Wildfire Luban Cat CAT2 MIPI to RGB666 86-inch monitor with power-on driver

Overview

Based on the Taishanpai 4-inch 86-inch screen adapter - LCSC open-source hardware platform (oshwhub.com), modified
platform Wildfire Lubancat 2BTB version
MIPI DSI0
chip platform: RK3568

2024/08/19 Touch has been updated.
Different development boards have different DTSI, please pay attention to identification.
Example: I chose rk3568-lubancat-2io-dsi-800p.
Put the following content into the device tree:
&i2c1 {
status = "okay";
clock-frequency = ;
FT5X06@38 {
status = "okay";
compatible = "edt,edt-ft5406";
reg = ;

interrupt-parent = ;
interrupts
= ; reset_gpio = ;
wake_gpio=;
touchscreen-size-x = ;
touchscreen-size-y = ;
touch_type = ;
}; The device tree node directly calls the edt-ft5x06.c file without needing a patch
. Since it's unknown which makefiles Luban Cat uses , some defs are loaded for this driver, and other drivers are disabled. It's recommended to disable unnecessary models to improve compilation speed and prevent address errors and driver loading failures. # CONFIG_TOUCHSCREEN_GOODIX=y # CONFIG_TOUCHSCREEN_GSLX6801=y # CONFIG_TOUCHSCREEN_GSLX680_PAD=y # CONFIG_TOUCHSCREEN_GSLX680_VR=y # CONFIG_TOUCHSCREEN_GSL3673=y # CONFIG_TOUCHSCREEN_GSL3673_800X1280=y # CONFIG_TOUCHSCREEN_GSL3676=y # CONFIG_TOUCHSCREEN_HYN_CST2XX=y # CONFIG_TOUCHSCREEN_WACOM_W9013=y# CONFIG_TOUCHSCREEN_GT1X=y#CONFIG_TOUCHSCREEN_FTS=y#CONFIG_TOUCHSCREEN_ROCKPI_FT5406=yCONFIG_TOUCHSCREEN_EDT_FT5X06=y //86 screen driver# CONFIG_TOUCHSCREEN_CYPRESS_CYTTSP5=y# CONFIG_TOUCHSCREEN_CYPRESS_CYTTSP5_DEVICETREE_SUPPORT=y# CONFIG_TOUCHSCREEN_CYPRESS_CYTTSP5_I2C=y# CONFIG_TOUCHSCREEN_CYPRESS_CYTTSP5_DEVICE_ACCESS=y# Adding a # before CONFIG_TOUCHSCREEN_CYPRESS_CYTTSP5_LOADER=y indicates that I mainly modified lubancat2_android11_defconfig //This configuration file is most likely the one I compiled for MIPI800P .
