Move the Lenovo Yogabook YB1-X9x fuel-gauge instantiation code over to
the x86-android-tablets module, which already deals with this for various
other devices.
This removes the need to have a special intel_cht_int33fe_microb module
just for Lenovo Yogabook YB1-X9x laptops.

The intel_cht_int33fe driver is intended to deal with ACPI INT33FE
firmware-nodes on Cherry Trail devices with a Whiskey Cove PMIC.
The original version of the driver only dealt with the GPD win and
GPD pocket boards where the WC PMIC is connected to a TI BQ24292i charger,
paired with a Maxim MAX17047 fuelgauge + a FUSB302 USB Type-C Controller +
a PI3USB30532 USB switch, for a fully functional Type-C port.
Later it was split into a Type-C and a Micro-B variant to deal with
the Lenovo Yoga Book YB1-X90 / Lenovo Yoga Book YB1-X91 boards where
the ACPI INT33FE firmware-node only describes the TI BQ27542 fuelgauge.
Currently the driver differentiates between these 2 models by counting
the number of I2cSerialBus resources in the firmware-node.
There are a number of problems with this approach:
1. The driver autoloads based on the acpi:INT33FE modalias causing it
to get loaded on almost all Bay Trail and Cherry Trail devices. It
checks for the presence of a WC PMIC, so it won't bind but the loading
still wastes time and memory.
2. Both code paths in the driver are really only designed for a single
board and have harcoded various assumptions about these boards, if
another design matching the current checks ever shows up the driver
may end up doing something completely wrong.
Avoid both issues by switching to using DMI based autoloading of
the module, which has neither of these problems.
Note this splits the previous intel_cht_int33fe kernel module into two
modules: intel_cht_int33fe_typec and intel_cht_int33fe_microb, one for
each model.

Minor charger / fuel-gauge improvements:
1. Make some of the names of charger / fuel-gauge related globals more
generic in preparation for also using them on other boards.
2. Update the dev_name on the Asus ME176C and TF103C to reflect that these
are using the bq24297 variant of the bq24190 family.
3. During review of the ug3105 driver the "upi,rsns-microohm" property was
renamed to "upisemi,rsns-microohm" as "upisemi" is the correct vendor
prefix, update the ug3105 properties accordingly.

The fan curve control patches introduced a regression for at least the
TUF FX506 and possibly other TUF series laptops that do not have support
for fan curve control.
As part of the probing process, asus_wmi_evaluate_method_buf is called
to get the factory default fan curve . The WMI management function
returns 0 on certain laptops to indicate lack of fan curve control
instead of ASUS_WMI_UNSUPPORTED_METHOD. This 0 is transformed to
-ENODATA which results in failure when probing.

Add support for spi bus in serial-multi-instantiate driver
Some peripherals can have either a I2C or a SPI connection
to the host (but not both) but use the same HID for both
types. So it is not possible to use the HID to determine
whether it is I2C or SPI. The driver must check the node
to see if it contains I2cSerialBus or SpiSerialBus entries.
For backwards-compatibility with the existing nodes I2C is
checked first and if such entries are found ONLY I2C devices
are created. Since some existing nodes that were already
handled by this driver could also contain unrelated
SpiSerialBus nodes that were previously ignored, and this
preserves that behavior. If there is ever a need to handle
a node where both I2C and SPI devices must be instantiated
this can be added in future.

The call sequence suggested that misc_device /dev file can be opened
before misc device is yet to be registered, which is done only once.
Here punit_misc_dev_lock was used as common lock, to protect the
registration by multiple ISST HW drivers, one time setup, prevent
duplicate registry of misc device and prevent load/unload when device
is open.
We can split into locks:
- One which just prevent duplicate call to misc_register() and one
time setup. Also never call again if the misc_register() failed or
required one time setup is failed. This lock is not shared with
any misc device callbacks.
- The other lock protects registry, load and unload of HW drivers.
Sequence in isst_if_cdev_register()
- Register callbacks under punit_misc_dev_open_lock
- Call isst_misc_reg() which registers misc_device on the first
registry which is under punit_misc_dev_reg_lock, which is not
shared with callbacks.

The driver as originally submitted accidentally relied on Android having
run before and Android having unmasked the 2nd level IRQ-mask for the
charger IRQ. This worked since these are PMIC registers which are only
reset when the battery is fully drained or disconnected.
Fix the charger IRQ no longer working after loss of battery power by
properly setting the 2nd level IRQ-mask for the charger IRQ.
Note this removes the need to enable/disable our parent IRQ which just
sets the mask bit in the 1st level IRQ-mask register, setting one of
the 2 level masks is enough to stop the IRQ from getting reported.

Add an init() callback to struct x86_dev_info, board descriptions can use
this to do some custom setup before registering the i2c_clients, platform-
devices and servdevs.
Also add an exit() callback to also allow for cleanup of the custom setup.

Some of the broken DSDTs on these devices often also include broken / wrong
_AEI (ACPI Event Interrupt) handlers, which can cause e.g. interrupt storms
by listening to a floating GPIO pin.
Add support for disabling these and disable them on the Asus ME176C and
TF103C tablets.

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.

* tag 'trace-v5.17-3' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace:
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.

Usage: perf stat [<options>] [<command>]
-e, --event <event>event selector. use 'perf list' to list available events
To support, add an extra PMU event symbol type for "baz", and add a new

A previous patch preventing "attr->sample_period" values from being
overridden in pfm events changed a related behaviour in arm-spe.
Before said patch:
perf record -c 10000 -e arm_spe_0// -- sleep 1
Would yield an SPE event with period=10000. After the patch, the period
in "-c 10000" was being ignored because the arm-spe code initializes
sample_period to a non-zero value.
This patch restores the previous behaviour for non-libpfm4 events.
