Cross checked this few rescent changes were added configs in same file. verified added config is present in generated .config file and lt8713sx driver is compiled with it. Let me know if need to add this config is another file or at different place. > > CONFIG_DRM_LONTIUM_LT8912B=m > > CONFIG_DRM_LONTIUM_LT9611=m > > CONFIG_DRM_LONTIUM_LT9611UXC=m > > Best regards, > Krzysztof

So did you run `make savedefconfig`? If you do not understand review then at least follow what I asked for... Best regards, Krzysztof

What is the point of savedefconfig? This generate a minimal defconfig containing only non‑default options. A defconfig file is generated in my root dir, CONFIG_DRM_LONTIUM_LT8713SX is part of this generated defconfig. shall i update arch/arm64/configs/defconfig with generated defconfig and verify ? > Best regards, > Krzysztof

In which place is the config entry present in defconfig and is it the same as the one in your patch? That was the question that Krzysztof asked in the first email, which you seem to ignore. -- With best wishes Dmitry

That was the question that Krzysztof > asked in the first email, which you seem to ignore. Thank you for the clarity, I thought lexicographical order is followed here. savedefconfig generated in below order, i will follow same in v4 patch. Sorry Krzysztof i completely misunderstood the question.
