Commit Message

Linus Walleij June 4, 2014, 1:33 p.m. UTC
The number of GPIOs defined for the different S5P platforms using
the tricky #define macros are actually as follows:

S5P64x0: 180 GPIOs
S5PC100: 115 GPIOs
S5PV210: 252 GPIOs

The include file <asm-generic/gpio.h> will automatically bump us
to 256 GPIOs which is a nice default value that happens to encompass
all the S5P platform requirements under its roof.

Cut ARCH_NR_GPIOS and the custom spacing macro for extra GPIOs
that is not used anywhere in the kernel.
