[PATCH 01/53] ACPICA: Change path's type from u8* to char*

[Lv Zheng]

From: Erik Schmauss <erik.schmauss@intel.com>

ACPICA commit 51e73c1d35dd21cfe39277b3c71decd3268f669c

All instances using a named parseOp's path field has a type
cast from u8* to char*. Changing path's type from u8*
to char* eliminates type casting and retains the previous
behavior.

ACPICA commit 3c36625deffdfb034378b1793e2ead9c8fdd767e

Changes the resource descriptor parse tree walk to a general
preprocessing walk and calls the Switch conversion code from here.
Move Switch code to new dmswitch.c file. Also improves algorithm to
handle multiple levels of Switch statements and perform legacy
disassembly for older or otherwise non-spec compliant Switch
implementations.

[PATCH 21/53] ACPICA: ACPI 6.2: Add support for PinFunction() resource

[Lv Zheng]

From: Mika Westerberg <mika.westerberg@linux.intel.com>

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.

[PATCH 22/53] ACPICA: ACPI 6.2: Add support for PinConfig() resource

[Lv Zheng]

From: Mika Westerberg <mika.westerberg@linux.intel.com>

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).

[PATCH 23/53] ACPICA: ACPI 6.2: Add support for PinGroup() resource

[Lv Zheng]

From: Mika Westerberg <mika.westerberg@linux.intel.com>

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.

[PATCH 24/53] ACPICA: ACPI 6.2: Add support for PinGroupFunction() resource

[Lv Zheng]

From: Mika Westerberg <mika.westerberg@linux.intel.com>

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.

[PATCH 25/53] ACPICA: ACPI 6.2: Add support for PinGroupConfig() resource

[Lv Zheng]

From: Mika Westerberg <mika.westerberg@linux.intel.com>

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.

[PATCH 26/53] ACPICA: Fix a type value overlap in the AML support file

[Lv Zheng]

From: Bob Moore <robert.moore@intel.com>

ACPICA commit 7cb6e66982178bbc96a6f1f7969da95e9da753fa

An AML opcode type field was overlapped with values used
for the top-level dispatch. Did not cause an actual problem,
but fixed anyway.

[PATCH 27/53] ACPICA: Core: Always set GPIO VendorOffset

[Lv Zheng]

From: Mika Westerberg <mika.westerberg@linux.intel.com>

ACPICA commit 51a92f414de7af1f7f7524de3f61daf5413cac9f

Acpiexec gives this warning when resources containing GPIOs are extracted
using Resource command:

  **** Data mismatch in descriptor [00] type 8C, Offset 00000000 ****
  Mismatch at byte offset 13: is 00, should be 25
  **** Data mismatch in descriptor [01] type 8C, Offset 00000025 ****
  Mismatch at byte offset 13: is 00, should be 25

This happens because we do not set VendorOffset when doing resource to AML
conversion. Fix this by always setting VendorOffset.

[PATCH 28/53] ACPICA: OSL: Add support to exclude stdarg.h

[Lv Zheng]

ACPICA commit e2df7455a9a4301b03668e4c9c02c7a564cc841c

Some hosts may choose not to include stdarg.h, implementing a
configurability in acgcc.h, allowing OSen like Solaris to exclude stdarg.h.
This patch also fixes acintel.h accordingly without providing builtin
support as Intel compiler is similar as GCC. Reported by Dana Myers, fixed
by Lv Zheng.

[PATCH 31/53] ACPICA: Explicitly cast 1 to u32

From: Erik Schmauss <erik.schmauss@intel.com>

ACPICA commit 4091360d6526c8d4f1e6bccb6b1c3123bda9ac33

The runtime errors caused when acpica tools are compiled with
-fsanitize=shift imply that these 1s are stored in integers.
This cast insures that 1 is stored in unsigned integers.

[PATCH 33/53] ACPICA: Dispatcher: Remove unnecessary call to debugger

[Lv Zheng]

ACPICA commit eaa455accf165fee2df26410e271aab162264f6c

UBSAN reports an index out of range use in dsutils.c.
  acpi_db_display_argument_object(
  	walk_state->operands[walk_state->num_operands - 1],
  	                     ^^^^^^^^^^^^^^^^^^^^^^^^^^^^
  	walk_state);

This call was simply wrong, generated redundant debugger messages, and
resulted in a -1 index into the operand stack. Linux kernel bug #120351
(link #1) and #194845 (link #2).

Originally fixed by Navin P.S. (link #1, comment 8), refined by Lv Zheng
(link #3).

[PATCH 34/53] ACPICA: Disassembler: Abort on an invalid/unknown AML opcode

[Lv Zheng]

From: Bob Moore <robert.moore@intel.com>

ACPICA commit ed0389cb11a61e63c568ac1f67948fc6a7bd1aeb

An invalid opcode indicates something seriously wrong with the
input AML file. The AML parser is immediately confused and lost,
causing the resulting parse tree to be ill-formed. The actual
disassembly can then cause numerous unrelated errors and faults.

This change aborts the disassembly upon discovery of such an
opcode during the AML parse phase.

[PATCH 38/53] ACPICA: Split resource descriptor decode strings to a new file

[Lv Zheng]

From: Bob Moore <robert.moore@intel.com>

ACPICA commit 00906ae0aff4c6b76abc232ef99700e7d7c0e325

There are enough of these strings to justify a separate file.
Also, these strings are only used for the disassembler and
the debugger. Thus, this change improves ACPICA modularity.

[PATCH 41/53] ACPICA: Fix for Device/Thermal objects with ObjectType and DerefOf

[Lv Zheng]

From: Bob Moore <robert.moore@intel.com>

ACPICA commit 89565151aa4db7b546d4935b187bf2c4a86885ee

These types must be special cased because the namespace node
does not contain a subobject as do all other types.

From: Erik Schmauss <erik.schmauss@intel.com>

ACPICA commit 0d5dd42fd7d5129835b6d92250378a962eb73cb3

This is done so that the aml parser will build the parse tree of
External Op as a named object. This is done to streamline creation
of external op parse nodes and facilitate namespace resolution of
externals.

[Lv Zheng]

From: Erik Schmauss <erik.schmauss@intel.com>

ACPICA commit c512c2bfcce65b8e8f37d549ac2fa4a1e0182e46

Since Externals could be of ACPI_TYPE_METHOD, there is a possibility
that the acpi_ns_lookup may cause a new scope to be opened. Therefore,
disable opening the scope for all acpi_ns_lookup invocations that deal
with externals.

From: Erik Schmauss <erik.schmauss@intel.com>

ACPICA commit 117be4819588df3b7146f6f01723639b1d61e775

By doing so, external control method resolutions can be resolved like
normal control methods. This eliminates the need to reparse the aml
all over again for external control methods that were encoded within
the aml with the 0x15 bytecode.

From: Erik Schmauss <erik.schmauss@intel.com>

ACPICA commit 0ed9f2e2ccc112439eaa355b5952a05d6fdb7814

An external declaration is a conflicting declaration when a name has
been declared as an external and a named object within the same file.
