I think we need .dbck_flag = false, here -- we don't have a dbclk on omap7xx. Without this, we get: omap_gpio omap_gpio.5: Could not get gpio dbck omap_gpio omap_gpio.6: Could not get gpio dbck This needs to be added to the other 5 GPIO blocks in this file as well. - Cory -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
