+Subject: [PATCH] bus: fsl-mc: Allocate mc-portal from root dprc container
+
+Root dprc container have allocate-able mc-portals which
+can be allocated by kernel drivers.
+
+As per current design mc-portal is allocated from parent
+dprc container if requesting device is not root-dprc.
+This works fine if the requesting device is child of
+root dprc container, because their parent is root-dprc
+container. But if request device is grandchild of root
+dprc container then it tries to allocate from it's parent
+root dprc-container and it fails.
