I'd rather extend it to other architectures than limit it to builds that have vexpress enabled. > diff --git a/drivers/clk/versatile/Kconfig b/drivers/clk/versatile/Kconfig > index ac766855ba16..826750292c1e 100644 > --- a/drivers/clk/versatile/Kconfig > +++ b/drivers/clk/versatile/Kconfig > @@ -5,8 +5,8 @@ config ICST > config COMMON_CLK_VERSATILE > bool "Clock driver for ARM Reference designs" > depends on ARCH_INTEGRATOR || ARCH_REALVIEW || \ > - ARCH_VERSATILE || ARCH_VEXPRESS || ARM64 || \ > - COMPILE_TEST > + ARCH_VERSATILE || ARCH_VEXPRESS || COMPILE_TEST > + depends on ARM64 It's definitely wrong to limit this to 64 bit.

Yes, the cover letter for this series needs to be a lot better. Sorry. In summary, I found a bunch of drivers in defconfig that were getting called in early_initcall and core_initcall even when the platform or COMPILE_TEST was not enabled. So I was just trying to ring fence some of those drivers as a proof of concept to see if these changes were acceptable upstream. Let me try again with a better cover letter and using the pattern Arnd suggested elsewhere. > > Signed-off-by: Amit Kucheria <amit.kucheria@linaro.org> > > --- > > drivers/bus/Kconfig | 2 +- > > drivers/clk/versatile/Kconfig | 4 ++-- > > 2 files changed, 3 insertions(+), 3 deletions(-) > > > > diff --git a/drivers/bus/Kconfig b/drivers/bus/Kconfig > > index d80e8d70bf10..b2b1beee9953 100644 > > --- a/drivers/bus/Kconfig > > +++ b/drivers/bus/Kconfig > > @@ -166,7 +166,7 @@ config UNIPHIER_SYSTEM_BUS > > > > config VEXPRESS_CONFIG > > bool "Versatile Express configuration bus" > > - default y if ARCH_VEXPRESS > > + depends on ARCH_VEXPRESS > > depends on ARM || ARM64 > > depends on OF > > select REGMAP > > diff --git a/drivers/clk/versatile/Kconfig b/drivers/clk/versatile/Kconfig > > index ac766855ba16..826750292c1e 100644 > > --- a/drivers/clk/versatile/Kconfig > > +++ b/drivers/clk/versatile/Kconfig > > @@ -5,8 +5,8 @@ config ICST > > config COMMON_CLK_VERSATILE > > bool "Clock driver for ARM Reference designs" > > depends on ARCH_INTEGRATOR || ARCH_REALVIEW || \ > > - ARCH_VERSATILE || ARCH_VEXPRESS || ARM64 || \ > > - COMPILE_TEST > > + ARCH_VERSATILE || ARCH_VEXPRESS || COMPILE_TEST > > + depends on ARM64 > > This will break 32-bit platforms. > > -- > Regards, > Sudeep
