I have some issues with the LCD with the kernel 4.19
I updated panel-simple.c as instructed by TI to another customer who seem to have a similar issue.
I don't know what could be wrong. It looks like something is on the LCD but no command line text or weston display
I put ---------------------------------- between each block to make it easier to follow
Here is the original devicetree information for the 12 inch display
lcd0: display {
compatible = "panel-dpi";
label = "lcd0";
backlight = <&lcd_bl>;
panel-timing {
clock-frequency = <93688800>;
hactive = <1920>;
vactive = <720>;
hfront-porch = <115>;
hback-porch = <20>;
hsync-len = <5>;
vback-porch = <3>;
vfront-porch = <32>;
vsync-len = <3>;
hsync-active = <0>;
vsync-active = <0>;
de-active = <1>;
pixelclk-active = <1>;
};
port {
lcd_in: endpoint {
remote-endpoint = <&dpi_out>;
};
};
};
------------------------------------------------------------------------------------------------------------------------
Here is the device tree change and panel-simple.c changes

lcd0: display {
