1125 	 * registers are part of system controller which allows system power
1126 	 * up/down in a controlled, pop-free manner. Also, as per application
1127 	 * note of DA7210, STANDBY register bits are only effective if a
1128 	 * particular IO (or ADC/DAC) is already enabled using enable/disable
1129 	 * register bits. Keeping these things in mind, current DAPM
1130 	 * implementation manipulates only STANDBY bits.
1131 	 *
1132 	 * Overall implementation can be outlined as below,
1133 	 *
1134 	 * - "Enable bit" of an IO or ADC/DAC is used to enable it in probe()
1135 	 * - "STANDBY bit" is controlled by DAPM
