+ *
+ * (2) Using "Standby Bit" of STARTUP2 or STARTUP3 register
+ * e.g. Mic left can be put to STANDBY using bit 0 of STARTUP3(0x5)
+ *
+ * Out of these two methods, the one using STANDBY bits is preferred
+ * way to enable/disable individual blocks. This is because STANDBY
+ * 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,
