Bug description:
[ Impact ]
Currently, the built-in NVM is loaded because Qualcomm hasn't released
correct NVM files until recently. This results in poor bluetooth
performance.
Firmware finally landed in upstream linux-firmware:
https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-
firmware.git/commit/?id=77a11ffc5a0aaaadc870793d02f6c6781ee9f598
Required kernel patch:
https://lore.kernel.org/all/20241116-x13s_wcn6855_fix-v2-1-c08c298d5...@quicinc.com/
[ Test Plan ]
Boot and check that the new firmware is loaded and that bluetooth connections
can be established.
dmesg:
[ 13.306736] Bluetooth: hci0: QCA Downloading qca/hpbtfw21.tlv
[ 13.962393] Bluetooth: hci0: QCA Downloading qca/hpnv21.b8c
[ Where Problems Could Occur ]
Kernel patch specific to QCA bluetooth driver. New firmware that is
only loaded on specific Qualcomm HW. Should not affect any other
users.
