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 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.
