Connecting LCD with custom Tegra K1 Board

Hi all,
We are trying to make a custom board design with Tegra K1 SoC. I connected LCD LVDS interface with DSI_A_D[3:0] P/N and DSI_A_CLK P/N of the Tegra K1. But there are other pins to be connected to the Tegra. Mainly the touch screen controller SDA/SCL lines. To which pins should they be connected? Can I connect them to GPIO?
LCD PN : AT-T070CAE-08CP
Thank you

I2C touch screen controller can be attached on GEN1_I2C or GEN2_I2C. it is not suggest connect to GPIO.
