> Add the ice_ptp_hw.c file and some associated definitions to the ice driver
> folder. This file contains basic low level definitions for functions that interact
> with the device hardware.
>
> For now, only E810-based devices are supported. The ice hardware supports
> 2 major variants which have different PHYs with different procedures
> necessary for interacting with the device clock.
>
> Because the device captures timestamps in the PHY, each PHY has its own
> internal timer. The timers are synchronized in hardware by first preparing the
> source timer and the PHY timer shadow registers, and then issuing a
> synchronization command. This ensures that both the source timer and PHY
> timers are programmed simultaneously. The timers themselves are all driven
> from the same oscillator source.
>
> The functions in ice_ptp_hw.c abstract over the differences between how
> the PHYs in E810 are programmed vs how the PHYs in E822 devices are
> programmed. This series only implements E810 support, but E822 support will
> be added in a future change.
