Hi, these two patches are backports for 6.12.y of the following commits:
commit d2b91b3097c693f784393a28801a3885778615df bus: mhi: host: pci_generic: Add Telit FN920C04 modem support
commit 00559ba3ae740e7544b48fb509b2b97f56615892 bus: mhi: host: pci_generic: Add Telit FN990B40 modem support
The cherry-pick of the original commits don't apply so I made this patches after fixing the conflict.
Regards
Daniele Palmas (2): bus: mhi: host: pci_generic: Add Telit FN920C04 modem support bus: mhi: host: pci_generic: Add Telit FN990B40 modem support
