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.

2017-01-09chromeos: Implement locating and decoding wifi sar data from VPDRobbie Zhang
A VPD entry "wifi_sar" needs to be created which contains a heximal encoded string in length of 40 bytes. get_wifi_sar_limits() function retrieves and decodes the data from the VPD entry, which would later be consumed by platform code.
