* **New Features** * ESP32 I2S controller support: runtime-configurable digital audio I/O with read/write/set/get operations and multiple formats. * **Board Support** * LilyGO T-Deck device tree entry added to enable I2S peripheral pin configuration. * **Documentation** * New/updated bindings and descriptors for I2S, I2C, GPIO, and root nodes. * **Other** * Added GPIO "no pin" sentinel and exposed I2S controller API symbols.
