1119         * (or ADC/DAC)
1120         *      e.g. Mic Left can be enabled using bit 7 of MIC_L(0x7) reg
1121         *
1122         * (2) Using "Standby Bit" of STARTUP2 or STARTUP3 register

1125         * Out of these two methods, the one using STANDBY bits is preferred
1126         * way to enable/disable individual blocks. This is because STANDBY
1127         * registers are part of system controller which allows system power
1128         * up/down in a controlled, pop-free manner. Also, as per application
1129         * note of DA7210, STANDBY register bits are only effective if a
1130         * particular IO (or ADC/DAC) is already enabled using enable/disable
1131         * register bits. Keeping these things in mind, current DAPM
1132         * implementation manipulates only STANDBY bits.
1133         *
1134         * Overall implementation can be outlined as below,
1135         *
1136         * - "Enable bit" of an IO or ADC/DAC is used to enable it in probe()
1137         * - "STANDBY bit" is controlled by DAPM
