[PATCH v4 0/5] Apple SPI properties
From: Lukas Wunner
Date: Tue Aug 01 2017 - 08:10:51 EST
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
