7 title: Mediatek display merge
10 - Chun-Kuang Hu <chunkuang.hu@kernel.org>
11 - Philipp Zabel <p.zabel@pengutronix.de>
14 Mediatek display merge, namely MERGE, is used to merge two slice-per-line
15 inputs into one side-by-side output.
16 MERGE device node must be siblings to the central MMSYS_CONFIG node.
