1130          * (1) Using "Enable Bit" of register associated with that IO
1131          * (or ADC/DAC)
1132          *      e.g. Mic Left can be enabled using bit 7 of MIC_L(0x7) reg
1133          *
1134          * (2) Using "Standby Bit" of STARTUP2 or STARTUP3 register
1135          *      e.g. Mic left can be put to STANDBY using bit 0 of STARTUP3(0x5)
1136          *
1137          * Out of these two methods, the one using STANDBY bits is preferred
1138          * way to enable/disable individual blocks. This is because STANDBY
1139          * registers are part of system controller which allows system power
1140          * up/down in a controlled, pop-free manner. Also, as per application
1141          * note of DA7210, STANDBY register bits are only effective if a
1142          * particular IO (or ADC/DAC) is already enabled using enable/disable
1143          * register bits. Keeping these things in mind, current DAPM
1144          * implementation manipulates only STANDBY bits.
1145          *
1146          * Overall implementation can be outlined as below,
1147          *
1148          * - "Enable bit" of an IO or ADC/DAC is used to enable it in probe()
1149          * - "STANDBY bit" is controlled by DAPM
