| THC (Touch Host Controller) is the name of the IP block in PCH that | |
| interfaces with Touch Devices (ex: touchscreen, touchpad etc.). It | |
| is comprised of 3 key functional blocks: A natively half-duplex | |
| Quad I/O capable SPI master; a low latency I2C interface to support | |
| HIDI2C compliant devices; a hardware sequencer with Read/Write DMA | |
| capability to system memory. | |
| Say Y/M here if you want to support Intel THC. If unsure, say N. | |

| Intel QuickSPI, based on Touch Host Controller (THC), implements | |
| HIDSPI (HID over SPI) protocol. It configures THC to work at SPI | |
| mode, and controls THC hardware sequencer to accelerate HIDSPI | |
| transaction flow. | |
