+ * For DA7210 codec, there are two ways to enable/disable analog IOs

+ *
+ * (2) Using "Standby Bit" of STARTUP2 or STARTUP3 register
+ * e.g. Mic left can be put to STANDBY using bit 0 of STARTUP3(0x5)

+ * registers are part of system controller which allows system power

+ * 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.
