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.
We've got some upstream work on-going for the display driver in kernel. Not sure about the uboot part.

Hi Igor,
Subject: Upstreaming usb host drivers for iMX8/iMX8M
Hi Peng, Ye, Peter,
Currently there in no any usb host/gadget support in the mainline U-boot, and seems that no one has posted anything yet to the mailing list (at least I haven't found anything related to this in the
ML archives).
I've spent some time testing (usb host, ums etc.) the one in the downstream NXP U-boot (I'm still not sure where is the official NXP downstream rep, because there are no any updates in [1] for the last two years, so I looked into [2], [3]), and just curious if there any plans to get it upstreamed in the near future?
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).
Regards, Peng.
Thanks and looking forward to your reply!
