On some Cherry Trail systems the GPU ACPI fwnode has power-resources which
point to the PMIC, which is connected over a LPSS I2C controller.

We add a device-link to make sure that the I2C controller is resumed before
the GPU is. But the pci-core changes the power-state of PCI devices from
D3 to D0 at noirq time (to restore the PCI config registers) and before
this commit we were bringing up the I2C controllers from a resume_early
handler which runs later. More specifically the pm-core will first run
all resume_noirq handlers in order and then all resume_early handlers.

So we must not only make sure that the handlers are run in the right order,
but also that the resume of the I2C controller is done at noirq time.

The behavior before this commit, resuming the I2C controller from a
resume_early handler leads to the following errors:

 i2c_designware 808622C1:06: controller timed out
 ACPI Error: AE_ERROR, Returned by Handler for [UserDefinedRegion]
 ACPI Error: Method parse/execution failed \_SB.P18W._ON, AE_ERROR
 video LNXVIDEO:00: Failed to change power state to D0

This commit changes the acpi_lpss.c code to resume the BYT/CHT I2C
controllers at resume_noirq time fixing this.

On some Bay Trail systems the GPU ACPI fwnode has power-resources which
point to the PMIC, which is connected over the LPSS I2C5 controller.

This one was quite nasty to debug, unlike on CHT where the same problem
leads to errors like these:

     i2c_designware 808622C1:06: controller timed out
     ACPI Error: AE_ERROR, Returned by Handler for [UserDefinedRegion]
     ACPI Error: Method parse/execution failed \_SB.P18W._ON, AE_ERROR
     video LNXVIDEO:00: Failed to change power state to D0

On BYT the read-modify-write done by drivers/acpi/pmic/intel_pmic_xpower.c
on the AXP288 PMIC register to change the power-resource state *seems* to
succeed.

But in reality, because the I2C controller has not been resumed yet, the
read silently fails and returns the wrong value, where as the write does
succeed, writing back the wrong value for all the other power-resources
in the same register, turning off a bunch of them. Which of course does
not end well.

This commit adds a RPM consumer link from the GPU (which has a LNXVIDEO
HID) to the BYT LPSS I2C5 controller, so that the I2C controller gets
resumed before the GPU is resumed and thus before we try to change the
power-resource.

lpss_iosf_enter_d3_state() checks if all hw-blocks using the DMA
controllers are in d3 before powering down the DMA controllers.

But on devices, where the I2C bus connected to the PMIC is shared by
the PUNIT, the controller for that bus will never reach d3 since it has
an effectively empty _PS3 method. Instead it appears to automatically
power-down during S0i3 and we never see it as being in d3.

This causes the DMA controllers to never be powered-down on these devices,
causing them to never reach S0i3. This commit uses the ACPI _SEM method
to detect if an I2C bus is shared with the PUNIT and if it is, it removes
it from the mask of devices which lpss_iosf_enter_d3_state() checks for.

This fixes these devices never reaching any S0ix states.

Bay and Cherry Trail DSTDs represent a different set of devices depending
on which OS the device think it is booting. One set of decices for Windows
and another set of devices for Android which targets the Android-x86 Linux
kernel fork (which e.g. used to have its own display driver instead of
using the i915 driver).

Which set of devices we are actually going to get is out of our control,
this is controlled by the ACPI OSID variable, which gets either set through
an EFI setup option, or sometimes is autodetected. So we need to support
both.

This commit adds support for the 80862286 and 808622C0 ACPI HIDs which we

Commit 12864ff8 (ACPI / LPSS: Avoid PM quirks on suspend and resume

for S3/S4 in acpi_lpss_suspend(), and check that flag in

But this overlooks the boot case where acpi_lpss_resume() may get called
without a corresponding acpi_lpss_suspend() having been called.

Thus force setting the flag during boot.

Calling dmi_check_system() early only works on X86. Other
architectures initialize the DMI subsystem later so it's not
ready yet when ACPI itself gets initialized.

In the best case it results in a useless call to a function which
will do nothing. But depending on the dmi implementation, it could
also result in warnings. Best is to not call the function when it
can't work and isn't needed.

Additionally, if anyone ever needs to add non-x86 quirks, it would
surprisingly not work, so document the limitation to avoid confusion.

This is unnecessary and triggers a warning in the hypervisor.

Often systems have more processor entries in their ACPI tables than are
actually installed/active. The ACPI_STA_DEVICE_PRESENT bit cannot be
reliably used, but the ACPI_MADT_ENABLED bit can. In order to not
introduce new functions in the main ACPI processor driver code, simply
use acpi_get_phys_id(), which does more than we need, but which checks
the MADT enabled bit in the process. Any CPU for which we can't
determine the APIC ID is unlikely to work properly anyway, so the extra
checks done by acpi_get_phys_id() should do no harm.

Commit fa85015c (ACPICA: Clear status of all events when entering

ACPI events when entering S5 to fix a functional regression reported
against commit 18996f2d (ACPICA: Events: Stop unconditionally
clearing ACPI IRQs during suspend/resume).  However, it is reported
now that the regression also affects system states other than S5 on
some systems and causes them to wake up from sleep prematurely.

For this reason, make the code in question clear the status of all
ACPI events when entering all sleep states (in addition to S5) to
avoid the premature wakeups (this may cause some wakeup events to
be missed in theory, but the likelihood of that is small and the
change here simply restores the previous behavior of the code).

This commit adds a list of HIDs of devices, which need multiple i2c-clients
instantiated from a single fwnode, to acpi_device_enumeration_by_parent and
makes acpi_device_enumeration_by_parent return false for these devices so
that a platform device will be instantiated.

This allows the drivers/platform/x86/i2c-multi-instantiate.c driver, which

Since commit 63347db0 "ACPI / scan: Use acpi_bus_get_status() to
initialize ACPI_TYPE_DEVICE devs" the status field of normal acpi_devices
gets set to 0 by acpi_bus_type_and_status() and filled with its actual
value later when acpi_add_single_object() calls acpi_bus_get_status().

This means that any acpi_match_device_ids() calls in between will always
fail with -ENOENT.

We already have a workaround for this, which temporary forces status to
ACPI_STA_DEFAULT in drivers/acpi/x86/utils.c: acpi_device_always_present()
and the next commit in this series adds another acpi_match_device_ids()
call between status being initialized as 0 and the acpi_bus_get_status()
call.

Rather then adding another workaround, this commit makes
acpi_bus_type_and_status() initialize status to ACPI_STA_DEFAULT, this is
safe to do as the only code looking at status between the initialization
and the acpi_bus_get_status() call is those acpi_match_device_ids() calls.

Note this does mean that we need to (re)set status to 0 in case the
acpi_bus_get_status() call fails.

If both _DMA and an address size limit are present, we would always
expect the former to be a more specific subset of the latter (since it
