> The device firmware reports PTP clock capabilities to each PF during
> initialization. This includes various information for both the overall device and
> the individual function, including
> 
> For functions:
> * whether this function has timesync enabled
> * whether this function owns one of the 2 possible clock timers, and
>   which one
> * which timer the function is associated with
> * the clock frequency, if the device supports multiple clock frequencies
> * The GPIO pin association for the timer owned by this PF, if any
> 
> For the device:
> * Which PF owns timer 0, if any
> * Which PF owns timer 1, if any
> * whether timer 0 is enabled
> * whether timer 1 is enabled
> 
> Extract the bits from the capabilities information reported by firmware and
> store them in the device and function capability structures.o
> 
> This information will be used in a future change to have the function driver
> enable PTP hardware clock support.
