same for these 2 ... should be part of the pll addition itself
  };
Done.
Sorry, I have one question:
The "struct rockchip_pll_rate_table" is called in "rockchip/clk-pll.c" 
on many functions, I think I could add a struct like:
struct rk3036_pll_rate_table {
     unsigned int fbdiv;
     unsigned int postdiv1;
     unsigned int refdiv;
     unsigned int postdiv2;
     unsigned int dsmpd;
     unsigned int frac;
};
but, it will add many redundancy codes in "rockchip/clk-pll.c" just for 
call "struct rk3036_pll_rate_table".

Thanks.
