Re: [PATCH v4 0/2] clk: qcom: Add support for RCG to register for DFS

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 

Hello Stephen,
Thanks for the changes, I have tested the changes and would require the change mentioned below for this to work.

  [v4]
   * Add recalc_clk_ops to calculate the clock frequency reading the current 
     perf state, also add CLK_GET_RATE_NOCACHE flag.
   * Cleanup 'goto' during mode check in 'clk_rcg2_calculate_freq'.
   * cleanup return from function 'com_cc_register_rcg_dfs'.


I want to squash this in. I have only compile tested it. Let me know
what you think.

This function would retrieve the parent_rate and if the parent_rate is not ready then it would fail to boot up.
So we have to make sure the parents are registered before these RCGs. That also was one reason for me to not populate the frequency table at recalc. 

We would need this patch to make this work.
