[ Upstream commit 57d2dbf710d832841872fb15ebb79429cab90fae ]
The GPD win and its sibling the GPD pocket (99% the same electronics in a
different case) use a PCI wifi card. But the ACPI tables on both variants
contain a bug where the SDIO MMC controller for SDIO wifi cards is enabled
despite this. This SDIO MMC controller has a PCI0.SDHB.BRC1 child-device
which _PS3 method sets a GPIO causing the PCI wifi card to turn off.
At the moment there is a pretty ugly kludge in the sdhci-acpi.c code,
just to work around the bug in the DSDT of this single design. This can
be solved cleaner/simply with a quirk overriding the _STA return of the
broken PCI0.SDHB.BRC1 PCI0.SDHB.BRC1 child with a status value of 0,
so that its power_manageable flag gets cleared, avoiding this problem.
Note that even though it is not used, the _STA method for the MMC
controller is deliberately not overridden. If the status of the MMC
controller were forced to 0 it would never get suspended, which would
cause these mini-laptops to not reach S0i3 level when suspended.

Not all ACPI-devices have a HID + UID, allow specifying quirks for
acpi_device_override_status() by path too.
Note this moves the path/HID+UID check to after the CPU + DMI checks
since the path lookup is somewhat costly.
This way this lookup is only done on devices where the other checks
match.

[ Upstream commit 1a68b346a2c9969c05e80a3b99a9ab160b5655c0 ]
Currently, acpi_bus_get_status() calls acpi_device_always_present() to
allow platform quirks to override the _STA return to report that a
device is present (status = ACPI_STA_DEFAULT) independent of the _STA
return.
In some cases it might also be useful to have the opposite functionality
and have a platform quirk which marks a device as not present (status = 0)
to work around ACPI table bugs.
Change acpi_device_always_present() into a more generic
acpi_device_override_status() function to allow this.

[ Upstream commit d431dfb764b145369be820fcdfd50f2159b9bbc2 ]
It turns out that there is a WMI object which controls the PWM2 device
used for the keyboard backlight and that WMI object also provides some
other useful functionality.
The upcoming lenovo-yogabook-wmi driver will offer both backlight
control and the other functionality, so there no longer is a need
to have the lpss-pwm driver binding to PWM2 for backlight control;
and this is now actually undesirable because this will cause both
the WMI code and the lpss-pwm driver to poke at the same PWM
controller.
Drop the always-present quirk for the PWM2 ACPI-device, so that the
lpss-pwm controller will no longer bind to it.

Recently produced GPD win devices have a new BIOS, research into the
changes in this BIOS has found a ChangeLog which shows that the disabling
of the KIOX000A node has been done starting with the 20170221 version.
Unfortunately the GPD pocket uses the exact same DMI strings as the win
and its BIOS was copy-pasted from the GPD win, so it has a disabled
KIOX000A node which we should not enable, so we need to check for the
exact BIOS date.
This commit adds 2 extra entries to the always_present_ids quirk table
with bios_date matches for the older also affected and the latest BIOS.

The _STA method of the Venue 11 Pro 7130 touchscreen has this ugliness:
Method (_STA, 0, NotSerialized) // _STA: Status
{
If ((SDS1 & One) == One)
{
If (RST1 == Zero)
{
Return (0x0F)
}
ElseIf (RST2 == Zero)
{
RST2 = One
TMRV = Timer
}
Else
{
Local0 = ((Timer - TMRV) / 0x2710)
If (Local0 > TMRI)
{
RST2 = Zero
RST1 = Zero
}
}
}
Else
{
Return (Zero)
}
}
Whereby RST1 gets set by _SB.PCI0.GFX0.LCD.LCD1._ON, this means that
after RST1 has been set first _STA must be called to set TIMER and
then after enough time has elapsed _STA must be called twice more, once
to clear RST1 and once to finally return 0xf before the touchscreen will
show up. Which is just crazy.
This commit adds an always_present_ids entry for the SYNA7500 touchscreen
ACPI node, together with a DMI match for the Venue 11 Pro 7130, fixing the
touchscreen not working on this device.

On some x86 systems the DSDT hides APCI devices to work around Windows
driver bugs. On one such system the device is even hidden until a certain
time after _SB.PCI0.GFX0.LCD.LCD1._ON gets called has passed *and*
_STA has been called at least 3 times since. TL;DR: it is a mess.
Until now the always_present_id matching was used to force status
for a whole class of devices, e.g. always enable PWM1 on CHerry Trail
devices.
This commit extends the always_present_id matching code to optionally
also check for a DMI match so that we can also add system specific
quirks to the always_present_id array.

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.
