commit 5030fc7d10d63c84f2eb796a451fde6cb5cfb669 Author: Aaron Durbin adurbin@chromium.org Date: Wed Dec 7 17:39:09 2016 -0600
mainboard/google/reef: fill in NHLT ACPI OEM header fields
Fill in the NHLT ACPI OEM header fields to differentiate different audio solutions on a per board basis. This handles boards that share a firmware that are differentiated by the SKU id and boards that have their own firmware. For the latter, the Oem Table ID uses the VARIANT_DIR to differentiate. "reef" is always used for Oem ID which is treated as more of family in this case.
iasl -d shows the following on reef: [00Ah 0010 6] Oem ID : "reef" [010h 0016 8] Oem Table ID : "reef" [018h 0024 4] Oem Revision : 00000008
