+	 *
+	 * Out of these two methods, the one using STANDBY bits is preferred

+	 * registers are part of system controller which allows system power
+	 * up/down in a controlled, pop-free manner. Also, as per application
+	 * note of DA7210, STANDBY register bits are only effective if a
+	 * particular IO (or ADC/DAC) is already enabled using enable/disable
+	 * register bits. Keeping these things in mind, current DAPM
+	 * implementation manipulates only STANDBY bits.
+	 *
+	 * Overall implementation can be outlined as below,
