2022-11-11ptp_phc: convert .adjfreq to .adjfineJacob Keller1-15/+4
The ptp_phc implementation of .adjfreq is implemented in terms of a straight forward "base * ppb / 1 billion" calculation. Convert this to the newer .adjfine, updating the driver to use the recently introduced adjust_by_scaled_ppm helper function.

2020-06-25ptp_pch: use generic power managementVaibhav Gupta1-34/+3
With legacy PM, drivers themselves were responsible for managing the device's power states and takes care of register states. After upgrading to the generic structure, PCI core will take care of required tasks and drivers should do only device-specific operations. In the case of ptp_pch, after removing PCI helper functions, .suspend() and .resume() became empty-body functions. Hence, define them NULL and use dev_pm_ops. Compile-tested only.
