[PATCH v1 1/2] dt-bindings: dma: mediatek: mark useless items as decrepted

From: Huihui Wang
Date: Thu Jul 16 2020 - 23:06:07 EST


From: huihui wang <huihui.wang@xxxxxxxxxxxx>

Because we move dma address bits config to mtk-uart-apdma.c,
it is unnecessary to be configured in device tree.
Update the document at the same time.
