Kai Heng Feng ae976358cd Revert "ACPI / bus: Parse tables as term_list for Dell XPS 9570 and Precision M5530"
Reverts commit 36904703ae (ACPI / bus: Parse tables as term_list
for Dell XPS 9570 and Precision M5530).

Since commit 5a8361f7ec (ACPICA: Integrate package handling with
module-level code), acpi_gbl_execute_tables_as_methods is always
true, so we can remove the quirk for XPS 9570/Precision M5530.

Andy Shevchenko 8ff277c5bf ACPI / bus: Remove checks in acpi_get_match_data()
As well as its sibling of_device_get_match_data() has no such checks,
no need to do it in acpi_get_match_data().

First of all, we are not supposed to call fwnode API like this without
driver attached.

Second, since __acpi_match_device() does check input parameter there is
no need to duplicate it outside.

And last but not least one, the API should still serve the cases when
ACPI device is enumerated via PRP0001. In such case driver has neither
ACPI table nor driver data there.

Andy Shevchenko 4222f38ca3 ACPI / bus: Do not traverse through non-existed device table
When __acpi_match_device() is called it would be possible to have
ACPI ID table a NULL pointer. To avoid potential dereference,
check for this before traverse.

While here, remove redundant 'else'.

Note, this patch implies a bit of refactoring acpi_of_match_device()
to return pointer to OF ID when matched followed by refactoring
__acpi_match_device() to return either ACPI or OF ID when matches.

Kai Heng Feng 36904703ae ACPI / bus: Parse tables as term_list for Dell XPS 9570 and Precision M5530
The i2c touchpad on Dell XPS 9570 and Precision M5530 doesn't work out
of box.

The touchpad relies on its _INI method to update its _HID value from
XXXX0000 to SYNA2393.

Also, the _STA relies on value of I2CN to report correct status.

Set acpi_gbl_parse_table_as_term_list so the value of I2CN can be
correctly set up, and _INI can get run. The ACPI table in this machine
is designed to get parsed this way.

Also, change the quirk table to a more generic name.

Hans de Goede 54ddce7062 ACPI / bus: Do not call _STA on battery devices with unmet dependencies
The battery code uses acpi_device->dep_unmet to check for unmet deps and
if there are unmet deps it does not bind to the device to avoid errors
about missing OpRegions when calling ACPI methods on the device.

The missing OpRegions when there are unmet deps problem also applies to
the _STA method of some battery devices and calling it too early results
in errors like these:

[    0.123579] ACPI Error: No handler for Region [ECRM] (00000000ba9edc4c)
               [GenericSerialBus] (20170831/evregion-166)

               \_SB.I2C1.BAT1._STA, AE_NOT_EXIST (20170831/psparse-550)

This commit fixes these errors happening when acpi_get_bus_status gets
called by checking dep_unmet for battery devices and reporting a status
of 0 until all dependencies are met.

acpi_str_to_uuid() becomes useless after the conversion and it's safe to

Hans de Goede b7ecf663c7 ACPI / bus: Introduce a list of ids for "always present" devices
Several Bay / Cherry Trail devices (all of which ship with Windows 10) hide
the LPSS PWM controller in ACPI, typically the _STA method looks like this:

    Method (_STA, 0, NotSerialized)  // _STA: Status
    {
        If (OSID == One)
        {
            Return (Zero)
        }

        Return (0x0F)
    }

Where OSID is some dark magic seen in all Cherry Trail ACPI tables making
the machine behave differently depending on which OS it *thinks* it is
booting, this gets set in a number of ways which we cannot control, on
some newer machines it simple hardcoded to "One" aka win10.

This causes the PWM controller to get hidden, which means Linux cannot
control the backlight level on cht based tablets / laptops.

Since loading the driver for this does no harm (the only in kernel user
of it is the i915 driver, which will only uses it when it needs it), this
commit makes acpi_bus_get_status() always set status to ACPI_STA_DEFAULT
for the LPSS PWM device, fixing the lack of backlight control.

Dou Liyang c962cff17d Revert "x86/acpi: Set persistent cpuid <-> nodeid mapping when booting"
Revert: dc6db24d24 ("x86/acpi: Set persistent cpuid <-> nodeid mapping when booting")

The mapping of "cpuid <-> nodeid" is established at boot time via ACPI
tables to keep associations of workqueues and other node related items
consistent across cpu hotplug.

But, ACPI tables are unreliable and failures with that boot time mapping
have been reported on machines where the ACPI table and the physical
information which is retrieved at actual hotplug is inconsistent.

Revert the mapping implementation so it can be replaced with a less error
prone approach.

It has no effect on non-TBM3 CPUs.
