861 * For DA7210 codec, there are two ways to enable/disable analog IOs
862 * and ADC/DAC,
863 * (1) Using "Enable Bit" of register associated with that IO
864 * (or ADC/DAC)
865 * e.g. Mic Left can be enabled using bit 7 of MIC_L(0x7) reg
866 *
867 * (2) Using "Standby Bit" of STARTUP2 or STARTUP3 register
868 * e.g. Mic left can be put to STANDBY using bit 0 of STARTUP3(0x5)
869 *
870 * Out of these two methods, the one using STANDBY bits is preferred
871 * way to enable/disable individual blocks. This is because STANDBY
872 * registers are part of system controller which allows system power
873 * up/down in a controlled, pop-free manner. Also, as per application
874 * note of DA7210, STANDBY register bits are only effective if a
875 * particular IO (or ADC/DAC) is already enabled using enable/disable
876 * register bits. Keeping these things in mind, current DAPM
877 * implementation manipulates only STANDBY bits.
878 *
879 * Overall implementation can be outlined as below,
880 *
881 * - "Enable bit" of an IO or ADC/DAC is used to enable it in probe()
882 * - "STANDBY bit" is controlled by DAPM
