Hi,
I am using the QCA9377 chip on an imx6dl-pico-pi board running kernel
5.10.37 and I noticed that the firmware takes a long time to load
(more than 3 minutes after boot):

Does anyone have any suggestions for fixing these two issues? I have
also tested 5.12.4 with the same results. Using the QCA9377 firmware
from the latest linux-firmware tree.
