As i can see, in the imx-regs.h for the different processors there is
(as the name says) only definitions and structures for the internal
registers of each processor. No function prototypes.

What about to move the prototype ? For MX5/MX35 there is a sys_proto.h
(as it is done for other SOCs), in this case, well, it seems too much to
add a file for a single line. However, we could move it in clock.h and
creating a sys_proto.h if the number of exported functions will increase.

Best regards,
Stefano Babic
