Subject: [PATCH v4 0/5] Apple SPI properties

Retrieve device properties on Macs with an Apple-specific _DSM and
use them in lieu of _CRS data upon SPI slave initialization
in preparation of supporting the SPI keyboard on 2015+ MacBooks, v4.

Please refer to the cover letter of v1 for further details:
http://www.spinics.net/lists/linux-acpi/msg75537.html

Changes v3 -> v4:

Patch 1:
- Extend consolidation of Apple DMI checks to the entire tree
  instead of just the ACPI core. (Rafael, Andy, Darren)

Patches 2 - 5 are as before.

Thanks,

Lukas


Lukas Wunner (5):
  treewide: Consolidate Apple DMI checks
  ACPI / property: Don't evaluate objects for devices w/o handle
  ACPI / property: Support Apple _DSM properties
  ACPI / scan: Recognize Apple SPI and I2C slaves
  spi: Use Apple device properties in absence of ACPI resources
