Looks good with one modification: please make it

default ARM64 && ARCH_MEDIATEK

so the driver does not get turned on by default for ARM64 configurations that
do not contain support for mediatek chips.

Yes, this is preferred. Because we don't have MACH_MT8173, so it is
possible a ARM64 + ARCH_MEDIATEK system doesn't need PINCTRL_MT8173, so
we still need 2 slightly different logic. Is it OK if I do this?
Also add some comments so future SoCs can follow the correct template.

# For ARMv7 SoCs
config PINCTRL_MT8135
bool "Mediatek MT8135 pin control" if COMPILE_TEST && !MACH_MT8135
default MACH_MT8135
select PINCTRL_MTK_COMMON

# For ARMv8 SoCs
config PINCTRL_MT8173
bool "Mediatek MT8173 pin control"
depends on ARM64 || COMPILE_TEST
default ARM64
select PINCTRL_MTK_COMMON

The patch looks good in principle, just two small comments

You have slightly different logic here: PINCTRL_MT8135 will
always be enabled when COMPILE_TEST is on, while PINCTRL_MT8173
is enabled by default in this case, but can be turned off.

Neither of them is what you really want, which would be

config PINCTRL_MT8135
bool "Mediatek MT8135 pin control"
depends on MACH_MT8135 || COMPILE_TEST
default MACH_MT8135
select PINCTRL_MTK_COMMON

config PINCTRL_MT8135
bool "Mediatek MT8173 pin control"
depends on MACH_MT8173 || COMPILE_TEST
default MACH_MT8173
select PINCTRL_MTK_COMMON

This way, the options are only enabled by default if MACH_MT8135
or MACH_MT8173 are enabled, but you are free to enable or disable
them when COMPILE_TEST is set. Alternatively, you can do

config PINCTRL_MT8135
bool "Mediatek MT8135 pin control" if COMPILE_TEST && !MACH_MT8135
default MACH_MT8135
select PINCTRL_MTK_COMMON

config PINCTRL_MT8135
bool "Mediatek MT8173 pin control" if COMPILE_TEST && !MACH_MT8173
default MACH_MT8173
select PINCTRL_MTK_COMMON

which will let you turn on the options if COMPILE_TEST is set, but not
let you turn them off when the drivers are required.

Hi Paul,

Just sent a new version with this change.

The kconfig tools will do what you mean here, but I think it's cleaner
to make this just:
bool "Mediatek MT8173 pin control"
default y

[PATCH 2/2] pinctrl: mediatek: Adjust mt8173 pinctrl kconfig

2015-03-05 Thread Yingjoe Chen
Linus,
This one make PINCTRL_MT8173 option user selectable and is based on
mtk-staging in your tree. If you think this is OK, please applied or
squash this into previous change. Thanks.

--
ARM64 maintainer doesn't want to add MACH_* for each SoC.
Adjust mt8173 pinctrl kconfig entry so user can manually select it.

Also make PINCTRL_MT8135 build when COMPILE_TEST is enabled.
