I'm looking to add support for the QCA9379 chipset to ath10k, specifically for the SDIO bus version.
The vendor driver treats QCA9379 chips the same as QCA9377 chips: https://git.codelinaro.org/clo/external-wlan/qcacld-2.0/-/commit/6258d7865b4d336daca097f42ca6f963e96e6f34 Device used for testing: Lenovo ThinkSmart View (CD-18781Y) containing a LITE-ON WCBN3510A (QCA9379-3) SDIO 3.0 module. The firmware and boardfile used for testing was pulled from the Android build running on the device I am using. The version string is taken from the board's /modem/verinfo/ver_info.txt and should correspond to the BSP the vendor originally used. I cannot fully verify if the firmware binaries do in fact match files of that version string from the BSP though. Maybe someone from QCA can provide the latest version of a WLAN.NPL firmware to ath10k-firmware, as my understanding is that firmwares from unofficial sources are not accepted into ath10k-firmware. If that's a possibility, official Bluetooth firmware binaries would also be appreciated. Probing the card is not entirely error free, but it does work relatively reliably nonetheless. This could have to do with the MSM8953/APQ8053 SoC possibly still having a few bugs in the mainline kernel and/or my device tree for the device not being entirely correct or complete yet.
