[PATCH v4 0/3] ACPI: Add irq_type to gpio interrupt

[Christophe Ricard <christophe.ricard@xxxxxxxxx>]

Hi,

ACPI probing method does not retrieve irq_type from a gpio interrupt declared
with GpioInt as it is done with devicetree probing. In other terms, irq_get_trigger_type
will always send back 0.

Those 3 patches propose a way to retrieve the correct interrupt polarity/type from a GpioInt
acpi declaration when using irq_get_trigger_type.

Since v3:
- A new fied irq_type in acpi_gpio_info is added and the way the irq_type is attached to the irq is improved.
- The irq described in the acpi spi slave node is now set 

Best Regards
Christophe 

Christophe Ricard (3):
  acpi: Rename acpi_gsi_get_irq_type to acpi_get_irq_type and export
    symbol
  ACPI / gpio: Add irq_type when a gpio is used as an interrupt
  ACPI / spi: attach gpio irq from acpi description to spi device
