[PATCH v6, 14/14] drm/mediatek: add support for mediatek SOC MT8183

Yongqiang Niu
2020-01-02T04:14:52Z

This patch add support for mediatek SOC MT8183
1.ovl_2l share driver with ovl
2.rdma1 share drive with rdma0, but fifo size is different
3.add mt8183 mutex private data, and mmsys private data
4.add mt8183 main and external path module for crtc create
