Do you mean joystick, or gamepad such as the 360/xbox1 controller? as far as a joystick goes I'm surprised you could use it with any games on Origin. If you mean gamepad, then You'll be able to use it at the very least with the dragon age games, mass effect titles, the racing/sports games, and possibly the single player but defiantly not the multiplayer for any of the first person shooters. You can also use it with games such as the witcher3 and many other titles on origin. That should be about it, even then in most cases you're much better off using a mouse and keyboard. You also shouldn't be demanding a full list anyways, Just google search if the game you want is on the xbox360/xbox1 and there you have it you'll be able to use your gamepad, if it's not on an xbox you're probably better off without it anyways.
That having been said.
1:you're on a pc if you wanna use a gamepad go ahead, but trust me learn to use a mouse and keyboard. If you're on pc and not using mouse and keyboard then you're making things harder on yourself.
2: for the first person shooters battlefield if you can use the you'll only be able to use it for the single player portion of the game not the multiplayer.
