ARM world is too fragmented. I can't take it as a good example. Most of distros would like to maintain less kernels (ideally one per architecture). In the above example it's a sub-arch. Yes, I know that x86 has 3 let's say "sub-arches" which require different settings to kernel. (None of them makes difference to pin control case though)

Instead I would propose to reorganize parent Kconfig to have something likeWell they're done in alphabetical and there's appropriate depends ARCH_ or SOC_ etc so that those architectures don't randomly pop up in configs for other unrelated things, the intel/ one is one of the only ones that doesn't do this (hence this patch)quoted
if (ARM || COMPILE_TEST) ...ARM stuff... endif if (X86 || COMPILE_TEST) ...X86 stuff... endif But personally I don't like any of the above. So, what's the issue this patch is targeting against?So that every time (in my case a distro) they don't have to explicitly have unrelated "# CONFIG_PINCTRL_CHERRYVIEW is not set" style bits through all their configs because it's completely unrelated to the platform.
Okay, so, what's wrong with defining big blocks on per ARCH basis as I pointed above? ARM, ARM64, X86, etc. -- Andy Shevchenko [off-list ref] Intel Finland Oy
