From: Andy Yan <andy.yan@xxxxxxxxxxxxxx> The port mux bits of VP2 should be defined by RK3568_OVL_PORT_SET__PORT2_MUX, this maybe a copy and paste error when this driver first introduced. Hi Heiko: Maybe thi is the problem you met when you porting the dsi2 driver. I previously sent you this patch when you ask me about this issue on email,but I'm not sure if you received it.
