Subject: [PATCH net-next 0/9] mlxsw: Add support for physical hardware clock
Date: Mon, 3 Jun 2019 15:12:35 +0300 [thread overview]
Message-ID: <20190603121244.3398-1-idosch@idosch.org> (raw)
From: Ido Schimmel <idosch@mellanox.com>
This is the first of about four patchsets that add PTP support in mlxsw
for the Spectrum-1 ASIC.
This patchset exposes the physical hardware clock, while subsequent
patchsets will add timestamping support and mlxsw tracepoints for
debugging and testing.
Shalom says:
This patchset adds support for physical hardware clock for Spectrum-1
ASIC only.
Patches #1, #2 and #3 add the ability to query the free running clock
PCI address.
Patches #4 and #5 add two new register, the Management UTC Register and
the Management Pulse Per Second Register.
Patch #6 publishes scaled_ppm_to_ppb() to allow drivers to use it.
Patch #7 adds the physical hardware clock operations.
Patch #8 initializes the physical hardware clock.
Patch #9 adds a selftest for testing the PTP physical hardware clock.
Shalom Toledo (9):
mlxsw: cmd: Free running clock PCI BAR and offsets via query firmware
mlxsw: core: Add a new interface for reading the hardware free running
clock
mlxsw: pci: Query free running clock PCI BAR and offsets
mlxsw: reg: Add Management UTC Register
mlxsw: reg: Add Management Pulse Per Second Register
ptp: ptp_clock: Publish scaled_ppm_to_ppb
mlxsw: spectrum_ptp: Add implementation for physical hardware clock
operations
mlxsw: spectrum: PTP physical hardware clock initialization
selftests: ptp: Add Physical Hardware Clock test
