TWL4030_CORE was made to depend on IRQ_DOMAIN, and that is selected by USE_OF or ARM_GIC. I guess everyone here builds with USE_OF, but maybe ARCH_OMAP3 should select ARM_GIC? -- Gražvydas -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
