PS5, Line 13: disabling this feature results in 110 mW power savings
> Hi Subrata,

> Yes your observation from previous generations is correct. But in ADLP this feature is not working as expected and hence needs to be disabled to avoid PnP impact. We found that C1stateAutodemotion feature is not supported for ADLP SKUs, so default option is for it to be disabled. Hence keeping it disabled.

Thanks Vinay for sharing the details, Can you please update the commit msg to reflect "C1stateAutodemotion" is not applicable for ADL and future generation SoC platform ?
