The requirement for this came while adding runtime PM support for HDAI think you meant this: https://patchwork.ozlabs.org/patch/1031007/
driver. There were concerns about driver explicitly handling !PM case.
In general, drivers need to handle !PM case with work arounds for
managing clocks and power explicitly, which is not really necessary
when PM support on tegra is in good shape. In fact ARM 64-bit Tegra
platforms enforce PM support and there is no reason why this cannot be
done for 32-bit.
More details with regards to above can be found in following patch,
