Thanks Linus,

I sent a separate patch to fix this up the way I want it with the file named gpio-aspeed-sgpio.c and 
CONFIG_GPIO_ASPEED_SGPIO.

I don't want to mix up the namespaces of something Aspeed-generic with the namespace of the GPIO 
subsystem. SGPIO is the name of a specific Aspeed component.

Yours,
Linus Walleij

I agree and gpio-aspeed-sgpio.c is better.
