[PATCH 0/2] Backport support for Telit FN980 v1 and FN990 for 3.18

[PATCH 0/2] Backport support for Telit FN980 v1 and FN990 for 3.18

[Fabio Porcedda]

Hi,
these two patches are the backport for 3.18.y of the following commits:

commit a96ef8b504efb2ad445dfb6d54f9488c3ddf23d2
    bus: mhi: host: pci_generic: add Telit FN980 v1 hardware revisio

commit 77fc41204734042861210b9d05338c9b8360affb
    bus: mhi: host: pci_generic: add Telit FN990

The cherry-pick of the original commits don't apply because the commit
89ad19bea649 (bus: mhi: host: pci_generic: Sort mhi_pci_id_table based
on the PID, 2022-04-11) was not cherry-picked. Another solution is to
cherry-pick those three commits all togheter.

In the following days I will send backport for longterm releases.

Thanks!

There is a typo, they are for 5.18.y, but please take the newer version:
[PATCH v2 5.18 0/2] Backport support for Telit FN980 v1 and FN990

Thanks
