I know at my school, a lot of the CS or computer engineer students take a good chunk of physics for their major: Newtonian Mechanics, Electrodynamics, Thermodynamics, Quantum and Optics, but just enough to get the idea of how it works. The physics majors then take those classes again in much more detail. I would stick with CS if that's what you enjoy the most so you can have the luxury of learning the physics while sticking to the major you want.
