The clk framework should work fine if the returned clock is NULL (which
I think is your case).
The driver gates clocks when the device is suspended and on Intel LPSS

The current driver uses input clock source frequency to calculate
values for [SS|FS]_[HC|LC] registers. However, when booting ACPI, we do not
currently have a good way to provide the frequency information.
Instead, we can leverage the SSCN and FFCN ACPI methods, which can be used
to directly provid
