This leads to a compile error :

Do you compile atmel_serial as module? I compiled built-in and it was
fine
for me.
So the function should be exported like mctrl_gpio_to_gpiod() I guess.
An other reason can be you have CONFIG_GPIOLIB=n ?
In fact, mctrl_gpio_is_gpio() should depend on CONFIG_GPIOLIB for empty
body.

well, I'm also compiling it built-in (I even have config_module=N)

You have no CONFIG_GPIOLIB enabled and it is the bug in the patchset.
Thanks.
Janusz

Actually, I have CONFIG_GPIOLIB=y, only it doesn't appears in the defconfig.
I did:
# cp defconfig arch/arm/configs/toto_defconfig
# ARCH=arm make toto_defconfig

# grep CONFIG_GPIOLIB .config
CONFIG_GPIOLIB=y
CONFIG_GPIOLIB_IRQCHIP=y

# LANG=C ARCH=arm
CROSS_COMPILE=~/dev/LNS/buildroot-VIP/output/host/usr/bin/arm-linux-
make -j12 uImage
