Something that would describe the hardware is a property telling whether
the filter is present on VDD, not a property selecting DSM. The driver
can then chose to avoid standard mode when needed.

Something that would describe the hardware is a property telling whether
the filter is present on VDD, not a property selecting DSM. The driver
