1111          * For DA7210 codec, there are two ways to enable/disable analog IOs
1112          * and ADC/DAC,
1113          * (1) Using "Enable Bit" of register associated with that IO
1114          * (or ADC/DAC)
1115          *      e.g. Mic Left can be enabled using bit 7 of MIC_L(0x7) reg
1116          *
1117          * (2) Using "Standby Bit" of STARTUP2 or STARTUP3 register
1118          *      e.g. Mic left can be put to STANDBY using bit 0 of STARTUP3(0x5)
1119          *
1120          * Out of these two methods, the one using STANDBY bits is preferred
1121          * way to enable/disable individual blocks. This is because STANDBY
1122          * registers are part of system controller which allows system power
1123          * up/down in a controlled, pop-free manner. Also, as per application
1124          * note of DA7210, STANDBY register bits are only effective if a
1125          * particular IO (or ADC/DAC) is already enabled using enable/disable
1126          * register bits. Keeping these things in mind, current DAPM
1127          * implementation manipulates only STANDBY bits.
1128          *
1129          * Overall implementation can be outlined as below,
1130          *
1131          * - "Enable bit" of an IO or ADC/DAC is used to enable it in probe()
1132          * - "STANDBY bit" is controlled by DAPM
