The firmware-name property has been expanded to specify the names of NVM and rampatch firmware for certain chips, such as the QCA6698 Bluetooth chip. Although it shares the same IP core as the WCN6855, the QCA6698 has different RF components and RAM sizes, necessitating new firmware files. This change allows for the configuration of NVM and rampatch in DT. Possible configurations: firmware-name = QCA6698/hpnv21.bin, QCA6698/hpbtfw21.tlv; firmware-name = QCA6698/hpnv21, QCA6698/hpbtfw21.tlv; Signed-off-by: Cheng Jiang <quic_chejiang@quicinc.com> --- drivers/bluetooth/btqca.c | 82 +++++++++++++++++++------------------ drivers/bluetooth/btqca.h | 5 ++- drivers/bluetooth/hci_qca.c | 22 +++++++--- 3 files changed, 63 insertions(+), 46 deletions(-)
