mac80211: ath10k: search DT for BDF variant info
Board Data File (BDF) is loaded upon driver boot-up procedure. The right board data file is identified on QCA4019 using bus, bmi-chip-id and bmi-board-id. The problem, however, can occur when the (default) board data file cannot fulfill the vendor requirements and it is necessary to use a different board data file. This problem was solved for SMBIOS by adding a special SMBIOS type 0xF8. Something similar has to be provided for systems without SMBIOS but with device trees. No solution was specified by QCA and therefore a new one has to be found for ath10k. The device tree requires addition strings to define the variant name wifi@a000000 { status = "okay"; qcom,ath10k-calibration-variant = "RT-AC58U"; }; wifi@a800000 { status = "okay"; qcom,ath10k-calibration-variant = "RT-AC58U"; }; This would create the boarddata identifiers for the board-2.bin search * bus=ahb,bmi-chip-id=0,bmi-board-id=16,variant=RT-AC58U * bus=ahb,bmi-chip-id=0,bmi-board-id=17,variant=RT-AC58U Signed-off-by: Sven Eckelmann <sven.eckelmann@open-mesh.com>
