I'm not aware of anything that might be missing. That said, I am not aware of every single config in every subsystem. IMO the various driver owners should be responsible for adding their configs to defconfig. > > And I don't really see the need to split these into individual patches, > maybe, take a hint from [1] > > > [1] https://lore.kernel.org/linux-arm-kernel/20200630171500.11438-1-geert+renesas@glider.be/ > Sounds good.

Is that needed for boot support? If it is only needed with UHS cards, that does not seem important enough for me.

That is debatable, as it just increases the kernel size / build time for everybody. Personally I would merge only things that are absolutely necessary, for everything else we can just do local config modifications. -Tero -- Texas Instruments Finland Oy, Porkkalankatu 22, 00180 Helsinki.

If it is only needed with UHS cards, that does not seem important enough for me. We can already boot the board via other means. Without these configs, the regulator drivers keep EPROBE_DEFERing waiting for their gpio drivers to probe and SD card never comes up. This configuration happens before any UHS capabilities are detected.

"Enable support for devices compatible with TI's davinci gpio controllers." Does'nt quite explain the severity of the patches. -- Regards, Nishanth Menon Key (0xDDB5849D1736249D) / Fingerprint: F8A2 8693 54EB 8232 17A3 1A34 DDB5 849D 1736 249D ^ permalink raw reply [flat|nested] 13+ messages in thread
