 From what I can tell from the documentation, this is sourced from 
ufs_unipro_core_clk_src, which is inturn sourced from gpll0_out_main. 
I'm guessing gcc-msm8998.c needs to be updated to reflect this.  It 
would also be good to check this against the downstream kernel.

Let me know if you want me to have a look at any other specific clocks.
