dts: Adding device tree for drm panel

[Jaimin19parmar]

Panel: raspberry pi 7-inch display DSI connection two-lane Configurable through i2c

My changes:

1. Adding port in mdss_dsi0 node. ` ports { port@0 { reg = <0>; mdss_dsi0_out: endpoint { remote-endpoint = <&mdss_dsi0_in>; }; }; };

`

2. Adding Panel configuration. `&qupv3_se2_i2c { status = "ok"; qcom,clk-freq-out = <100000>; rpi-display@45 { status = "ok"; compatible = "raspberrypi,7inch-touchscreen-panel"; reg = <0x45>; port { mdss_dsi0_in: endpoint { remote-endpoint = <&mdss_dsi0_out>; }; }; };

   rpi-touchscreen@38 {
           status = "ok";
           compatible = "rpi,ft5406";
           reg = <0x38>;
           touchscreen-size-x = <800>;
           touchscreen-size-y = <480>;
           rotate_180 = <0>;
   };

}; --> Compilation successful without any warning or error. --> Gives runtime error.

Let me know possible causes. Thanks

Hi,

linux-mdss-dsi-panel-driver-generator allows generating display panel drivers for the "mainline"/"upstream" Linux kernel (taken directly from https://www.kernel.org/). It looks like you are using a modified "downstream" Linux kernel from Qualcomm. Please ask them (or whoever provided the kernel source to you) for help instead.

Thanks!
