Subject: [PATCH net-next v3 0/8] net: mscc: PTP Hardware Clock (PHC) support
Date: Wed, 24 Jul 2019 10:17:07 +0200 [thread overview]
Message-ID: <20190724081715.29159-1-antoine.tenart@bootlin.com> (raw)
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 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.
