7   This patch set introduces support for IEEE 1588 PTP clocks in
10   programs, synchronizing Linux with external clocks, and using the
11   ancillary features of PTP hardware clocks.
18     - Set time
19     - Get time
20     - Shift the clock by a given offset atomically
21     - Adjust clock frequency
24     - Time stamp external events
25     - Period output signals configurable from user space
26     - Low Pass Filter (LPF) access from user space
27     - Synchronization of the Linux system time via the PPS subsystem
65    ancillary feature, then the driver should just return -EOPNOTSUPP
81      - 2 Time stamp external triggers, programmable polarity (opt. interrupt)
82      - 2 Alarm registers (optional interrupt)
83      - 3 Periodic signals (optional interrupt)
87      - 6 GPIOs programmable as inputs or outputs
88      - 6 GPIOs with dedicated functions (LED/JTAG/clock) can also be
90      - GPIO inputs can time stamp external triggers
91      - GPIO outputs can produce periodic signals
92      - 1 interrupt pin
96      - Auxiliary Slave/Master Mode Snapshot (optional interrupt)
97      - Target Time (optional interrupt)
101      - Up to 4 independent PHC channels
102      - Integrated low pass filter (LPF), access via .adjPhase (compliant to ITU-T G.8273.2)
103      - Programmable output periodic signals
104      - Programmable inputs can time stamp external triggers
105      - Driver and/or hardware configuration through firmware (idtcm.bin)
106 …- LPF settings (bandwidth, phase limiting, automatic holdover, physical layer assist (per ITU-T G.…
107 …- Programmable output PTP clocks, any frequency up to 1GHz (to other PHY/MAC time stampers, refclk…
108 …       - Lock to GNSS input, automatic switching between GNSS and user-space PHC control (optional)
