[U-Boot] Upstreaming usb host drivers for iMX8/iMX8M

[U-Boot] Upstreaming usb host drivers for iMX8/iMX8M

[Igor Opaniuk]

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?

Thanks and looking forward to your reply!

I will let the NXP folks comment about the i.MX8 USB upstreaming
plans, but just wanted to point you to the latest NXP U-Boot tree:

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? 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)?

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).

I am not working on that. But I welcome any contribution to make more features
supported in upstream.

Sherry, Jun has some work on the driver. So they might have comments
to avoid duplicating efforts, in case they has plan recently.

[U-Boot] Upstreaming usb host drivers for iMX8/iMX8M

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.

Sounds good! Looking forward to your patches in the mailing list!

Just a bit off-topic, but are you aware about similar plans for
upstreaming of DPU driver for i.MX8 (driver/video/imxdpuv1.c)?
