[RFC PATCH] drivers: use 'depends on MFD_SYSCON' instead of 'select MFD_SYSCON'

Masahiro Yamada yamada.masahiro at socionext.com
Sat Feb 24 06:50:51 PST 2018 

As Documentation/kbuild/kconfig-language.txt notes, 'select' should be
used with care - it forces a lower limit of another symbol, ignoring
the dependency.

MFD_SYSCON depends on HAS_IOMEM, but several drivers with COMPILE_TEST
select it.

This causes unmet dependencies for architecture without HAS_IOMEM.

  $ make ARCH=score randconfig
  scripts/kconfig/conf  --randconfig Kconfig
  KCONFIG_SEED=0x27C47F43
  warning: (HWSPINLOCK_QCOM && AHCI_MTK && STMMAC_PLATFORM && ...)
  selects MFD_SYSCON which has unmet direct dependencies (HAS_IOMEM)

Use 'depends on' to observe the dependency.

This commit was created by the following command:

  $ find drivers -name 'Kconfig*' | xargs sed -i -e \
    's/select MFD_SYSCON$/depends on MFD_SYSCON/'

Then, COMMON_CLK_NXP and S3C2410_WATCHDOG were fixed up manually.

Also, make MFD_SYSCON 'default y' because some defconfig files may
rely on someone select's MFD_SYSCON.

If you have a better idea to fix 'unmet dependencies',
please suggest.
