Merge branch 'ptp-adjphase-cleanups'
Rahul Rameshbabu says:
====================
ptp .adjphase cleanups
The goal of this patch series is to improve documentation of .adjphase, add
a new callback .getmaxphase to enable advertising the max phase offset a
device PHC can support, and support invoking .adjphase from the testptp
kselftest.
Changes:
v2->v1:
* Removes arbitrary rule that the PHC servo must restore the frequency
to the value used in the last .adjfine call if any other PHC
operation is used after a .adjphase operation.
* Removes a macro introduced in v1 for adding PTP sysfs device
attribute nodes using a callback for populating the data.
