net: mscc: PTP Hardware Clock (PHC) support
This series introduces the PTP Hardware Clock (PHC) support to the Mscc
Ocelot switch driver. In order to make use of this, a new register bank
is added and described in the device tree, as well as a new interrupt.
The use this bank and interrupt was made optional in the driver for dt
compatibility reasons.
Thanks!
Antoine
Since v5:
- Made sure both the PTP interrupt and register bank were available to
enable supporting h/w timestamping.
- Added a check after a kzalloc.
- Add Reviewed-by tags from Andrew.
Since v4:
- Added SKBTX_IN_PROGRESS.
- Fixed two xmas trees.
- Rework the loop condition in ocelot_ptp_rdy_irq_handler.
Since v3:
- Fixed a spin_unlock_irqrestore issue.
Since v2:
- Prevented from a possible infinite loop when reading the h/w
timestamps.
- s/GFP_KERNEL/GFP_ATOMIC/ in the Tx path.
- Set rx_filter to HWTSTAMP_FILTER_PTP_V2_EVENT at probe.
- Fixed s/w timestamping dependencies.
- Added Paul Burton's Acked-by on patches 2 and 4.
Since v1:
- Used list_for_each_safe() in ocelot_deinit().
- Fixed a memory leak in ocelot_deinit() by calling
dev_kfree_skb_any().
- Fixed a locking issue in get_hwtimestamp().
- Handled the NULL case of ptp_clock_register().
- Added comments on optional dt properties.

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.
