2019-10-22AUTHORS: Move src/drivers/[a*-i*] copyrights into AUTHORS fileMartin Roth
As discussed on the mailing list and voted upon, the coreboot project is going to move the majority of copyrights out of the headers and into an AUTHORS file. This will happen a bit at a time, as we'll be unifying license headers at the same time. Updated Authors file is in a separate commit.

2019-07-13drivers/wifi: Add generic WiFi driverKarthikeyan Ramasubramanian
Add generic WiFi driver to support common device operations across multiple types of WiFi controller. BUG=None BRANCH=None TEST=Boot to ChromeOS. Ensure that the SSDT table contains SAR tables and wakeup GPE information. Ensure that the SSDT table is same after the change.

2018-07-13intel/wifi: Add WGDS ACPI method for Geo Aware SARPratik Prajapati
To comply with all relevant bodies throughout the world, SAR settings take into account the lowest common denominator Tx power settings. This setup may lead to non-optimal performance when the user location is in a country that may allow higher power setting. The purpose of Wireless Geo Delta Settings (WGDS) is to provide offset settings for FCC, Europe, Japan and Rest of the world. These offsets would be added (by Intel wifi driver) to the base SAR Tx Power as defined in WRDS and EWRD BUG=b:65155728 BRANCH=none TEST=WGDS ACPI table gets created as expected.

2017-01-13intel/wifi: Create ACPI objects for wifi SAR configurationRobbie Zhang
To support intel wifi SAR configuration, it is required coreboot to publish two ACPI objects (WRDS and EWRD) to supply SAR limit data sets. VPD entry "wifi_sar" is required to supply the raw SAR limit data. BUG=chrome-os-partner:60821 TEST=Enable USE_SAR, boot reef to OS, create the VPD entry, reboot, check the SSDT dump and verify WRDS and EWRD structures.

2016-06-02drivers/intel/wifi: Add support for generating SSDT tableDuncan Laurie
Intel WiFi devices that support wake-on-wifi need to declare a Power Resource for this wake pin. Typically this has been done with a static declaration in the DSDT for each mainboard. By adding it to the existing intel/wifi driver it can be done based on a configuration register in the devicetree. Additionally the WiFi regulatory domain can be set in the SSDT directly instead of needing to use NVS to pass the value to the DSDT. Also add device IDs for Wilkins Peak 2 and Stone Peak 2 devices that are found on Chromebooks, and clean up a long line and some comment formatting. This was tested by booting on an HP Chromebook 13 device and comparing that the output in the SSDT matches what used to be in the DSDT. The WRDD value is read from VPD, if present, not from devicetree.cb. Additionally the case where CONFIG_DRIVERS_INTEL_WIFI is enabled but the wifi device is not described in devicetree.cb is tested to ensure it still generates the AML but does not include the _PRW wake pin. Example: devicetree.cb: device pci 1c.0 on chip drivers/intel/wifi register "wake" = "GPE0_DW0_16" device pci 00.0 on end end end VPD: "region"="us" SSDT.dsl: Scope (\_SB.PCI0.RP01) { Device (WIFI) { Name (_UID, Zero) Name (_DDN, "Intel WiFi") Name (_ADR, 0x00000000) Name (_PRW, Package () { 16, 3 }) Name (WRDD, Package () { Zero, Package () { 0x00000007, 0x00004150 } }) } } Change-Id: I8b5c916f1a04742507dc1ecc9a20c19d3822b18c Signed-off-by: Duncan Laurie <dlaurie@chromium.org> Reviewed-on: https://review.coreboot.org/15019 Tested-by: build bot (Jenkins) Reviewed-by: Aaron Durbin <adurbin@chromium.org>
