The context is that there are many folks out there (me included - Lenovo P52) with devices that have the xmm-7360 built-in, can't switch it to USB mode (prevented by OEM), and currently require [1]. That kind of works but is not really the final solution. So I also kicked off [2] there.

I know. I'm not an expert on the details, but reading the overall architectures of the IOSM and what has been reverse-engineered for the 7360, there seem to be some similarities. So, maybe you can explain to the community if that is a reasonable path to upstream 7360 support, or if at least the pattern of the 7560 could/should be transferred to the 7360 driver.
Thanks, Jan
