Subject: [PATCH v2 1/2] gpio: Increase ARCH_NR_GPIOs to 512

Some newer Intel SoCs, like Braswell already have more than 256 GPIOs
available so the default limit is exceeded. Instead of adding more
architecture specific gpio.h files with custom ARCH_NR_GPIOs we increase
the gpiolib default limit to be twice the current.

Signed-off-by: Mika Westerberg <>
Changes to previous version is that now we increase the common limit
instead of adding x86 specific gpio.h
