[PATCH V6 3/7] device property: Introduce a common API to fetch device match data
From: Sinan Kaya <hidden>
Date: 2017-12-05 17:07:27
Also in:
linux-acpi, linux-arm-msm, linux-devicetree, lkml
Subsystem:
acpi, driver core, kobjects, debugfs and sysfs, software nodes and device properties, the rest · Maintainers:
"Rafael J. Wysocki", Greg Kroah-Hartman, Danilo Krummrich, Linus Torvalds
There is an OF/ACPI function to obtain the driver data. We want to hide OF/ACPI details from the device drivers and abstract following the device family of functions.
