SN65DSI84: SN65DSI84 DSI to LVDS bridge porting issue on NXP Yocto i.MX8m mini

Hi Ti Support team,

I am using sn65dsi84 on nxp i.MX8m mini SOC with yocto platform, kernel 5.15.52.

There has ti-sn65dsi83.c driver in <kernel_root>/driver/gpu/drm/bridge which compatible with sn65dsi84 in kernel 5.15.52 opensource. 

And I'm facing some problem on bridge attach to DSI source like below error log:

[    2.329794] [drm:drm_bridge_attach] *ERROR* failed to attach bridge /soc@0/bus@32c00000/mipi_dsi@32e10000 to encoder DSI-34: -517

[    2.341480] imx_sec_dsim_drv 32e10000.mipi_dsi: Failed to attach bridge: 32e10000.mipi_dsi

[    2.349755] imx_sec_dsim_drv 32e10000.mipi_dsi: failed to bind sec dsim bridge: -517

I attached our bootlog, devicetree, sn65dsi84 register dump and our schematic as to_ti.zip for reference.

Many thanks!
