Hans de Goede 7a2a6d71ee Bluetooth: hci_bcm: Treat Interrupt ACPI resources as always being active-low 
commit bb5208b314 upstream.

Older devices with a serdev attached bcm bt hci, use an Interrupt ACPI
resource to describe the IRQ (rather then a GpioInt resource).

These device seem to all claim the IRQ is active-high and seem to all need
a DMI quirk to treat it as active-low. Instead simply always assume that
Interrupt resource specified IRQs are always active-low.

This fixes the bt device not being able to wake the host from runtime-
suspend on the: Asus T100TAM, Asus T200TA, Lenovo Yoga2 and the Toshiba
Encore, without the need to add 4 new DMI quirks for these models.

This also allows us to remove 2 DMI quirks for the Asus T100TA and Asus
T100CHI series. Likely the 2 remaining quirks can also be removed but I
could not find a DSDT of these devices to verify this.

README

Linux kernel

This file was moved to Documentation/admin-guide/README.rst

Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF.

In order to build the documentation, use make htmldocs or make pdfdocs.

There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file.

Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
