Merge branch 'mlxsw-Spectrum-2-PTP-preparations'
Ido Schimmel says: ==================== mlxsw: Spectrum-2 PTP preparations This patchset includes various preparations required for Spectrum-2 PTP support. Most of the changes are non-functional (e.g., renaming, adding registers). The only intentional user visible change is in patch #10 where the PHC time is initialized to zero in accordance with the recommendation of the PTP maintainer. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
