Hello, > Read the last time this came up: > > https://lore.kernel.org/linux-devicetree/71fb0ff289e84c55bd92ecd96bc9aa76@xxxxxxxxxxxxxxxxxxxxx/ Thanks a lot, this answers my question. In my case, I do not expect the kernel to apply the overlay, so I believe I avoid 99% of the complexity mentionned in that thread. Would the following patch (in reply) be acceptable ? Especially: - Is it fine to add such config option without selecting it anywhere ? - DTC_FLAGS_overlay* and DTC_FLAGS_testcases can contain -@, should I try to figure a way out to make them select this option ?
