Other Parts Discussed in Thread: DSI-TUNER
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!
BS,
