083.135325] Unknown battery technology 'LIP'
Add another check for lithium-polymer in the technology parsing callback
and return that instead of unknown.

[ Upstream commit 58ae036172b5f051a19a32eba94a3e5eb37bf47e ]
From the datasheet of the MAX17201/17205, the LSB should be "5.0μVh/RSENSE".
The current computation sets it at 0.5mAh=5.0μVh/10mOhm, which does not take
into account the value of rsense (which is in 10µV steps) which can be
different from 10mOhm.
Change the computation to fit the specs.

[ Upstream commit 6c5393771c50fac30f08dfb6d2f65f4f2cfeb8c7 ]
Unloading and reloading the driver (e.g. when built as a module)
currently leads to errors trying to enable wake IRQ since it's already
enabled.
Use devm to manage this for us so it correctly gets disabled when
removing the driver.
Additionally, call device_init_wakeup() so that charger attach/remove
will trigger a wakeup by default.

When the kernel is not configured CONFIG_OF, the max14577_charger_dt_init

-ENODATA instead of potentially passing a NULL pointer to PTR_ERR.

[ Upstream commit f16d9fb6cf03fdbdefa41a8b32ba1e57afb7ae3d ]
Multiple applications may access the battery gauge at the same time, so
the gauge may be busy and EBUSY will be returned. The driver will set a
flag to record the EBUSY state, and this flag will be kept until the next
periodic update. When this flag is set, bq27xxx_battery_get_property()
will just return ENODEV until the flag is updated.
Even if the gauge was busy during the last accessing attempt, returning
ENODEV is not ideal, and can cause confusion in the applications layer.
Instead, retry accessing the I2C to update the flag is as expected, for
the gauge typically recovers from busy state within a few milliseconds.
If still failed to access the gauge, the real error code would be returned
instead of ENODEV (as suggested by Pali Rohár).

This removes two cases of explicit NUL padding that now causes warnings
because of '-Wunterminated-string-initialization' being part of -Wextra
in gcc-15.
Gcc is being silly in this case when it says that it truncates a NUL
terminator, because in these cases there were _multiple_ NUL characters.
But we can get rid of the warning by just simplifying the two
initializers that trigger the warning for me, so this does exactly that.
I'm not sure why the power supply code did that odd
.attr_name = #_name "\0",
pattern: it was introduced in commit 2cabeaf15129 ("power: supply: core:
Cleanup power supply sysfs attribute list"), but that 'attr_name[]'
field is an explicitly sized character array in a statically initialized
variable, and a string initializer always has a terminating NUL _and_
statically initialized character arrays are zero-padded anyway, so it
really seems to be rather extraneous belt-and-suspenders.
The zero_uuid[16] initialization in drivers/md/bcache/super.c makes
perfect sense, but it isn't necessary for the same reasons, and not
worth the new gcc warning noise.

Commit b35108a51cf7 ("jiffies: Define secs_to_jiffies()") introduced
secs_to_jiffies(). As the value here is a multiple of 1000, use
secs_to_jiffies() instead of msecs_to_jiffies() to avoid the
multiplication
This is converted using scripts/coccinelle/misc/secs_to_jiffies.cocci with
the following Coccinelle rules:

Commit f3974aca381e ("power: supply: bq27xxx: do not report bogus zero
values") breaks property reporting on chips which are reporting normal
values. During testing, excessive emphasis was evidently placed on the
chip with non-working conditions, and not enough testing was done on a
battery that had normal state.
A correct fix will be submitted in a separate patch.

The charge input threshold voltage register on the MAX77693 PMIC accepts
four values: 0x0 for 4.3v, 0x1 for 4.7v, 0x2 for 4.8v and 0x3 for 4.9v.
Due to an oversight, the driver calculated the values for 4.7v and above
starting from 0x0, rather than from 0x1 ([(4700000 - 4700000) / 100000]
gives 0).
Add 1 to the calculation to ensure that 4.7v is converted to a register
value of 0x1 and that the other two voltages are converted correctly as
well.

When registering a power-supply device, either a of_node or the more
recent fwnode can be supplied. Since fwnode can also contain an of_node,
let's try to get rid of it.

patch, there's no one left to call the set_charged method.

On the bq27x00 and bq27x10 variants, a number of conditions may reset the value
stored in the NAC register. This will cause capacity, energy, and charge to
report the value 0, even when the battery is full. On the other hand, the chip
also provides a flag, EDVF, which accurately detects the true battery empty
condition, when capacity, charge, and energy are really 0. Therefore, discard
readings for these properties if their value is 0 while EDVF is unset.
Tested on the Nokia N900 with bq27200.
