Duncan Laurie b25a45ca46 skylake: Add SD card device to configure card detect GPIO
Add a PCI driver for the skylake SD card device and have it generate
an entry in the SSDT for the card detect GPIO if it is provided by the
mainboard in devicetree.

This sets up a card detect GPIO configuration that will trigger an
interrupt on both edges with a 100ms debounce timeout and can wake the
SD controller from D3 state.

The GpioInt() entry is bound to the "cd-gpio" device property which will
be consumed by the kernel driver.

The resulting ACPI output in the SSDT will be combined with the SDXC
device declaration in the DSDT.

Example:

Scope (\_SB.PCI0.SDXC)
{
  Name (_CRS, ResourceTemplate () {
    GpioInt (Edge, ActiveBoth, SharedAndWake, PullNone, 10000,
             "\\_SB.PCI0.GPIO", 0, ResourceConsumer) { 35 }
  })
  Name (_DSD, Package () {
    ToUUID ("daffd814-6eba-4d8c-8a91-bc9bbf4aa301"),
    Package () {
      Package () { "cd-gpio", Package () { \_SB.PCI0.SDXC, 0, 0, 1 } }
    }
  })
}

Duncan Laurie 559e947306 acpi_device: Add support for writing ACPI Device Properties
The recent ACPI specification extensions have formally defined a
method for describing device information with a key=value format that
is modeled after the Devicetree/DTS format using a special crafted
object named _DSD with a specific UUID for this format.

There are three defined Device Property types: Integers, Strings, and
References.  It is also possible to have arrays of these properties
under one key=value pair.  Strings and References are both represented
as character arrays but result in different generated ACPI OpCodes.

Various helpers are provided for writing the Device Property header
(to fill in the object name and UUID) and footer (to fill in the
property count and device length values) as well as for writing the
different Device Property types.  A specific helper is provided for
writing the defined GPIO binding Device Property that is used to allow
GPIOs to be referred to by name rather than resource index.

This is all documented in the _DSD Device Properties UUID document:
http://uefi.org/sites/default/files/resources/_DSD-device-properties-UUID.pdf

This will be used by device drivers to provide device properties that
are consumed by the operating system.  Devicetree bindings are often
described in the linux kernel at Documentation/devicetree/bindings/

A sample driver here has an input GPIO that it needs to describe to
the kernel driver:

chip.h:
  struct drivers_generic_sample_config {
    struct acpi_gpio mode_gpio;
  };

sample.c:
  static void acpi_fill_ssdt_generator(struct device *dev) {
    struct drivers_generic_sample_config *config = dev->chip_info;
    const char *path = acpi_device_path(dev);
    ...
    acpi_device_write_gpio(&config->mode_gpio);
    ...
    acpi_dp_write_header();
    acpi_dp_write_gpio("mode-gpio", path, 0, 0, 0);
    acpi_dp_write_footer();
    ...
  }

devicetree.cb:
  device pci 1f.0 on
    chip drivers/generic/sample
      register "mode_gpio" = "ACPI_GPIO_INPUT(GPP_B1)"
      device generic 0 on end
    end
  end

Duncan Laurie cfb6ea7e65 acpi_device: Add support for writing ACPI GPIO descriptors
Add definitions to describe GPIOs in generated ACPI objects and a
method to write a GpioIo() or GpioInt() descriptor to the SSDT.

ACPI GPIOs have many possible configuration options and a structure
is created to describe it accurately in ACPI terms.  There are many
shared descriptor fields between GpioIo() and GpioInt() so the same
function can write both types.

GpioInt shares many properties with ACPI Interrupts and the same types
are re-used here where possible.  One addition is that GpioInt can be
configured to trigger on both low and high edge transitions.

One descriptor can describe multiple GPIO pins (limited to 8 in this
implementation) that all share configuration and controller and are
used by the same device scope.

Accurately referring to the GPIO controller that this pin is connected
to requires the SoC/board to implement a function handler for
acpi_gpio_path(), or for the caller to provide this directly as a
string in the acpi_gpio->reference variable.

This will get used by device drivers to describe their resources in
the SSDT.  Here is a sample for a Maxim 98357A I2S codec which has a
GPIO for power and channel selection called "sdmode".

chip.h:
  struct drivers_generic_max98357a_config {
    struct acpi_gpio sdmode_gpio;
  };

max98357a.c:
  void acpi_fill_ssdt_generator(struct device *dev) {
    struct drivers_generic_max98357a_config *config = dev->chip_info;
    ...
    acpi_device_write_gpio(&config->sdmode_gpio);
    ...
  }

devicetree.cb:
  device pci 1f.3 on
    chip drivers/generic/max98357a
      register "sdmode_gpio" = "ACPI_GPIO_OUTPUT(GPP_C5)"
      device generic 0 on end
    end
  end

SSDT.dsl:
  GpioIo (Exclusive, PullDefault, 0, 0, IoRestrictionOutputOnly,
          "\\_SB.PCI0.GPIO", 0, ResourceConsumer, ,) { 53 }

Duncan Laurie 6b7c1f605c acpi_device: Add support for writing ACPI Interrupt descriptors
Add definitions for ACPI device extended interrupts and a method to
write an Interrupt() descriptor to the SSDT output stream.

Interrupts are often tied together with other resources and some
configuration items are shared (though not always compatibly) with
other constructs like GPIOs and GPEs.

These will get used by device drivers to write _CRS sections for
devices into the SSDT.  One usage is to include a "struct acpi_irq"
inside a config struct for a device so it can be initialized based
on settings in devicetree.

Example usage:

chip.h:
  struct drivers_i2c_generic_config {
    struct acpi_irq irq;
  };

generic.c:
  void acpi_fill_ssdt_generator(struct device *dev) {
    struct drivers_i2c_generic_config *config = dev->chip_info;
    ...
    acpi_device_write_interrupt(&config->irq);
    ...
  }

devicetree.cb:
  device pci 15.0 on
    chip drivers/i2c/generic
      register "irq" = "IRQ_EDGE_LOW(GPP_E7_IRQ)"
      device i2c 10 on end
    end
  end

SSDT.dsl:
  Interrupt (ResourceConsumer, Edge, ActiveLow, Exclusive,,,) { 31 }
