02:22 <tokyovigilante> Just to confirm, should I expect to be able to get USB gadget ethernet working on my board?

02:22 <tokyovigilante> Been unsuccessful so far but not sure if its a HW limitation, just unimplemented, or PEBKAC

04:21 <Jookia> fi you can get fel working you probably should be able to. not sure

05:48 <Jookia> looks like using builtin fdt in a regular boot flow isn't possible with FIT images, and i can't just use the same device tree source code across linux and u-boot because the includes are different

05:59 <Jookia> oh, OF_UPSTREAM fixes that

06:41 <Jookia> the pwm driver in linux expects all data about a channel and its state to be passed as a struct... i guess we're doing it the OLD FASHIONED WAY

10:25 <apritzel> Jookia: sunxi doesn't support OF_UPSTREAM yet, and doing so would break compatibility with kernels before v5.13

10:26 <Jookia> i mean ... WorksForMe

10:26 <Jookia> but i'm on 6.10

10:26 <apritzel> there are more than one user, I hear ;-)

10:26 <apritzel> but what is the exact problem with copying in the Linux DTs into the U-Boot tree?

10:26 <Jookia> oh, there's no problem after using OF_UPSTREAM

10:27 <apritzel> yes, you have to adjust some paths, but that's what I do every few weeks or so

10:27 <apritzel> and it only affects some SoCs

10:27 <Jookia> in my case it works and i can use linux dts on u-boot

10:28 <Jookia> so i'll work on that cleanup in my buildroot eventually

10:28 <apritzel> the idea is to have your DT reviewed in Linux, then this gets copied to the U-Boot tree, which is the only DTB you will ever need to use

10:28 <Jookia> yeah, i like that idea

10:30 <apritzel> this is what we do atm, with the only caveat being that the sync is manual: https://lore.kernel.org/u-boot/20240424001808.14388-2-andre.przywara@arm.com/

10:31 <apritzel> the D1/T113-s3 is not affected by the R-INTC compatibility problem, though it suffers from the include path problem

10:32 <Jookia> yeah

10:32 <apritzel> tokyovigilante: USB peripheral support should work in general, and I definitely used that - even with multiple gadgets at once - before

10:33 <apritzel> tokyovigilante: I just cannot say how much testing I did on the H616, specifically

10:37 <apritzel> tokyovigilante: setting it up the modern Linux way (using gadgetfs) isn't trivial (and "modprobe g_ether" is legacy by now), but once you wrap your head around it, it's very powerful and can be nicely scripted

10:38 <apritzel> I think https://www.collabora.com/news-and-blog/blog/2019/02/18/modern-usb-gadget-on-linux-and-how-to-integrate-it-with-systemd-part-1/ is the page I used

10:38 <apritzel> (you can ignore the systemd part)

10:39 <Jookia> yeah i do that

14:43 <Schimsalabim> jernej: thanks for the review.

15:00 <Schimsalabim> apritzel: shall i send my remarks with regard to the patch sending descrition on the wiki to you or is someone else better suited ? thanks.

15:20 <apritzel> Schimsalabim: can you fix that up in the Wiki yourself? If not, put it in the discussion page, I guess

15:31 <Schimsalabim> ok thanks lemme see what i can do
