| 1128 | * For DA7210 codec, there are two ways to enable/disable analog IOs |
| 1129 | * and ADC/DAC, |
| 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 |
