## Device Tree Files

### Kernel Device Tree

```bash
kernel/linux-5.4/arch/arm/boot/dts/t113-s3-kickpi-k4b.dts  
# This file selects the active screen device tree. Only one can be chosen.  
# Default: 7-inch LVDS screen. Ensure consistency with U-Boot configuration.  

//#include "t113-s3-kickpi-lcd-tv.dtsi"  
#include "t113-s3-kickpi-lcd-lvds-7-1024-600.dtsi"  
//#include "t113-s3-kickpi-lcd-mipi-10-800-1280.dtsi"  
//#include "t113-s3-kickpi-lcd-mipi-8-800-1280.dtsi"  
```

### U-Boot Device Tree

```bash
t113-linux/brandy/brandy-2.0/u-boot-2018/arch/arm/dts/t113-s3-kickpi-k4b-uboot.dts  
# This file selects the active screen device tree. Only one can be chosen.
