Need some help to connect Touchscreen via GPIO

Hello,
I have a LattePanda with Windows 10 and a Display from waveshare: 10.1" HDMI LCD with Touchscreen.

Now I should connect the Touchscreen via GPIO. Which PINS must I use?
  • LattePanda - waveshare Display:
    MISO - TP_SO
    MOSI - TP_SI
    SCK - TP_SCK
    ??? - TP_IRQ
    ??? - TP_CS
You see, I have MISO, MOSI and SCK. There are 2 additional Pins on the waveshare TP_IRQ and TP_CS. To which Pins on the LattePanda I must connect these 2 Pins?

There are these Pins on the waveshare-Display:

PIN NO. | SYMBOL | DESCRIPTION
1, 17 | 3.3V | Power positive (3.3V power input)
2, 4 | 5V | Power positive (5V power input)
3, 5, 7, 8, 10, 11, 12, 13, 15, 16, 18, 24 | NC | NC
6, 9, 14, 20, 25 | GND | Ground
19 | TP_SI | SPI data input of Touch Panel
21 | TP_SO | SPI data output of Touch Panel
22 | TP_IRQ | Touch Panel interrupt, low level while the Touch Panel detects touching
23 | TP_SCK | SPI clock of Touch Panel
26 | TP_CS | Touch Panel chip selection, low active
