Hi, Igor
We have the plan to do the upstream job of cdns3 host/gadget
drivers on
imx8.
...
Now we just have done the DM switch of cdns3 gadget driver, and
there also some changes in xhci_imx8.c.
Thanks for the details!
...
We plan to start our upstream job from next week, and the first
version will be send to maintainer within two or three weeks. We
hope it will be included in uboot v2019.07 RC2.
I'm afraid we're a bit late here.
v2019.07 is going to be released next Monday (there was a release of
v2019.07-rc4 already in June 11), so the next merge window for
v2019.10 opens July 9.
Yes, you are right.
Anyway, I will try my best and finish the upstream job as soon as possible.
...
...
Do you think this is okay?
Sounds good! Looking forward to your patches in the mailing list!
...
Best regards
Sherry sun
Just a bit off-topic, but are you aware about similar plans for
upstreaming of DPU driver for i.MX8 (driver/video/imxdpuv1.c)?
Sorry, I am not quite sure.
Ying knows more about this. Maybe he can answer you.
Best regards
Sherry sun

In NXP downstream, there is work to migrate the i.MX8
usb/gadget to
DM.
...
...
...
When that ready, the patches will be posted to community.
So do you need any help with this?
I am not working on that. But I welcome any contribution to make
more
features supported in upstream.
...
Won't you mind if we start up-streaming at
...
least xhci-imx8.c, which is used in both our SoMs Apalis iMX8
and Colibri iMX8QXP. Based on what I've seen in [1], the initial
conversion to DM_USB is already done. Is there anything else
that is expected to be changed in xhci-imx8.c (by asking this I
just want to avoid
duplicating the effort)?
...
Sherry, Jun has some work on the driver. So they might have
comments to
avoid duplicating efforts, in case they has plan recently.
...
Regards,
Peng.
...
Frankly, this is currently a kind of showstopper for us, as it
adds some complications for the next release of our BSP (we
would like to enable usb host/gadget support or iMX8-based SoMS,
including all dependent features like fastboot/usb storage/ums
etc.), where we made a decision to move towards the usage of the
mainline U-boot (with the minimal divergence and minimal amount
of legacy downstream
patches on top of it).

Peng.

Sorry for bothering you again, but do you have any updates regarding
USB-host/gadget driver up-streaming process?
Thanks
I have sent the patchset to U-Boot mailing list on July 16.
You can see it at https://patchwork.ozlabs.org/cover/1132760/ .
And any comments are welcome.
Best regards
Sherry sun
