We are using ti 954/953 serdes, but we can't make the image output normally.
we use 954/953 sync mode by STP cable with below settings, but the mipi csi output from 954 is abnormal,
we can we only get the csi data output but without the csi clock.
please help to check what's wrong,
thanks

Initial steps,
1. ti954_reset
2. ti954_init
3. ti953_init
4. Sensor Init
5. ti954_enable
