It will always tiled to SoC digital power domain. It's no need to control, so I think DVDD can be ignored. If not considering the I2C, and the DVDD power supply, for HW control mode, then it looks the same including sample rate. One pin to turn on the amplifier. This IC is designed for 'easy to use'. For the normal condition, HW mode will always be suggested to the customer. May I have your suggestion? If it can not be compatible, should I write two drivers, one platform driver for HW control mode, and another I2C driver for I2C SW control mode? Hope to get your feedback.
