2022-07-28can: can327: add software tx timestampsVincent Mailhol1-0/+2
TX timestamps were added to the can_put_echo_skb() function of can_dev modules in [1]. However, can327 does not rely on that function and as such does not offer TX timestamping. Add a call to skb_tx_timestamp() in the can327_netdev_start_xmit() function so that the module now supports TX software timestamps.

2022-07-28can: slcan: change every `slc' occurrence in `slcan'Dario Binacchi1-53/+56
In the driver there are parts of code where the prefix `slc' is used and others where the prefix `slcan' is used instead. The patch replaces every occurrence of `slc' with `slcan', except for the netdev functions where, to avoid compilation conflicts, it was necessary to replace `slc' with `slcan_netdev'. The patch does not make any functional changes.

2022-07-28can: slcan: remove legacy infrastructureDario Binacchi1-255/+63
Taking inspiration from the drivers/net/can/can327.c driver and at the suggestion of its author Max Staudt, I removed legacy stuff like `SLCAN_MAGIC' and `slcan_devs' resulting in simplification of the code and its maintainability. The use of slcan_devs is derived from a very old kernel, since slip.c is about 30 years old, so today's kernel allows us to remove it. The .hangup() ldisc function, which only called the ldisc .close(), has been removed since the ldisc layer calls .close() in a good place anyway. The old slcanX name has been dropped in order to use the standard canX interface naming. The ioctl SIOCGIFNAME can be used to query the name of the created interface. Furthermore, there are several ways to get stable interfaces names in user space, e.g. udev or systemd-networkd. The `maxdev' module parameter has also been removed.

As lately recommended in the mailing list[1], set the clock to zero time as part of initialization. The idea is that when the clock reads 'Jan 1, 1970', then it is clearly wrong and user will not mistakenly think that the clock is set correctly. If as part of initialization, the driver sets the clock, user might see correct date and time (maybe with a small shift) and assume that there is no need to sync the clock.

2022-07-25mlxsw: spectrum: Fix the shift of FID field in TX headerDanielle Ratson1-1/+1
Currently, the field FID in TX header is defined, but is not used as it is relevant only for data packets. mlxsw driver currently sends all host-generated traffic as control packets and not as data packets. In Spectrum-2 and Spectrum-3, the correction field of PTP packets which are sent as control packets is not updated at egress port. To overcome this limitation while adding support for PTP, some packets will be sent as data packets. Fix the wrong shift in the definition, to allow using the field later.

2022-07-25mlxsw: Set time stamp type as part of config profileDanielle Ratson4-1/+38
The type of time stamp field in the CQE is configured via the CONFIG_PROFILE command during driver initialization. Add the definition of the relevant fields to the command's payload and set the type to UTC for Spectrum-2 and above. This configuration can be done as part of the preparations to PTP support, as the type of the time stamp will not break any existing behavior.

2022-07-25mlxsw: reg: Add Monitoring Time Precision Correction Port Configuration RegisterDanielle Ratson1-0/+62
In Spectrum-2, all the packets are time stamped, the MTPCPC register is used to configure the types of packets that will adjust the correction field and which port will trap PTP packets. If ingress correction is set on a port for a given packet type, then when such a packet is received via the port, the current time stamp is subtracted from the correction field. If egress correction is set on a port for a given packet type, then when such a packet is transmitted via the port, the current time stamp is added to the correction field. Assuming the systems is configured correctly, the above means that the correction field will contain the transient delay between the ports. Add this register for a future use in order to support PTP in Spectrum-2.

2022-07-25net: macb: Update tsu clk usage in runtime suspend/resume for VersalHarini Katakam2-2/+16
On Versal TSU clock cannot be disabled irrespective of whether PTP is used. Hence introduce a new Versal config structure with a "need tsu" caps flag and check the same in runtime_suspend/resume before cutting off clocks. More information on this for future reference: This is an IP limitation on versions 1p11 and 1p12 when Qbv is enabled (See designcfg1, bit 3). However it is better to rely on an SoC specific check rather than the IP version because tsu clk property itself may not represent actual HW tsu clock on some chip designs.
