[net-next,v2,0/8] net: mscc: PTP Hardware Clock (PHC) support

Hello,

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.

Patches 2 and 4 should probably go through the MIPS tree.

Thanks!
Antoine

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.
