Hi,
I am trying to use jdi-lt070me05000 (1200x1920 mipi dsi display) on i.mx8mq custom board.
I saw HDMI working fine with DCSS, but now I tried to enable the LCD mentioned above with DCSS (mipi dsi) referencing the "fsl-imx8mq-evk-dcss-rm67191.dts" file.
But here I am getting the error as below.

However, after that, all other prints will look correct, but the LCD will show nothing. Clock and power sequences are displayed as expected.
fbset command outputs as below.
