* For DA7210 codec, there are two ways to enable/disable analog IOs
* and ADC/DAC,
* (1) Using "Enable Bit" of register associated with that IO
* (or ADC/DAC)
* e.g. Mic Left can be enabled using bit 7 of MIC_L(0x7) reg
*
* (2) Using "Standby Bit" of STARTUP2 or STARTUP3 register
* e.g. Mic left can be put to STANDBY using bit 0 of STARTUP3(0x5)
*
* Out of these two methods, the one using STANDBY bits is preferred
* way to enable/disable individual blocks. This is because STANDBY
* registers are part of system controller which allows system power
* up/down in a controlled, pop-free manner. Also, as per application
* note of DA7210, STANDBY register bits are only effective if a
* 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.
*
* Overall implementation can be outlined as below,
*
* - "Enable bit" of an IO or ADC/DAC is used to enable it in probe()
* - "STANDBY bit" is controlled by DAPM
