c788f6e6aa mfd: stmfx: Improve error message triggered by regulator fault in .remove()
Returning a non-zero value in an i2c remove callback results in the i2c
core emitting a very generic error message ("remove failed (-ESOMETHING),
will be ignored") and as the message indicates not further error handling
is done.

Instead emit a more specific error message and then return zero in
.remove().

The long-term goal is to make the i2c remove prototype return void, making
all implementations return 0 is preparatory work for this change.

f49f43371b mfd: intel_soc_pmic_crc: Set main IRQ domain bus token to DOMAIN_BUS_NEXUS
For the CRC PMIC we end up with multiple IRQ domains with the same fwnode.
One for the irqchip which demultiplexes the actual PMIC interrupt into
interrupts for the various cells (known as the level 1 interrupts);

And 2 more for the irqchips which are part of the crystal_cove_gpio
and crystal_cove_charger cells.

This leads to the following error being printed when
CONFIG_GENERIC_IRQ_DEBUGFS is enabled:
 debugfs: File '\_SB.I2C7.PMIC' in directory 'domains' already present!

Set the bus token of the main IRQ domain to DOMAIN_BUS_NEXUS to avoid
this error, this also allows irq_find_matching_fwspec() to find the
right domain if necessary.

Note all 3 domain registering drivers need to set the IRQ domain bus token.
This is necessary because the IRQ domain code defaults to creating
the debugfs dir with just the fwnode name and then renames it when
the bus token is set. So each one starts with the same default name and
all 3 must be given a different name to avoid problems when one of the
other drivers loads and starts with the same default name.

50904e9bd6 mfd: intel_soc_pmic_crc: Add crystal_cove_charger cell to BYT cells
The Crystal Cove PMIC has a pin which can be used to connect the IRQ of
an external charger IC. On some boards this is used and we need to have
a cell for this, with a driver which creates its own irqchip with
a single IRQ for the charger driver to consume.

The charger driver cannot directly consume the IRQ from the MFD level
irqchip because the PMIC has 2 levels of interrupts and the second
level interrupt status register, which is handled by the cell drivers,
needs to have the IRQ acked to avoid an IRQ storm.

254099d8fa watchdog: max77620: Add support for the max77714 variant
The MAX77714 is a MFD chip whose watchdog has the same programming
procedures as the MAX77620 watchdog, but most register offsets and bit
masks are different, as well as some features.

Support the MAX77714 watchdog by adding a variant description table holding
the differences.

All the features implemented by this driver are available on the MAX77714
except for the lack of a WDTOFFC bit. Instead of using a "HAS_*" flag we
handle this by holding in the cnfg_glbl2_cfg_bits struct field the bits
(i.e. the features) to enable in the CNFG_GLBL2 register. These bits differ
among the two models. This implementation allows to avoid any conditional
code, keeping the execution flow unchanged.

3e2e90fefc rtc: max77686: Remove unused code to read in 12-hour mode
The MAX77714 RTC chip is explicitly set to 24-hour mode in
max77686_rtc_probe() -> max77686_rtc_init_reg() and never changed back to
12-hour mode. Accordingly info->rtc_24hr_mode is set to 1 in the same place
and never modified later, so it is de facto a constant. Yet there is code
to read 12-hour time, which is unreachable.

Remove the unused variable, the unreachable code to manage 12-hour mode and
the defines that become unused due to the above changes.

9e444dbf27 iio: temperature: iqs620at-temp: Add support for V3 silicon
The vendor introduced an updated revision of IQS620A(T) silicon
which is backwards-compatible with previous revisions, the only
exception being the offset used to derive temperature.

Enable this new revision by returning the appropriate offset as
a function of the hardware number provided by the parent MFD.

67bfce0e01 ftrace: Fix s390 breakage from sorting mcount tables
The latest merge of the tracing tree sorts the mcount table at build time.
 But s390 appears to do things differently (like always) and replaces the
 sorted table back to the original unsorted one. As the ftrace algorithm
 depends on it being sorted, bad things happen when it is not, and s390
 experienced those bad things.
 
 Add a new config to tell the boot if the mcount table is sorted or not,
 and allow s390 to opt out of it.

6b9b641370 ftrace: Fix assuming build time sort works for s390
To speed up the boot process, as mcount_loc needs to be sorted for ftrace
to work properly, sorting it at build time is more efficient than boot up
and can save milliseconds of time. Unfortunately, this change broke s390
as it will modify the mcount_loc location after the sorting takes place
and will put back the unsorted locations. Since the sorting is skipped at
boot up if it is believed that it was sorted at run time, ftrace can crash
as its algorithms are dependent on the list being sorted.

Add a new config BUILDTIME_MCOUNT_SORT that is set when
BUILDTIME_TABLE_SORT but not if S390 is set. Use this config to determine
if sorting should take place at boot up.
