SDIO function 1 loads the Bluetooth firmware; HCI traffic uses a separate UART interface with H4 framing at 1500000 baud and hardware flow control. The series adds the AIC vendor prefix, Device Tree bindings for the two interfaces, and the btaic driver with build and maintainer integration. The UART node references its SDIO firmware provider through the aic,firmware-sdio property. Validation status: - The vendor has confirmed that SDIO firmware loading works. - UART HCI communication, controller initialization, scanning, pairing, connections and data transfer have not yet been validated. - Suspend/resume and Wi-Fi/Bluetooth coexistence have not been validated. - No hardware functionality beyond firmware loading is claimed. This is an RFC for implementation and binding review, not a request for merging at this stage. Feedback is particularly welcome on the SDIO/UART split, the firmware-provider association and the device lifetime handling. The driver requests the following external firmware files: aic/aic8800d80/fw_adid_8800d80_u02.bin aic/aic8800d80/fw_patch_8800d80_u02.bin aic/aic8800d80/fw_patch_table_8800d80_u02.bin Firmware binaries are not included in this kernel patch series.
