The current driver only enables Pdelay_Req and Pdelay_Resp when HWTSTAMP_FILTER_PTP_V2_EVENT, HWTSTAMP_FILTER_PTP_V1_L4_EVENT or HWTSTAMP_FILTER_PTP_V2_L4_EVENT is requested. This results in ptp sync on slave mode to report 'received SYNC without timestamp' when using ptp4l. Although the hardware can support Sync, Pdelay_Req and Pdelay_resp by setting bit14 annd bits 17/16 to 01 this leaves Delay_Req timestamps out. Fix this by enabling all event and general messages timestamps. This includes SYNC, Follow_Up, Delay_Req, Delay_Resp, Pdelay_Req, Pdelay_Resp and Pdelay_Resp_Follow_Up messages.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
