[PATCH 3/3] media: mtk-mdp: Fix mdp device tree

From: Minghsiu Tsai
Date: Thu Apr 13 2017 - 03:33:23 EST


From: Daniel Kurtz <djkurtz@xxxxxxxxxxxx>

If the mdp_* nodes are under an mdp sub-node, their corresponding
platform device does not automatically get its iommu assigned properly.

Fix this by moving the mdp component nodes up a level such that they are
siblings of mdp and all other SoC subsystems. This also simplifies the
device tree.
