Since I've been doing a lot of work on Linux Bay Trail / Cherry Trail support, I've gathered a collection of ACPI DSDTs from about 50 such machines. Looking at these DSTDs many have an ACPI device entry describing a bcm bluetooth device (often disabled in the DSDT), quite a few of these ACPI device entries have a resource-table where the order does not match with the order currently associated with the HID of that entry in the bcm_acpi_match table. Looking at the Windows .inf files, there is nothing indicating a specific order there, so I believe that there is no 1:1 mapping between the ACPI HID and the order in which the resources are listed. Therefor this commit replaces the hardcoded mapping based on ACPI HID, with code which actually checks in which order the resources are listed and bases the gpio-mapping on that. This should ensure that we always pick the right mapping and this will make adding new ACPI HIDs to the driver easier. This has been tested on the following devices: -Asus T100CHI BCM2E39 / brcmfmac43241b4-sdio / BCM4324B3-37.4M.hcd -Asus T100TA BCM2E39 / brcmfmac43241b4-sdio / BCM4324B3-37.4M.hcd -Asus T200TA BCM2E65 / brcmfmac43340-sdio / BCM43341B0-37.4M.hcd -Jumper ezPad mini 3 BCM2E74 / brcmfmac43430a0-sdio / BCM4343A0-26M.hcd -Acer Iconia Tab8 w1-8 BCM2E83 / brcmfmac4330-sdio / BCM4330B1-26M.hcd -Chuwi Vi8 plus(CWI519) BCM2EAA / brcmfmac43430-sdio / BCM43430A1-26M.hcd Which together cover all 3 combinations of using an Interrupt resource / GpioInt resource as first resource / GpioInt resource as last resource.

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.
