The 88w8897 was a legacy Marvell chipset, while the newer chipsets we are trying to add here are branded under "NXP".
Most of the newer chipset download FW using V3 protocol and few of them use V1 protocol, which is still different from the V1 protocol seen for 8897 chip.

Initially we tried to add support for NXP chipsets in hci line-discipline, but Marcel Holtmann advised us to implement this standalone driver based on serdev.

Thanks,
