Research direction

Start with the provided dmesg output, especially the tsc2007 probe failure on I2C address 3-0048 and the TFT35 framebuffer line. Check the TFT35 touch connection and the board's I2C/SPI configuration against the reported hardware. Done means the touchscreen probes without error -110 and touch input works while video continues to function.
