You need to list the items and describe them. See how all other bindings do it. Best regards, Krzysztof

Expand the firmware-name property to specify the names of NVM and rampatch firmware to load. This update will support loading specific firmware (nvm and rampatch) for certain chips, like the QCA6698 Bluetooth chip, which shares the same IP core as the WCN6855 but has different RF components and RAM sizes, requiring new firmware files. We might use different connectivity boards on the same platform. For example, QCA6698-based boards can support either a two-antenna or three-antenna solution, both of which work on the sa8775p-ride platform. Due to differences in connectivity boards and variations in RF performance from different foundries, different NVM configurations are used based on the board ID. So In firmware-name, if the NVM file has an extension, the NVM file will be used. Otherwise, the system will first try the .bNN (board ID) file, and if that fails, it will fall back to the .bin file. Possible configurations: firmware-name = "QCA6698/hpnv21.bin", "QCA6698/hpbtfw21.tlv"; firmware-name = "QCA6698/hpnv21", "QCA6698/hpbtfw21.tlv"; firmware-name = "QCA6698/hpnv21.bin"; Signed-off-by: Cheng Jiang <quic_chejiang@quicinc.com> --- .../bindings/net/bluetooth/qualcomm-bluetooth.yaml | 5 ++++- 1 file changed, 4 insertions(+), 1 deletion(-)
