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.
