* **New Features** * Added I2S audio support (i2s0) for LilyGO TLora Pager, M5Stack Cardputer (standard & Adv), M5Stack Core2, M5Stack CoreS3, and Guition JC1060P; moved i2s0 entry in LilyGO TDeck. * **Chores** * Device-tree grammar now separately recognizes and ignores line (//) and block (/* */) comments. * Added reference docs to severa DTS files * **Documentation** * Reworked ideas/roadmap
