I am using the non-OS reference design of FMCOMMS1 on ML605.
I am very confused about the configuration on control registers and bit description of AD9523-1.
The "struct ad9523_platform_data ad9523_pdata_lpc" in AD9523_cfg.h
has the following lines. What does that mean?
In the reference design, it uses refb with 122.88MHz from AD9548, if pll1_feedback_div being 4, should not refb_r_div be set 4 as well?
