Subject: [PATCH net-next 0/3] ptp: Add adjust phase to support phase offset.
Date: Wed, 29 Apr 2020 20:28:22 -0400 [thread overview]
Message-ID: <1588206505-21773-1-git-send-email-vincent.cheng.xh@renesas.com> (raw)
From: Vincent Cheng <vincent.cheng.xh@renesas.com>
This series adds adjust phase to the PTP Hardware Clock device interface.
Some PTP hardware clocks have a write phase mode that has
a built-in hardware filtering capability. The write phase mode
utilizes a phase offset control word instead of a frequency offset
control word. Add adjust phase function to take advantage of this
capability.
Vincent Cheng (3):
ptp: Add adjphase function to support phase offset control.
ptp: Add adjust_phase to ptp_clock_caps capability.
ptp: ptp_clockmatrix: Add adjphase() to support PHC write phase mode.
