On some Goldmont based systems such as ASRock J3455M the BIOS may not
enable the IPC1 device that provides access to the PMC and PUNIT. In
such scenarios, the IOSS and PSS resources from the platform device can
not be obtained and result in a invalid telemetry_plt_config which is an
internal data structure that holds platform config and is maintained by
the telemetry platform driver.
This is also applicable to the platforms where the BIOS supports IPC1
device under debug configurations but IPC1 is disabled by user or the
policy.
This change allows user to know the reason for not seeing entries under
/sys/kernel/debug/telemetry/* when there is no apparent failure at boot.

A driver for LG Gram laptop supporting features not available through the
standard interfaces:
- Support for the 5 Fn keys that generate ACPI or WMI events.
- Two software controlled LEDs: keyboard backlight (also controlled by
hardware) and touchpad LED.
- Extra features: reader mode, Fn lock, cooling mode, USB charge mode, and
maximal battery charging level.

The original asus-wmi queues a work which calls the ACPI/WMI methods to
update the keyboard LED brightness. Similar drivers - acer-wmi,
dell-wmi-led just call the ACPI/WMI methods directly without workqueues.
This patch simplifies the keyboard brightness updating process which
calls the kbd_led_update function directly without workqueue in
asus-wmi.

Bay and Cherry Trail devices with a Dollar Cove or Whiskey Cove PMIC
have an ACPI node with a HID of INT33FE which is a "virtual" battery
device implementing a standard ACPI battery interface which depends upon
a proprietary, undocument OpRegion called BMOP. Since we do have docs
for the actual fuel-gauges used on these boards we instead use native
fuel-gauge drivers talking directly to the fuel-gauge ICs on boards which
rely on this INT33FE device for their battery monitoring.
On boards with a Dollar Cove PMIC the INT33FE device's resources (_CRS)
describe a non-existing I2C client at address 0x6b with a bus-speed of
100KHz. This is a problem on some boards since there are actual devices
on that same bus which need a speed of 400KHz to function properly.
This commit adds the INT33FE HID to the list of devices with I2C resources
which should be enumerated as a platform-device rather then letting the
i2c-core instantiate an i2c-client matching the first I2C resource,
so that its bus-speed will not influence the max speed of the I2C bus.
This fixes e.g. the touchscreen not working on the Teclast X98 II Plus.
The INT33FE device on boards with a Whiskey Cove PMIC is somewhat special.
Its first I2C resource is for a secondary I2C address of the PMIC itself,
which is already described in an ACPI device with an INT34D3 HID.
But it has 3 more I2C resources describing 3 other chips for which we do
need to instantiate I2C clients and which need device-connections added
between them for things to work properly. This special case is handled by
the drivers/platform/x86/intel_cht_int33fe.c code.
Before this commit that code was binding to the i2c-client instantiated
for the secondary I2C address of the PMIC, since we now instantiate a
platform device for the INT33FE device instead, this commit also changes
the intel_cht_int33fe driver from an i2c driver to a platform driver.
This also brings the intel_cht_int33fe drv inline with how we instantiate
multiple i2c clients from a single ACPI device in other cases, as done
by the drivers/platform/x86/i2c-multi-instantiate.c code.

Clang warns that mlxplat_mlxcpld_msn201x_items is not going to be

Some users have been reporting issues with thunderbolt being turned off
before fully initialized. This is suspected to be caused by userspace
turning off the Thunderbolt controller using intel-wmi-thunderbolt
prematurely.
Userspace has already made some mitigations for this situation:
https://github.com/hughsie/fwupd/commit/ef6f1d76983c9b66
https://github.com/hughsie/fwupd/commit/c07ce5b4889a5384
To allow easier debugging of this situation add output that can be turned
on with dynamic debugging to better root cause this problem.

There is a table of Vendor/Model/Version {control data} in this driver,
but outside of the initial probe, the V/M/V is never used again, and
neither are any of the entries for platforms other than the one which
matches the running target.
By simply storing the {control data} for the matched platform, we can
mark the large table __initconst, which reduces the loaded driver size
by 20 percent.

As can be seen in the context, the BIOS registers haven't changed in
the previous versions, so the assumption is they won't have changed
in this last update for this somewhat older platform either.

Just like we avoid specifying actual block devices like sda for fdisk
and dd examples, we should not specify specific thermal zones here.
On the platform I was testing on, zone0 was acpitz, and zone1 was for
this acerhdf driver. Make the printk such that it won't work with a
blind cut-and-paste, and force the user to determine which zone is
correct for this driver.

This driver has two module parameters that allow an override of the
checks for matching model and BIOS version. However, both parameters
expect you to choose an entry from the existing list of supported
systems, encoded within the driver itself.
Without the source, such as in a binary distribution, the end user
does not have access to this information, thus rendering the two
module parameters essentially useless.
Add a module parameter that allows the end user to dump the list
of make/model/versions so that they can then pick one that most
closely matches their own system.

Normally, a module parameter for a BIOS check override implies "pretend
you support this version" (and the user will enter their local version).
However, this driver uses the model/BIOS module parameters in a way that
is "pretend my system is the supported model XYZ with BIOS version ABC."
which is less common.
Since the help strings don't make such a distinction, one gets this
somewhat frustrating scenario, where the user sees the error, enters
*their* BIOS version and then gets the same error:
root@gw:~# modprobe acerhdf

Clarify the module param help text to make it clear that the driver
expects a choice from existing supported models/versions.
