2025-06-10HID: Intel-thc-hid: Intel-quicki2c: Enhance QuickI2C reset flowEven Xu
During customer board enabling, it was found: some touch devices prepared reset response, but either forgot sending interrupt or THC missed reset interrupt because of timing issue. THC QuickI2C driver depends on interrupt to read reset response, in this case, it will cause driver waiting timeout. This patch enhances the flow by adding manually reset response reading after waiting for reset interrupt timeout.

2025-02-03HID: intel-thc: fix CONFIG_HID dependencyArnd Bergmann
In drivers/hid/, most drivers depend on CONFIG_HID, while a couple of the drivers in subdirectories instead depend on CONFIG_HID_SUPPORT and use 'select HID'. With the newly added INTEL_THC_HID, this causes a build warning for a circular dependency: WARNING: unmet direct dependencies detected for HID Depends on [m]: HID_SUPPORT [=y] && INPUT [=m] Selected by [y]: - INTEL_THC_HID [=y] && HID_SUPPORT [=y] && X86_64 [=y] && PCI [=y] && ACPI [=y] WARNING: unmet direct dependencies detected for INPUT_FF_MEMLESS Depends on [m]: INPUT [=m] Selected by [y]: - HID_MICROSOFT [=y] && HID_SUPPORT [=y] && HID [=y] - GREENASIA_FF [=y] && HID_SUPPORT [=y] && HID [=y] && HID_GREENASIA [=y] - HID_WIIMOTE [=y] && HID_SUPPORT [=y] && HID [=y] && LEDS_CLASS [=y] - ZEROPLUS_FF [=y] && HID_SUPPORT [=y] && HID [=y] && HID_ZEROPLUS [=y] Selected by [m]: - HID_ACRUX_FF [=y] && HID_SUPPORT [=y] && HID [=y] && HID_ACRUX [=m] - HID_EMS_FF [=m] && HID_SUPPORT [=y] && HID [=y] - HID_GOOGLE_STADIA_FF [=m] && HID_SUPPORT [=y] && HID [=y] - PANTHERLORD_FF [=y] && HID_SUPPORT [=y] && HID [=y] && HID_PANTHERLORD [=m] It's better to be consistent and always use 'depends on HID' for HID drivers. The notable exception here is USB_KBD/USB_MOUSE, which are alternative implementations that do not depend on the HID subsystem. Do this by extending the "if HID" section below, which means that a few of the duplicate "depends on HID" and "depends on INPUT" statements can be removed in the process.

2025-01-09HID: intel-thc-hid: intel-thc: Add THC DMA interfacesEven Xu
As THC PIO only has 64 bytes FIFO length, THC DMAs are introduced to send/receive large data packets. THC has three types of DMA channels: Read DMA channel (RxDMA), Write DMA channel (TxDMA) and Software DMA (SWDMA). In addition to basic DMA functions, THC RxDMA also includes an auto hardware sequence which can handle external touch device's interrupt automatically without software involved. THC RxDMA channel usually is used for handling touch input reports. THC TxDMA is very similar with general IO TxDMA, and usually is used for sending command/request to exteranl touch device. THC SWDMA can perform read, write followed by read operation according to different configurations. Unlike RxDMA triggered by bus activity, SWDMA can be triggered by SW driver at any time, for example: - Retrieving an input report without interrupt - Sending command followed by reading response THC DMA operation flow includes 4 steps: 1. Allocate DMA buffers 2. Configure opcode, fill PRD table with DMA buffers, enable DMA channel 3. Wait for completion, read out DMA buffers and update buffer pointers 4. Stop DMA and release DMA buffers THC Hardware layer driver provides APIs for all above DMA Steps.
