The ETM0700G0DH6 Datasheet lists 2 lines as the typical vsync pulse
width, 525 lines as the vertical period, and 35 lines as the vsync -de
time, which is vsync len + back porch.
So vertical timings 480 + 10 + 2 + 33 = 525 should be valid for the
ET0700G0DH6 panel:

et070080dh6

I have not seen the data sheet for ET070080DH6.
