Subject: [PATCH v1 00/22] Add Intel Touch Host Controller drivers
Intel Touch Host Controller (THC) is a new high performance input IP
which can benefit HID device's data transaction, such as touch screen,
touch pad, stylus.
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.
