044b723951 ACPICA: ACPI 6.2: Add support for PinGroupConfig() resource
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.

f8a6c86644 ACPICA: ACPI 6.2: Add support for PinGroupFunction() resource
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.

fdaa098077 ACPICA: ACPI 6.2: Add support for PinGroup() resource
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.

97028ce6fc ACPICA: ACPI 6.2: Add support for PinConfig() resource
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).

2b72693066 ACPICA: ACPI 6.2: Add support for PinFunction() resource
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.

Teach ACPICA about this new resource.

4ac4c5fad8 ACPICA: Headers: Deploy #pragma pack (push) and (pop).
Use push and pop to both guarantee that the correct alignment is used,
and to restore the alignment to whatever it was before the header
was included.

It is reported that the #pragma pack(push/pop) directives are not supported
by the specific GCCs, but this patch still doesn't affect kernel build
as there are already #pragma pack([1]) directives used in the old ACPICA
headers, which means there shouldn't be GCCs that are currently used to
compile the ACPI kernels do not support #pragma pack() directives.

739dcbb90a ACPICA: Cleanup source to reduce differences between Linux and ACPICA.
This is a cosmetic patch only. Comparison of the resulting binary showed
only line number differences.

This patch does not affect the generation of the Linux binary.
This patch decreases 389 lines of 20121018 divergence.diff.

This patch reduces source code diff caused by the simple code maintenance
work:
1. Deletion of the unused include files.
2. Deletion of the deprecated codes blocks.
3. Repositioning of the code blocks.
4. Replacing the values with the well defined macros.
5. Replacing the types with the equivalent types.
