[PATCH] soc: mediatek: turn MTK_PMIC_WRAP into visible symbols

[sean.wang]

From: Sean Wang <sean.wang@mediatek.com>

MTK_PMIC_WRAP is the basic and required configuration for those various
MediaTek PMICs, so turning MTK_PMIC_WRAP into visible symbols easily
allows users tending to have the enablement for those PMICs.

I can't really make sense of the sentence above, sorry, and can't see
how it matches the change below anyway. MTK_PMIC_WRAP is already a
visible symbol before this change. The change is probably good in
itself, but please try to come up with a better description.

Your other patch now removes the ARCH_MEDIATEK dependency
and allows enabling the driver for COMPILE_TEST on architectures
that might not have ARCH_HAS_RESET_CONTROLLER set,
so you cannot 'select' the symbol in general.

I think a better solution is to leave the 'depends on
RESET_CONTROLLER' present here, but instead add
'select RESET_CONTROLLER' to the ARCH_MEDIATEK
definition.

Generally speaking, we don't want to mix 'select' and 'depends on'
statements for the same symbol, but if we do, it should be done
consistently in a very clear hierarchy. In case of RESET_CONTROLLER,
the rule seems to be to 'select' it from architectures and platforms,
while using 'depends on' from device drivers that absolutely require it.

Note that for compile-testing, it should be fine to rely on the fallback
definitions in include/linux/reset.h, so you might be able to just
remove the 'depends on' statement completely.

In any case, please try to be clearer about what the patch
actually tries to achieve. Did you run into a build error without
it? If so, please copy the exact build error message into the
patch description.

Thanks for your both suggestions and idea

No any compile error is present prior to the patch.

In the initial thought, I simply would like to allow the configuration
item able to be visible in menuconfig without visiting all dependencies
for it, especially for those SoC-required drivers when the corresponding
architecture target is already picked up.

I prefer to the better solution leaving 'depends on RESET_CONTROLLER'
present here, and add additional 'select ARCH_RESET_CONTROLLER' to the
ARCH_MEDIATEK definition, which could reach the goal initially I'd try
to. So I will update them in this way in the next version, including a
better description of the patch.

architecture target is already picked up.

I prefer to the better solution leaving 'depends on RESET_CONTROLLER'
present here, and add additional 'select ARCH_RESET_CONTROLLER' to the
ARCH_MEDIATEK definition, which could reach the goal initially I'd try
to. So I will update them in this way in the next version, including a
better description of the patch.
