ACPICA commit 08b83591c0db751769d61fa889f4f50f575aeffb
PinGroupConfig() is analogous to PinGroupFunction() but instead of mode
(muxing), it is used to apply specific fine-grained configuration to a
set of referenced pins.
The format of this new resource is:
PinGroupConfig (Shared/Exclusive, PinConfigType, PinConfigValue,
ResourceSource, ResourceSourceIndex, ResourceSourceLabel,
ResourceUsage, DescriptorName, VendorData)
The PinConfigType/PinConfigValue are the same used by PinConfig()
resource.
Here also the combination of ResourceSource and ResourceSourceLabel is
used to specify the PinGroup() this resource refers to.

ACPICA commit bd9a745749eac7137cd23085e6bdeb322de14ea2
PinGroupFunction() is a new resource introduced with ACPI 6.2. It is
used with PinGroup() to configure specific mode for a set of pins
exposed by a GPIO controller.
The format of the resource is:
PinGroupFunction (Shared/Exclusive, FunctionNumber, ResourceSource,
ResourceSourceIndex, ResourceSourceLabel,
ResourceUsage, DescriptorName, VendorData)
The resource_source and ResourceSourceLabel fields are used to specify
the PinGroup() resource referenced by PinGroupFunction().
Device (GPIO)
{
Name (_CRS, ResourceTemplate () {
PinGroup ("group1") {2, 3}
PinGroup ("group2") {4, 5}
...
})
}
Device (I2C)
{
Name (_CRS, ResourceTemplate () {
PinGroupFunction (Exclusive, 6, "^GPIO", 0, "mygroup2")
})
}
In the above example the PinGroupFunction() references the second
PinGroup() resource (using label "mygroup2" and configures pins 4 and 5
into mode 6.

ACPICA commit 7d928e3174fb19d7dc0066b03c30bea07c001563
ACPI 6.2 introduced a new resource that is used to declare set of pins
belonging to a GPIO controller. This resource is referenced by new
PinGroupFunction() and PinGroupConfig() resources using ResourceSource
and ResourceLabel fields.
The PinGroup() resource looks like this:
PinGroup (ResourceLabel, ResourceUsage, DescriptorName,
VendorData) {Pin List}
This resource should be listed in _CRS under the GPIO/pincontroller
device providing these pins.

ACPICA commit a06fdba686cefccd5dd5b93b52fa0f1e3f984906
ACPI 6.2 introduced a new resource that is used to specify fine-grained
configuration of a pin or set of pins used by a device. The ASL syntax of
this new resource looks like:
PinConfig (Shared/Exclusive, PinConfigType, PinConfigValue,
ResourceSource, ResourceSourceIndex, ResourceUsage,
DescriptorName, Vendordata) {Pin List}
PinConfigType is an integer with following accepted values:
0x00 (Default) - No configuration is applied to the pin
0x01 (Bias Pull-up) - Pin is pulled up using certain size resistor
0x02 (Bias Pull-down) - Pin is pulled down using certain size resistor
0x03 (Bias Default) - Set to default biasing
0x04 (Bias Disable) - All bias settings will be disabled
0x05 (Bias High Impedance) - Configure the pin as hi_z
0x06 (Bias Bus Hold) - Configure the pin in a weak latch state where
it drives the last value on a tristate bus
0x07 (Drive Open Drain) - Configure the pin into open drain state
0x08 (Drive Open Source) - Configure the pin into open source state
0x09 (Drive Push Pull) - Configure the pin into push-pull state
0x0a (Drive Strength) - How much the pin can supply current
0x0b (Slew Rate) - Configure slew rate of the pin
0x0c (Input Debounce) - Enable input debouncer for the pin
0x0d (Input Schmitt Trigger) - Enable schmitt trigger for the pin
0x0e - 0x7f - Reserved
0x80 - 0xff - Vendor defined types
The PinConfigValue depends on the type and is expressed as units
suitable for that type (for example bias uses Ohms).

ACPICA commit 6bbc6357f7061f1243601adde0ea45f7a89274e0
ACPI 6.2 introduced a new resource that is used to describe how certain
pins are muxed for a device. The ASL syntax of this new resource looks
like below:
PinFunction(Shared, PinConfig, FunctionNumber, ResourceSource,
ResourceSourceIndex, ResourceUsage, DescriptorName,
VendorData) {Pin List}
Which is pretty similar to GpioIo()/GpioInt() resources.

ACPICA commit b2294cae776f5a66a7697414b21949d307e6856f
This patch removes unwanted spaces for typedef. This solution doesn't cover
function types.
Note that the linuxize result of this commit is very giant and should have
many conflicts against the current Linux upstream. Thus it is required to
modify the linuxize result of this commit and the commits around it
manually in order to have them merged to the Linux upstream. Since this is
very costy, we should do this only once, and if we can't ensure to do this
only once, we need to revert the Linux code to the wrong indentation result
before merging the linuxize result of this commit. Lv Zheng.

The loop terminates on a NULL resource pointer, which can never
happen since the loop simply increments a valid resource pointer.
This fix changes the loop to terminate on an end-of-buffer condition.
Problem can be seen by callers to AcpiSetCurrentResources with an
invalid or corrupted resource descriptor; or a resource descriptor
without an END_TAG descriptor.

acpi_rs_get_pci_routing_table_length is not performing sufficient
validation on the package returned from _PRT. It assumes a package of
packages and fails/faults if this is not the case.
We should validate each subpackage when extracted from the parent
package, and not accept objects of the wrong type, since that will just
cause the scanning to fail (likely with a kernel oops).
This can only happen with a serious BIOS bug, and is accompanied by a
warning something like this:
