We don't want to have the GPIO registers available in the common headers as otherwise we'll get tons of drivers that suddenly start tinkering with these registers directly.. > +/* > + * omap24xx GPIO base addresses > + */ > +#define OMAP242X_GPIO1_BASE 0x48018000 > +#define OMAP242X_GPIO2_BASE 0x4801a000 > +#define OMAP242X_GPIO3_BASE 0x4801c000 > +#define OMAP242X_GPIO4_BASE 0x4801e000 > + > +#define OMAP243X_GPIO1_BASE 0x4900C000 > +#define OMAP243X_GPIO2_BASE 0x4900E000 > +#define OMAP243X_GPIO3_BASE 0x49010000 > +#define OMAP243X_GPIO4_BASE 0x49012000 > +#define OMAP243X_GPIO5_BASE 0x480B6000 These should go into mach-omap2/gpioxxxx.c.
