@brief I2S controller channel configuration

Fields

id: i2s_port_t

< I2S port id

role: i2s_role_t

< I2S role, I2S_ROLE_MASTER or I2S_ROLE_SLAVE

dma_desc_num: u32

< I2S DMA buffer number, it is also the number of DMA descriptor

dma_frame_num: u32

< I2S frame number in one DMA buffer. One frame means one-time sample data in all slots, it should be the multiple of ‘3’ when the data bit width is 24.

auto_clear: bool

< Set to auto clear DMA TX buffer, i2s will always send zero automatically if no data to send
