Yeah there should not be much need to use syscon outside scm_conf area and for I2C devices. If there's some other misc register area in dra7 in addition to scm_conf then it might make sense to use it. But in general, for the SCM registers, just a normal loadable kernel driver module doing of_ioremap on a dedicated range of registers is always a better option :) Regrds, Tony -- 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
