Series [1/4] gpio: remove broken irq_to_gpio() interface | expand

Commit Message

Arnd Bergmann Feb. 15, 2016, 3:46 p.m. UTC 
The ARM version of asm/gpio.h basically just contains the same definitions
as the gpiolib version, with the exception of ARCH_NR_GPIOS.

This adds the option for overriding the constant through Kconfig to
the architecture-independent header, and removes the ARM version at
the same time.

This patch depends on a series done by Bjorn Helgaas, and the patch
removing irq_to_gpio().
