Not all HW will be able to do bypass on all color
operations. Introduce an 'allow_bypass' boolean for
all colorop init functions and only create the BYPASS
property when it's true.

You did not change the documentation of struct drm_colorop_state, so can 
we expect state->bypass to be always valid (ie. false when bypass is not 
possible)?

I don't think so, because drm_atomic_helper_colorop_duplicate_state 
/ drm_colorop_reset are setting the bypass to true. Maybe you can add 
something like this?

	/**
	 * @bypass:
	 *
	 * When the property BYPASS exists on this colorop, this stores 
	 * the requested bypass state: true if colorop shall be bypassed, 
	 * false if colorop is enabled.
	 */
