My rgb lcd screen does not display。
My board is based on the STM32MP153AAA3 design, using a separate power supply.
This is my schematic diagram
This is the timing of the LCD
This is the LCD device tree
This is some panel-simple driver code
Here are some boot logs
Looking forward to your response!

i have solved it.
The ltdc node has a problem:
<dc {
pinctrl-names = "default", "sleep";
status = "okay";
pinctrl-0 = <<dc_pins_b>;
pinctrl-1 = <<dc_pins_sleep_b>;
port {
#address-cells = <1>;
#size-cells = <0>;
ltdc_ep0_out: endpoint@0 {
reg = <0>;
remote-endpoint = <&rgb_8_panel_in>;
};
};
};
