Please don't. The board uses a THS8135, which has a few control signals.
They're not used on this board so you can certainly rely on the dumb-vga-dac
driver, but you should not use that compatible string. You should instead add
DT bindings for ti,ths8135 and add that compatible string to the dumb-vga-dac
driver.
The rest looks good to me.
