iMX8MM: MIPI DSI commands before enabling the CLK

Hi All,

a custom display manufacture requires receiving init commands before activating the clock.

If I try sending the commands during the panel_prepare function, I get the following kernel errors

   imx_sec_dsim_drv 32e10000.mipi_dsi: wait pkthdr tx done time out
   panel-simple-dsi 32e10000.mipi_dsi.0: Failed to send DCS (-16), (1)01
   imx_sec_dsim_drv 32e10000.mipi_dsi: panel prepare failed: -16

Is there any way to overcome the problem?

Thanks

Regards

Pier
