2022-03-15	net: sparx5: fix a couple warning messages	Dan Carpenter	1	-2/+2
	The WARN_ON() macro takes a condition, not a warning message. Fixes: 0933bd04047c ("net: sparx5: Add support for ptp clocks") Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com> Link: https://lore.kernel.org/r/20220314140327.GB30883@kili Signed-off-by: Paolo Abeni <pabeni@redhat.com>
2022-03-04	net: sparx5: Fix initialization of variables on stack	Horatiu Vultur	1	-2/+2
	The variables 'res' inside the functions sparx5_ptp_get_1ppm and sparx5_ptp_get_nominal_value was not initialized. So in case of the default case of the switch after, it would return an uninitialized variable. This makes also the clang builds to failed.

2022-03-04	net: sparx5: Add support for ptp interrupts	Horatiu Vultur	1	-0/+119
	When doing 2-step timestamping the HW will generate an interrupt when it managed to timestamp a frame. It is the SW responsibility to read it from the FIFO. Signed-off-by: Horatiu Vultur <horatiu.vultur@microchip.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2022-03-04	net: sparx5: Update extraction/injection for timestamping	Horatiu Vultur	1	-0/+166
	Update both the extraction and injection to do timestamping of the frames. The extraction is always doing the timestamping while for injection is doing the timestamping only if it is configured.

2022-03-04	net: sparx5: Implement SIOCSHWTSTAMP and SIOCGHWTSTAMP	Horatiu Vultur	1	-0/+74
	Implement the ioctl callbacks SIOCSHWTSTAMP and SIOCGHWTSTAMP to allow to configure the ports to enable/disable timestamping for TX. The RX timestamping is always enabled. The HW is capable to run both 1-step timestamping and 2-step timestamping. Signed-off-by: Horatiu Vultur <horatiu.vultur@microchip.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2022-03-04	net: sparx5: Add support for ptp clocks	Horatiu Vultur	1	-0/+326
	The sparx5 has 3 PHC. Enable each of them, for now all the timestamping is happening on the first PHC. Signed-off-by: Horatiu Vultur <horatiu.vultur@microchip.com> Signed-off-by: David S. Miller <davem@davemloft.net>
