could I please get some feedback on this? Mainly I'm wondering whether there is some way I could get this in (the basic support, without the hack in the third patch) without the firmware as I have unfortunately not been successful in my communication with NXP yet. To reiterate, the firmware is generally available but is not part of linux-firmware and the entire process of upstreaming the chipset support is stuck on that. Thank you, best regards, K. B.
