DSIM uses MIC bridge which is between DECON and DSIM, so the driver

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
