It's defined for both devices that include this dtsi.. perhaps you could remove it from there KonradI don't have a judyp to test with and prefer to limit scope.This is a mechanical change KonradSorry, I tried to have a look at what you meant but didn't quite understand. In this patch I changed the dtsi that is included by both already. I don't see any other reserved-mem nodes in judyp. Do you mean I should remove the framebuffer from judyp? I don't think that's wise since a panel driver isn't added as far as I know.I think this warning likely comes from sdm845-mainline repo, as it has extra patches, which trying to abstract framebuffer into sdm845.dtsi, where it likely conflicts, have you tried against clean 6.18-rcX or next?... or sdm845-next repo [1]? I sent the patches moving framebuffer from sdm845-mainline repository as RFC [2], but so far it's not clear to me if these should go in or not.
Ok I only did a marginal amount of grepping and judyln/judyp define framebuffer@9d400000 as the framebuffer device, while sdm845-lg-common defines memory@9d400000 as a memory region. I assumed they were all the latter. I don't see any other framebuffer@9d400000 in sdm845.dtsi so perhaps David is right.. Konrad
