In commitd687e056a1("soc: mediatek: mmsys: Add mt8192 mmsys routing table"), the mmsys routing table for mt8192 was introduced but the input selector for DITHER->DSI0 has no value assigned to it. This means that we are clearing bit 0 instead of setting it, blocking communication between these two blocks; due to that, any display that is connected to DSI0 will not work, as no data will go through. The effect of that issue is that, during bootup, the DRM will block for some time, while atomically waiting for a vblank that never happens; later, the situation doesn't get better, leaving the display in a non-functional state. To fix this issue, fix the route entry in the table by assigning the dither input selector to MT8192_DISP_DSI0_SEL_IN.
