[PATCH v2 0/4] Apple SPI properties

[Lukas Wunner <lukas@wunner.de>]

Retrieve device properties on Macs with an Apple-specific _DSM and
use them in lieu of _CRS data upon SPI slave initialization, v2.

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

The series has now been tested successfully by Ronald.

Changes v1 -> v2:

Patch 2:
- Rebase on uuid-types branch. (Andy, Rafael)
- Don't align assignments. (Mika)
- Move IS_ENABLED() and dmi_match() conditionals into callee. (Mika)
- Tone down messages indicating an unsupported properties version or
  illegal property type to KERN_INFO to avoid scaring or annoying users
  who may see it on every boot despite "quiet", but still allowing
  diagnosis of issues that may ensue. (Mika)

Patch 3:
- Newly inserted patch in v2 to fix an enumeration issue. (Ronald)

Patch 4 (was patch 3 in v1):
- Move IS_ENABLED() and dmi_match() conditionals into callee. (Mika)
- Allow acpi_spi_parse_apple_properties() to augment or override _CRS
  by calling it unconditionally rather than only if _CRS is empty.

Thanks,

Lukas
