Hi Angelo,

The problem with this is that you need DDP_COMPONENT_DRM_OVL_ADAPTOR... which is
a software thing and not HW, so that can't be described in devicetree.
The only thing this series won't deal with is exactly that.
Sorry, no, I got confused.
The series *does* already deal with that, as the pipeline is built before the check
for OVL_ADAPTOR components, so that will get probed.
Are you sure? Because who is actually adding the OVL_ADAPTOR to the
path? It looks like your patch will walk the graph and add all the
components according to their compatible string. And since the
OVL_ADAPTOR is virtual and doesn't have a node..
I shouldn't look at code while having a flu.
if (mtk_drm_find_mmsys_comp(private, DDP_COMPONENT_DRM_OVL_ADAPTOR)) {
...but yes nothing adds the mmsys_comp for OVL_ADAPTOR.
Needs to be addressed, will do that asap.
