[PATCH V6 0/8] vfio, platform: add ACPI support

[Sinan Kaya]

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 from V5:
1. Handle reset function call failures in open and release (new patch).
2. Bring out extra debug information when failure happens (new patch).
3. Address review comments from Eric in ACPI _RST patch.

Sinan Kaya (8):
  vfio: platform: move reset call to a common function
  vfio: platform: determine reset capability
  vfio: platform: add support for ACPI probe
  vfio: platform: add extra debug info argument to call reset
  vfio: platform: call _RST method when using ACPI
  vfio, platform: make reset driver a requirement by default
  vfio: platform: check reset call return code during open
  vfio: platform: check reset call return code during release
