Subject: [PATCH 1/3] dt-bindings: mt8173: Fix mdp device tree
Date: Thu, 13 Apr 2017 15:33:05 +0800 [thread overview]
Message-ID: <1492068787-17838-2-git-send-email-minghsiu.tsai@mediatek.com> (raw)
In-Reply-To: <1492068787-17838-1-git-send-email-minghsiu.tsai@mediatek.com>
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.
