...can we rename the flags to more meaningful names instead?

	unsigned clk_pol_rising_edge:1;

	unsigned hsync_active_high:1;
	unsigned vsync_active_high:1;

Now look at patch 7, where these become tri-state:
- don't change
- rising edge/active high
- falling edge/active low

So your suggestion is not a good idea.

Hm, you're right.

Still I think we should add a prefix to make the context of the flags
clear.
