[PATCH V5 0/6] vfio, platform: add ACPI support

The device tree code checks for the presence of a reset driver and calls
the of_reset function pointer by looking up the reset driver as a module.

ACPI defines _RST method to perform device level reset. After the _RST
method is executed, the OS can resume using the device.

This patch checks the presence of _RST method and calls the _RST
method when reset is requested.

Changes:
1. No functional changes. Just divide the patches into subpatches for easy
review.

Sinan Kaya (6):
  vfio: platform: rename reset function
  vfio: platform: move reset call to a common function
  vfio: platform: determine reset capability
  vfio: platform: add support for ACPI probe
  vfio: platform: call _RST method when using ACPI
  vfio, platform: make reset driver a requirement by default
