PS22, Line 297: 	port_bitmask = ops->dp_ops.wait_for_connection(WAIT_FOR_DISPLAYPORT_TIMEOUT_MS);
suggestion: after getting `ops`, return early if ops is NULL

PS22, Line 331: if (ret)
              : 			printk(BIOS_ERR, "Port C%zd mux set failed with error %d\n", i, ret);
              : 		else {
              : 			printk(BIOS_INFO, "Port C%zd is configured to DP mode!\n", i);
              : 			return;
              : 		}
style: if one arm of a conditional requires braces, then all branches should have them
