On the IMx8MQ platform, I used 'memtool' to read the setting values of miPI DSI registers in the kernel and set the MIpi DSI in Uboot with these values. Now The problem I encountered was that I could not get a DPHY Lock.Now I set the clock register according to the registers of the kernel, and the printed clocks are as follows: DSI Core CLK =266M, DSI PHY ref CLK =22M, DSI ESC RX CLK =39M.In addition, I modified it with the framework of \drivers\video\mipi_dsi_northwest.What should I do to debug the MIPI signal in IMx8MQ Uboot?
