Thanks for your work. I would like to test this together with the DSIM 
and PHY driver by Michael and Marek. So far the boot hangs when probing 
the DSIM, but I'm not even sure if my DT is correct.

With the DSIM PHY driver (see [1]) in place, the GPR_MIPI_M_RESETN 
should be set correctly, right?

Would you mind sharing your imx8mm.dtsi, that you used for testing?

Thanks
Frieder
