Radu Pirea says: ==================== Add PTP support for TJA1103 This is the PTP support for TJA1103. The RX timestamp is found in the reserved2 field of the PTP package. The TX timestamp has to be read from the phy registers. Reading of the timestamp works with interrupts or with polling(that starts when .nxp_c45_txtstamp is called). The implementation of .adjtime is done by read modify write because there is no way to atomically add/subtract a constant from the clock value. I've moved scaled_ppm_to_ppb function from ptp_clock.c to ptp_clock_kernel.h in order to be able to build the driver without PTP_1588_CLOCK=y. ==================== Signed-off-by: David S.

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.
