2019-02-23net: dsa: mv88e6xxx: Fix -Wformat-security warningsFlorian Fainelli
We are not specifying an explicit format argument but instead passing a string litteral which causes these two warnings to show up: drivers/net/dsa/mv88e6xxx/chip.c: In function 'mv88e6xxx_irq_poll_setup': drivers/net/dsa/mv88e6xxx/chip.c:483:2: warning: format not a string literal and no format arguments [-Wformat-security] chip->kworker = kthread_create_worker(0, dev_name(chip->dev)); ^~~~ drivers/net/dsa/mv88e6xxx/ptp.c: In function 'mv88e6xxx_ptp_setup': drivers/net/dsa/mv88e6xxx/ptp.c:403:4: warning: format not a string literal and no format arguments [-Wformat-security] dev_name(chip->dev)); ^~~~~~~~ LD [M] drivers/net/dsa/mv88e6xxx/mv88e6xxx.o Signed-off-by: Florian Fainelli <f.fainelli@gmail.com> Reviewed-by: Andrew Lunn <andrew@lunn.ch> Signed-off-by: David S.

2018-07-18net: dsa: mv88e6xxx: Add hwtimestamp support for the 6165Andrew Lunn
The 6165 family supports a more restricted version of hardware time stamps. Only L2 PTP is supported. All ports have to use the same EtherType, and transport spec configuration. PTP can only be enabled/disabled globally, not per port. Signed-off-by: Andrew Lunn <andrew@lunn.ch> Acked-by: Richard Cochran <richardcochran@gmail.com> Signed-off-by: David S.

2018-07-18net: dsa: mv88e6xxx: Abstract supported PTP filtersAndrew Lunn
The 6165 only supports layer L2 PTP, where as the more modern devices also support UDP and UDPv6, i.e. L4. Abstract the supported receive filters. Signed-off-by: Andrew Lunn <andrew@lunn.ch> Acked-by: Richard Cochran <richardcochran@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2018-07-18net: dsa: mv88e6xxx: Abstract HW timestamp setupAndrew Lunn
The 6165 family does not have per port PTP control registers. Also, it places the timestamp data in different registers. Abstract the current implementation of 6352 compatible PTP devices so that 6165 can be added.

2018-07-18net: dsa: mv88e6xxx: Add mv88e6165 PTP supportAndrew Lunn
The mv88e6165 family has its global clock in the PTP global registers. It does not support any form of PTP events. Add a function to read the clock, fill in an ops structure, and register it with the two members of the family.

2018-07-18net: dsa: mv88e6xxx: Abstract PTP operationsAndrew Lunn
The mv88e6165 family supports PTP, but its registers use a different layout to the currently supported devices. Abstract accessing the PTP registers into a set of ops, so making space for a second implementation.

2018-02-14net: dsa: mv88e6xxx: add rx/tx timestamping supportBrandon Streiff
This patch implements RX/TX timestamping support. The Marvell PTP hardware supports RX timestamping individual message types, but for simplicity we only support the EVENT receive filter since few if any clients bother with the more specific filter types. checkpatch and reverse Christmas tree changes by Andrew Lunn. Re-factor duplicated code paths and avoid IfOk anti-pattern, use the common ptp worker thread from the class layer and time stamp UDP/IPv4 frames as well as Layer-2 frame by Richard Cochran.

2018-02-14net: dsa: mv88e6xxx: add support for event captureBrandon Streiff
This patch adds support for configuring mv88e6xxx GPIO lines as PTP pins, so that they may be used for time stamping external events or for periodic output. Checkpatch and reverse Christmas tree fixes by Andrew Lunn Periodic output removed by Richard Cochran, until a better abstraction of a VCO is added to Linux in general.

2018-02-14net: dsa: mv88e6xxx: expose switch time as a PTP hardware clockBrandon Streiff
