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.
