Subject: [PATCH 3/3] media: mtk-mdp: Fix mdp device tree
Date: Thu, 13 Apr 2017 15:33:07 +0800	[thread overview]
Message-ID: <1492068787-17838-4-git-send-email-minghsiu.tsai@mediatek.com> (raw)
In-Reply-To: <1492068787-17838-1-git-send-email-minghsiu.tsai@mediatek.com>

From: Daniel Kurtz <djkurtz@chromium.org>

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.
