15:24 <DC-IRC> <juanesf91> Hello everyone, I want to generate and test the ov5640 camera overlay on sun8i-r40. Should I generate an overlay for the camera and another for i2c4? Or generate one with both elements?

16:53 <DC-IRC> <viraniac> Maybe this will help https://patchwork.kernel.org/project/linux-arm-kernel/patch/20191215165924.28314-15-wens@kernel.org/

16:54 <DC-IRC> <juanesf91> I want to convert precisely that same one into an overlay. The question is to separate i2c4?

17:04 <DC-IRC> <viraniac> if you are going to put that ov5640 block in i2c4, then keep them as one, otherwise you can create two different overlays. Honestly, I think its up to you how you want to structure them as long as it works fine

18:15 <DC-IRC> <juanesf91> The csi connector of the bananapi m2 ultra is connected to csi-0 and i2c4, there is no other option. so I should do the camera overlay with i2c4 included

20:19 <DC-IRC> <Tonymac32> Yeah if the hardware is linked and there's no other use for that I2C I would say it is included

20:36 <DC-IRC> <juanesf91> https://github.com/wens/dt-overlays/blob/master/bpi-m2u-ov5640.dts

20:37 <DC-IRC> <juanesf91> I found that overlay by wens, how can I add it to the compilation to test how it works

20:42 <DC-IRC> <juanesf91> It must be added to:

20:42 <DC-IRC> <juanesf91> https://github.com/armbian/sunxi-DT-overlays

20:47 <DC-IRC> <viraniac> I don't think that repository is not under use

20:48 <DC-IRC> <juanesf91> I have to create a folder for sun8i-r40 and add inside

20:48 <DC-IRC> <viraniac> we now add things as a patch to kernel/archive/sunxi-<kernel_version>/patches.armbian

20:50 <DC-IRC> <viraniac> run ./compile.sh board=bananapim2ultra branch=current kernel-patch

20:51 <DC-IRC> <viraniac> go into cache/sources/linux-kernel-worktree/6.1__sunxi__armhf/arch/arm/boot/dts/overlay place your overlay there and also add it to Makefile thats present in that directory

20:53 <DC-IRC> <viraniac> Then go back in the terminal window where you ran kernel-patch command and it should help you create a patch that you should be able to place in the either in patch/kernel/archive/sunxi-<kernel_version> directory or userpatches/kernel/archive/sunxi-<kernel_version>/ directory

20:54 <DC-IRC> <viraniac> I don't think that repository is under use

21:52 <DC-IRC> <juanesf91> Thanks
