For the i.MX8MM only support the MIPI DSI, we have the MIPI DSI to HDMI board connect to the EVK board.

 You can see the display , you do not need to disable it:

&mipi_dsi {
status = "okay";
 
port@1 {
dsim_to_adv7535: endpoint {
remote-endpoint = <&adv7535_from_dsim>;
attach-bridge;
};
};
};
in the imx8mm-evk.dtsi.
For MIPI DSI to LVDS display you need to modify the remote-endpoint.
And configure the adv_bridge according to your dsiplay:
adv_bridge: adv7535@3d {
compatible = "adi,adv7533";
reg = <0x3d>;
adi,addr-cec = <0x3b>;
adi,dsi-lanes = <4>;
pinctrl-names = "default";
pinctrl-0 = <&pinctrl_i2c2_synaptics_dsx_io>;
interrupt-parent = <&gpio1>;
interrupts = <9 IRQ_TYPE_LEVEL_LOW>;
 
status = "okay";
 
port {
adv7535_from_dsim: endpoint {
remote-endpoint = <&dsim_to_adv7535>;
};
};
};

I have attached my function below.

-> Why attach-bridge is used is used in mipi-dsi function inside port1.

-> Should i replace my my lvds to port 1 or its fine in port 2 also

I have attached screenshot of i2c detect

i have added sn65dsi83 driver in i2c detect for prebuild image i am able to see the slave address 2c. after added the fuction in dts and driver file .

It shows as UU.

-> what is the difference between display slave address and display UU.

I have added driver folder below

-> I have only edited in .dts file and added driver. Should i even edit in any other file also.

And should i config in drm/panel any files in panel folder tomatch to the display or only in .dts file is enough.

Kindly address to every question above.

Thanks and Regards

Ruban
