[PATCH v3 2/2] net: wwan: mhi: Add network support for Foxconn T99W760

[Slark Xiao]

T99W760 is designed based on Qualcomm SDX35 chip. It use similar
architechture with SDX72/SDX75 chip. So we need to assign initial
link id for this device to make sure network available.

Can we replace this list of strinc comparisons with some kind of device
data, being set in the mhi-pci-generic driver?

If we move this MBIM-specific information into mhi-pci-generic, we
should consider using a software node (e.g. via
device_add_software_node) so that these properties can be accessed
through the generic device-property API.

Hi Loic,
The original solution is we defined this mux_id in mhi-pci-generic side and 
transfer it to MBIM side. But it is rejected in last year.
Why we move it back again?

MHI has to business in dealing with MBIM specific information as we already
concluded. So it should be handled within the WWAN subsystem.

it doesn’t make sense to include MBIM-specific fields in a generic MHI
structure. However, attaching fwnode properties could be reasonable
since the MHI PCI driver is responsible for device enumeration, and
that would keep device model specific handling fully covered in that
driver.

It’s fine to keep device-specific handling within WWAN/MBIM. However,
next time, please introduce a dedicated device data structure for the
mux-id instead of adding another strcmp.

Loic

Hi Loic,
So you answer is yes for this time. I appreciate it very much.
And I will commit another patch for fixing the name "t99w515" to 
"t99w640". I have updated it in mhi side in 2025/6.But I forgot to 
sync in MBIM side. Please refer to: 
https://lore.kernel.org/all/20250606095019.383992-1-slark_xiao@163.com/
Hope that commit won't break your decision.

To avoid such mismatch issue, I agree to use a new mechanism to
make it more convenient.
Currently, it seems only SDX75/SDX35 MBIM solution have this issue.
For whole MHI support products, only Foxconn fell into this trap.
So I hope community could help this for the new design.

Thanks

Hi Loic,
May I know when this patch would be applied into net or linux-next?
I saw the changes in MHI side has been applied.
T99W760 device would have a network problem if missing this changes in wwan
side. Please help do a checking.

Thanks

Hi Loic,
I checked above link and didn't find my changes.
This is strange since the changes in MHI side of this serial has been applied, but this 
has been ignored.
BTW, this changes may not be applicable because another change 
https://patchwork.kernel.org/project/netdevbpf/patch/20251120114115.344284-1-slark_xiao@163.com/
has been applied. 

So do you want me to resend the new changes based on the latest net baseline ?
Any serials shall be assigned? V4 shall be used?

You must re-submit this patch, targeting the net-next tree (the subj
prefix must include 'net-next'), but please note:

## Form letter - net-next-closed

The net-next tree is closed for new drivers, features, code refactoring
and optimizations due to the merge window and the winter break. We are
currently accepting bug fixes only.

Please repost when net-next reopens after Jan 2nd.

RFC patches sent for review only are obviously welcome at any time.

My bad. It's my first time to use the cover letter.
And I replace the contents and subject according to the guide but
missing those ***. Will remove it if next version is required.

Thanks
