## Summary Add I2S support for RISC-V based esp devices * esp32[c3|c6|h2]: Update common layer * esp32[c3|c6|h2]: Add I2S support * esp32[c3|c6|h2]: Add DMA function to have more capabilites ## Impact ESP32-C3, ESP32-C6, ESP32-H2 ## Testing Used configs: ``` esp32c3-generic:i2schar esp32c6-devkitc:i2schar esp32h2-devkit:i2schar ``` After build step Dout (C6/C3: 18, H2: 10 default) and Din (C6/C3: 19, H2: 11 default) pins connected together via wire (or pointed to the same pin in menuconfig). After that `i2schar` command used to test it and expected output should be like this: ``` nsh> i2schar i2schar_main: Start receiver thread i2schar_read: buffer=0x40815678 buflen=57 i2s_receive: Prepared 5 bytes to receive DMA buffers Recieved Audio pipeline buffer: (0x408156ac): i2schar_read: buffer=0x408156b8 buflen=57 i2s_receive: Prepared 5 bytes to receive DMA buffers Recieved Audio pipeline buffer: (0x408156ec): i2schar_write: buffer=0x408134b8 buflen=57 i2s_tx_worker: tx.act.head=0 tx.done.head=0x4080bce0 i2schar_txcallback: apb=0x408134b8 nbytes=5 result=0 i2schar_txcallback: Freeing apb=0x408134b8 crefs=2 i2s_send: Queued 5 bytes into DMA buffers Audio pipeline buffer: (0x408134ec): 0000 00 01 02 03 04 ..... i2schar_write: buffer=0x408134f8 buflen=57 i2s_tx_worker: tx.act.head=0 tx.done.head=0x4080bce0 i2schar_txcallback: apb=0x408134f8 nbytes=5 result=0 i2schar_txcallback: Freeing apb=0x408134f8 crefs=2 i2s_send: Queued 5 bytes into DMA buffers Audio pipeline buffer: (0x4081352c): 0000 05 06 07 08 09 ..... i2schar_main: Start transmitter thread i2schar_receiver: Received buffer 1 i2schar_receiver: Received buffer 2 i2schar_main: Waiting for the transmitter thread i2schar_transmitter: Send buffer 1 i2schar_transmitter: Send buffer 2 i2schar_main: Waiting for the receiver thread ``` Note: Default pins for devices: | Device/Pin | MCLK | BCLK | WS | DIN | DOUT | |------------|------|------|----|-----|------| | ESP32-C3 | 0 | 4 | 5 | 19 | 18 | | ESP32-C6 | 0 | 4 | 5 | 19 | 18 | | ESP32-H2 | 0 | 4 | 5 | 11 | 10 | -- This is an automated message from the Apache Git Service.
