 Hi Paul,
 
 You were right, the hardware team has confirmed that, the VPFE master port is
 connected to L3 and the VPFE slave port is connected to L4. The L3 port cannot
 serve as a register target because it is initiator only.
 
 I have created links referring to dss l3/l4 hwmod and tested it, lemme know
 if I have missed something.
