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. Change logs: v3: - Change tables in documents from literal block to table format - Change symbol namespace to string literal according to patch: cdd30ebb1b9f ("module: Convert symbol namespace to string literal") - Refine Kconfig description - Enhance Quickspi and Quicki2c driver by clearing THC hardware interal state before doing initialization to avoid BIOS impacts. - A fix in Quicki2c driver when does set_report v2: - Fix document format issues - Add THC device IDs for Intel Panther Lake (PTL) platform Even Xu (13): HID: THC: Add documentation HID: intel-thc-hid: intel-thc: Add THC DMA interfaces HID: intel-thc-hid: intel-thc: Add THC I2C config interfaces HID: intel-thc-hid: intel-quickspi: Add THC QuickSPI driver hid layer HID: intel-thc-hid: intel-quickspi: Add THC QuickSPI ACPI interfaces HID: intel-thc-hid: intel-quickspi: Add HIDSPI protocol implementation HID: intel-thc-hid: intel-quickspi: Add PM implementation HID: intel-thc-hid: intel-quicki2c: Add THC QuickI2C driver skeleton HID: intel-thc-hid: intel-quicki2c: Add THC QuickI2C driver hid layer HID: intel-thc-hid: intel-quicki2c: Add THC QuickI2C ACPI interfaces HID: intel-thc-hid: intel-quicki2c: Add HIDI2C protocol implementation HID: intel-thc-hid: intel-quicki2c: Complete THC QuickI2C driver HID: intel-thc-hid: intel-quicki2c: Add PM implementation Xinpeng Sun (9): HID: intel-thc-hid: Add basic THC driver skeleton HID: intel-thc-hid: intel-thc: Add THC registers definition HID: intel-thc-hid: intel-thc: Add THC PIO operation APIs HID: intel-thc-hid: intel-thc: Add APIs for interrupt HID: intel-thc-hid: intel-thc: Add THC LTR interfaces HID: intel-thc-hid: intel-thc: Add THC interrupt handler HID: intel-thc-hid: intel-thc: Add THC SPI config interfaces HID: intel-thc-hid: intel-quickspi: Add THC QuickSPI driver skeleton HID: intel-thc-hid: intel-quickspi: Complete THC QuickSPI driver Documentation/hid/index.rst | 1 + Documentation/hid/intel-thc-hid.rst | 568 ++++++ MAINTAINERS | 6 + drivers/hid/Kconfig | 2 + drivers/hid/Makefile | 2 + drivers/hid/intel-thc-hid/Kconfig | 42 + drivers/hid/intel-thc-hid/Makefile | 22 + .../intel-quicki2c/pci-quicki2c.c | 966 ++++++++++ .../intel-quicki2c/quicki2c-dev.h | 186 ++ .../intel-quicki2c/quicki2c-hid.c | 166 ++ .../intel-quicki2c/quicki2c-hid.h | 14 + .../intel-quicki2c/quicki2c-protocol.c | 224 +++ .../intel-quicki2c/quicki2c-protocol.h | 20 + .../intel-quickspi/pci-quickspi.c | 987 +++++++++++ .../intel-quickspi/quickspi-dev.h | 172 ++ .../intel-quickspi/quickspi-hid.c | 165 ++ .../intel-quickspi/quickspi-hid.h | 14 + .../intel-quickspi/quickspi-protocol.c | 409 +++++ .../intel-quickspi/quickspi-protocol.h | 25 + .../intel-thc-hid/intel-thc/intel-thc-dev.c | 1578 +++++++++++++++++ .../intel-thc-hid/intel-thc/intel-thc-dev.h | 116 ++ .../intel-thc-hid/intel-thc/intel-thc-dma.c | 969 ++++++++++ .../intel-thc-hid/intel-thc/intel-thc-dma.h | 146 ++ .../intel-thc-hid/intel-thc/intel-thc-hw.h | 881 +++++++++ include/linux/hid-over-i2c.h | 117 ++ include/linux/hid-over-spi.h | 155 ++ 26 files changed, 7953 insertions(+) create mode 100644 Documentation/hid/intel-thc-hid.rst create mode 100644 drivers/hid/intel-thc-hid/Kconfig create mode 100644 drivers/hid/intel-thc-hid/Makefile create mode 100644 drivers/hid/intel-thc-hid/intel-quicki2c/pci-quicki2c.c create mode 100644 drivers/hid/intel-thc-hid/intel-quicki2c/quicki2c-dev.h create mode 100644 drivers/hid/intel-thc-hid/intel-quicki2c/quicki2c-hid.c create mode 100644 drivers/hid/intel-thc-hid/intel-quicki2c/quicki2c-hid.h create mode 100644 drivers/hid/intel-thc-hid/intel-quicki2c/quicki2c-protocol.c create mode 100644 drivers/hid/intel-thc-hid/intel-quicki2c/quicki2c-protocol.h create mode 100644 drivers/hid/intel-thc-hid/intel-quickspi/pci-quickspi.c create mode 100644 drivers/hid/intel-thc-hid/intel-quickspi/quickspi-dev.h create mode 100644 drivers/hid/intel-thc-hid/intel-quickspi/quickspi-hid.c create mode 100644 drivers/hid/intel-thc-hid/intel-quickspi/quickspi-hid.h create mode 100644 drivers/hid/intel-thc-hid/intel-quickspi/quickspi-protocol.c create mode 100644 drivers/hid/intel-thc-hid/intel-quickspi/quickspi-protocol.h create mode 100644 drivers/hid/intel-thc-hid/intel-thc/intel-thc-dev.c create mode 100644 drivers/hid/intel-thc-hid/intel-thc/intel-thc-dev.h create mode 100644 drivers/hid/intel-thc-hid/intel-thc/intel-thc-dma.c create mode 100644 drivers/hid/intel-thc-hid/intel-thc/intel-thc-dma.h create mode 100644 drivers/hid/intel-thc-hid/intel-thc/intel-thc-hw.h create mode 100644 include/linux/hid-over-i2c.h create mode 100644 include/linux/hid-over-spi.h Tested-by: Mark Pearson Reviewed-by: Mark Pearson
