integrating Riverdi MIPI Display in imx93 custom board

bplc123

Experts,

We have been trying to integrate Riverdi RVT101HVDNWC00-B mipi display with imx93 custom board. The driver ti-SN65DSI83 and touch driver of ilitech has been enabled in kernel. But the display is not probing in the board. Hereby attaching the dts snippet and error log in the same file. Please suggest any alternatives or changes to be done.

Thanks in advance

After changing the driver of ti-sn65dsi83.c, I have moved the host attach function. ow with i2cdetect I can see 2c address registered and detected. But the display is still not coming. In the log, I can see,

dmesg | grep dsi

It would be helpful if any further steps are provided

Hi @bplc123,

We use that display in our BSP but for iMX95.

You can see the proper device tree configuration in the links below:
