DSIM uses MIC bridge which is between DECON and DSIM, so the driver
should expect bridge node on input side.

Hi Andrzej,

The of_graph_get_remote_node() does not exist in the kernel.
Also this patch  does not apply('git am') on drm-next tree.
Is this what you mean?
dsi->bridge_node = of_graph_get_endpoint_by_regs(node, DSI_PORT_IN, 0);
        if (!dsi->bridge_node)
                return -EINVAL;

Please check latest drm-next branch at git://people.freedesktop.org/~airlied/linux.git

Commit 86418f90a4c "drm: convert drivers to use of_graph_get_remote_node" got merged
via drm-misc tree and Andrzej's patch is a fix for it.

Best regards
