Yes, DIGCTRL_CTRL is still not defined.
So for conveniently I just used DIGCTRL_BASE_ADDR.
I'm going to add it in digctl.h.
If it's not the right place please let me know.

How do you suggest to separate?
All changes are mainly to add saif pdata.
You mean to move DIGCTL related saif pdata function to another patch?
