Actually, not:

ERROR: "imx_scu_irq_register_notifier"

ERROR: "imx_scu_get_handle" [drivers/input/keyboard/imx_sc_key.ko] undefined!

If you want to enable compile test coverage you need to provide stubs
for the above functions.

Thanks.

or select IMX_SCU

or leave out COMPILE_TEST from the individual drivers as having
COMPILE_TEST for IMX_SCU is enough to be able to select the drivers.

These i.MX SCU drivers depends on IMX_SCU, I already add the COMPILE_TEST
to IMX_SCU driver as well, that is why I put these patches in a patch series. Maybe
I can add stubs as well to make sure build passed even when IMX_SCU is NOT compiled?
Will send V2 to add stubs, it makes more sense.

Thanks,
Anson

Adding "|| COMPILE_TEST" you are removing hard dependency on IMX_SCU,
which as you can see can result in broken build.

It is up to you whether you make IMX_SCU buildable with COMPILE_TEST
and leave the sub-driver as is, or add the stubs and make sub-drivers
buildable even without IMX_SCU being present.

Thanks.

Thank you, I already added COMPILE_TEST to IMX_SCU driver, and I will also add
stubs for those APIs in V2.

Thanks, I already added the COMPILE_TEST for IMX_SCU which is in this same patch series,
without that IMX_SCU COMPILE_TEST patch, the build will failed, so in V2, I also added
the stubs into those IMX SCU APIs to make sure even IMX_SCU is NOT enabled, modules
with COMPILE_TEST can still pass build, please help review V2 patch set.

Thanks,
Anson

My point is that there is no need for the stubs. Simply have
COMPILE_TEST for IMX_SCU as this is enough to extend coverage to all the
drivers and significantly reduces the code size versus what you did in
v2.

OK, then I think V1 patch set is already what you expected, patch 1/5 adds the COMPILE_TEST
for IMX_SCU. I think maintainers can just pick up the V1 patch set.
