From: Andreas Noever <andreas.noever@xxxxxxxxx> This is a resend of Matthew's patches from https://lkml.org/lkml/2014/6/1/165 which are needed to fully support Thunderbolt on Apple hardware: > Apple hardware behaves differently depending on whether or not the OS claims > to be Darwin. Failing to report Darwin results in some hardware being > disabled. However, claiming to be Darwin also alters the behaviour of > battery reporting and PCI handling. These patches add support for reporting > Darwin support and fixing up the behavioural quirks that are exposed as a > result. Without these patches the firmware will cut power to the controller after suspend (at the latest) and the thunderbolt driver will fail. I have reordered them such that the two battery fixes/quirks come before the _OSI change that breaks battery reporting. I have also merged "ACPI: Don't call PCI OSC on Apple hardware when claiming to be Darwin" into "ACPI: Support _OSI("Darwin") correctly" to avoid (temporarily) breaking hotplug events and modified the patch to not touch ACPICA, as requested by Rafael.
