Hi,

I tried to add a new panel in i.MX8M Mini with ST7701 controller on Yocto kernel 5.4.47. I got error "imx_sec_dsim_drv 32e10000.mipi_dsi: Failed to attach bridge: 32e10000.mipi_dsi"

After that probe completed successfully with sending init sequence. I can also confirm fbset on board, but can not see anything on display.

Can you please guide me how to solve the issue?
Any help will be appreciated.

Thanks
