While I am at it, this machine driver uses .ignore_pmdown_time, which is typically used to avoid clock issues. Now that you have an explicit control on clocks, is .ignore_pmdown_time actually required?

This function call prevents the clk_set_rate() from being called when clock is enabled. It's removed during the upstream review and use the flag CLK_SET_RATE_GATE instead. Will fix it.

While I am at it, this machine driver uses .ignore_pmdown_time, which is typically used to avoid clock issues. Now that you have an explicit control on clocks, is .ignore_pmdown_time actually required?
Actually I don't know the purpose to use ignore_pmdown_time flag in the first place but I think they are not related since this patch is to turn on ssp clocks earlier while the ignore_pmdown_time flag is used to delay the DAPM power down for playback stream in the soc_pcm_close(). Just my two cents and thank you for the review.

Hi Pierre-Louis
This is the v2 patch based on your previous comment to remove unnecessary function calls. The order in Kconfig is also rearranged. Please let me know if this patch is ok. Thanks.
I don't see a v2?
