198 that will be moved around different displays.
204 the two displays, we need to use 2 pipes. See the example below where we avoid
208 - 2 displays (2 pipes) + MPO (1-2 pipes); we will use 4 pipes. MPO in the
209 middle of both displays needs 2 pipes.
210 - 3 Displays (3 pipes) + MPO (1-2 pipes), we need 5 pipes.
212 If we use MPO with multiple displays, the userspace has to decide to enable
213 multiple MPO by the price of limiting the number of external displays supported
