As far as I understand vddmem is not used on mx28evk. From the mx28 reference manual; "11.12.8 VDDMEM Supply Targets Control Register (HW_POWER_VDDMEMCTRL) This register controls the voltage target for a memory supply generated from VDDA. This supply is intended for use with external memories such as LV-DDR that have unique voltage requirements not compatible with VDDIO, VDDA , or VDDD." -- To unsubscribe from this list: send the line "unsubscribe cpufreq" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
