p.s.

Looking at the latest simatic pdx86 code:

https://git.kernel.org/pub/scm/linux/kernel/git/pdx86/platform-drivers-x86.git/log/?h=platform-drivers-x86-simatic-ipc

I see 5 Kconfig options and 5 .c files directly under

drivers/platform/x86/

at this point I think it would be nice to move this into its
own simatic subdir: drivers/platform/x86/simatic

with its own Makefile and Kconfig to avoid cluttering the main
drivers/platform/x86 dir and Kconfig too much.

Can you prepare a patch for this on top of:

https://git.kernel.org/pub/scm/linux/kernel/git/pdx86/platform-drivers-x86.git/log/?h=platform-drivers-x86-simatic-ipc

?

See:

https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=f1e1ea516721d1ea0b21327ff9e6cb2c2bb86e28

For an example of a similar move done for Dell.

Note this example also adds

"default m"

to all options except for the main X86_PLATFORM_DRIVERS_DELL (X86_PLATFORM_DRIVERS_SIMATIC in this case) so that on interactive make config only the X86_PLATFORM_DRIVERS_SIMATIC will gets asked about and then the rest will automatically get enabled as modules.

Hans
