[Impact]

 Power button or other wake up sources connected to GPIO
 may not wake up idle AMD systems.

[Fix]

 Enable and disable power management wakeup mode, which is disabled by
 default, accordingly

 The patch series can be found @ https://lore.kernel.org/linux-gpio/20210831120613.1514899-1-Basavaraj.Natikar@amd.com/

[Test]

 This is requested by AMD.

[Where problems could occur]

 Only AMD systems that require GPIOs as wake sources will be affected, i.e.
 amd_gpio_irq_set_wake with "on != 0", but this is intended behaviour.

Basavaraj Natikar (2):
  pinctrl: amd: Add irq field data
  pinctrl: amd: Handle wake-up interrupt
