| * For DA7210 codec, there are two ways to enable/disable analog IOs |

| * (1) Using "Enable Bit" of register associated with that IO |

| * 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() |
