I am porting a mipi driver on IMX93, but I encountered some issues with the device tree,
a.The original device tree is as follows, and I directly added it to my IMX8MQ, changed its name, and commented out some pins;
Firstly, how can we determine which controller mipi_dsi has been connected to and its relationship?
b.Is it possible for the following error to occur due to the device tree? IMX DRM display subsystem: No available ports, how should we investigate?
c.What is the difference between placing the port keyword in the "device tree" on the same node and different nodes? For example, the following two screenshots;
d. According to the "schematic" or "device tree" description, if the device tree is a reference to a name, how can the "association relationship" of the device tree be identified?
Thank you very much!
The MIPI name in i.MX93 is dsi, not mipi_dsi_bridge.
If you want to port new dsi panel, please refer arch/arm64/boot/dts/freescale/imx93-11x11-evk-rm67199.dts. Do not include your settings about i.MX8MQ.
