860 | /* |
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 | |
