Fix for bugs described in: https://github.com/zephyrproject-rtos/zephyr/issues/59803 1. the size argument passed to i2s_write() was being ignored. change the code so that the size is queued with the tx mem_block and the dma transfer is configured with this size. 2. change how CONFIG_I2S_MCUX_FLEXCOMM_RX_BLOCK_COUNT and CONFIG_I2S_MCUX_FLEXCOMM_TX_BLOCK_COUNT are used so that the queue buffers are allocated correctly when the two config values are not the same 3. set source_data_size and dest_data_size to be the same since the DMA controller can only set one size per DMA transfer. the driver was already computing a dest_data_size but always passing 1 for the source_data_size. For I2S RX case, I think source_data_size should be set to the expected FIFO read size instead of dest_data_size. Also some smaller improvements like: * don't allocate two dma_blocks for tx in the static dev_mem when it only needs one * memset both rx_dma_blocks together instead of separtely * set dma_cfg block_count for tx and rx statically instead of at runtime Signed-off-by: Mike J.
