Subject: [PATCH RFC 0/4] wifi: ath10k: support board-specific firmware overrides
Date: Tue, 30 Jan 2024 18:38:36 +0200 [thread overview]
Message-ID: <20240130-wcn3990-firmware-path-v1-0-826b93202964@linaro.org> (raw)
On WCN3990 platforms actual firmware, wlanmdsp.mbn, is sideloaded to the
modem DSP via the TQFTPserv. These MBN files are signed by the device
vendor, can only be used with the particular SoC or device.
Unfortunately different firmware versions come with different features.
For example firmware for SDM845 doesn't use single-chan-info-per-channel
feature, while firmware for QRB2210 / QRB4210 requires that feature.
Allow board DT files to override the subdir of the fw dir used to lookup
the firmware-N.bin file decribing corresponding WiFi firmware.
For example, adding firmware-name = "qrb4210" property will make the
driver look for the firmware-N.bin first in ath10k/WCN3990/hw1.0/qrb4210
directory and then fallback to the default ath10k/WCN3990/hw1.0 dir.
