THC IP now evoluates to V4, it can support 3 different modes: IPTS, HIDSPI and HIDI2C. Here are upgrade history: - THC v1, for TGL/LKF, supports intel private IPTS (Intel Precise Touch and Stylus) protocol ( IPTS mode) - THC v2, for ADL, add industrial standard HID over SPI protocol support (HIDSPI mode) - THC v3, for MTL, enhance HID over SPI mode - THC v4, for LNL, add inudstrial standard HID over I2C protocol support (HIDI2C mode) Linux Surface community (https://github.com/linux-surface) already implemented IPTS mode. These patch series provides THC HIDSPI mode and THC HIDI2C mode support on Linux. These patch series includes: 1. Document for THC hardware and software introduction. 2. Intel THC Hardware layer driver which provides control interfaces for protocol layer. 3. Intel QuickSPI (R) driver working as a HIDSPI device driver which implements HID over SPI protocol and flow. 4. Intel QuickI2C (R) driver working as a HIDI2C device driver which implements HID over I2C protocol and flow.
