Yes, for us it would be better to have hifi_pll with predefined rate. For instance it will allow to avoid that ugly workaround in PDM (sysrate property, etc). But what whould be preferred for upstream? I can imagine a scenario where samples with different rate should be played, PDM attached to fclk_divN and there are no conflicts with TDM. In this case reconfiguration of hifi_pll on demand could better satisfy somebody's requirements. >> >> On 3/19/24 11:30, Jerome Brunet wrote: >>> >>> On Tue 19 Mar 2024 at 04:47, Jan Dakinevich wrote: >>> >>>> Let's start from the end: >>>> >>>>> No - Looks to me you just have two clock controllers you are trying >>>> force into one. >>>> >>>>> Again, this shows 2 devices.
