iMX8QM 8-lane MIPI DSI to FPD-Link

jsmith8831 — Thu, 22 Aug 2024 16:38:26 GMT

Hello,

I would like to use 2x MIPI DSI ports (8-lanes) to drive a LCD, 4-lanes of odd data, 4-lanes of even data. According to the post in the link below, the iMX8QM does support this. Is there a device tree example of how to achieve this using both DSI ports together?

In the mipi-dsi-bus.txt file in the device tree binding documentation folder, I see this mentioned, but I am unsure how to use this:

Optional properties: - clock-master: boolean. Should be enabled if the host is being used in conjunction with another DSI host to drive the same peripheral. Hardware supporting such a configuration generally requires the data on both the busses to be driven by the same clock. Only the DSI host instance controlling this clock should contain this property.

Hello,

With current device tree you can check two mipi at the time you don't need to change anything.
