nuttx/boards/xtensa/esp32/esp32-devkitc/src/esp32_bringup.c
Tiago Medicci Serrano 3b5ab27893 esp32/i2s: implement I2S receiver module 
- Add ioctl method to enable allocating the apb buffer.
- Add RX methods to set data width, sample rate, channels and
for receiving data from the I2S peripheral.
- Update the i2schar defconfig to enable the I2S receiver.
- Add nxlooper defconfig to enable testing the RX interface.
- Add specific bindings on ESP32 bringup to enable nxlooper
to work without the need of any specific codec.
