e85a96e48e net: lan966x: Add support for ptp interrupts
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.

77eecf25bd net: lan966x: Update extraction/injection for timestamping
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.

735fec995b net: lan966x: Implement SIOCSHWTSTAMP and SIOCGHWTSTAMP
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.

d096459494 net: lan966x: Add support for ptp clocks
The lan966x has 3 PHC. Enable each of them, for now all the
timestamping is happening on the first PHC.

7aacb894b1 net: lan966x: Extend switchdev with mdb support
Extend lan966x driver with mdb support by implementing the switchdev
calls: SWITCHDEV_OBJ_ID_PORT_MDB and SWITCHDEV_OBJ_ID_HOST_MDB.
It is allowed to add both ipv4/ipv6 entries and l2 entries. To add
ipv4/ipv6 entries is not required to use the PGID table while for l2
entries it is required. The PGID table is much smaller than MAC table
so only fewer l2 entries can be added.

11b0a27772 net: lan966x: Add PGID_GP_START and PGID_GP_END
The first entries in the PGID table are used by the front ports while
the last entries are used for different purposes like flooding mask,
copy to CPU, etc. So add these macros to define which entries can be
used for general purpose.

fc0c3fe748 net: lan966x: Add function lan966x_mac_ip_learn()
Extend mac functionality with the function lan966x_mac_ip_learn. This
function adds an entry in the MAC table for IP multicast addresses.
These entries can copy a frame to the CPU but also can forward on the
front ports.
This functionality is needed for mdb support. In case the CPU and some
of the front ports subscribe to an IP multicast address.

cf2f60897e net: lan966x: Add support to offload the forwarding.
This patch adds basic support to offload in the HW the forwarding of the
frames. The driver registers to the switchdev callbacks and implements
the callbacks for attributes SWITCHDEV_ATTR_ID_PORT_STP_STATE and
SWITCHDEV_ATTR_ID_BRIDGE_AGEING_TIME.
It is not allowed to add a lan966x port to a bridge that contains a
different interface than lan966x.

5ccd66e01c net: lan966x: add support for interrupts from analyzer
This patch adds support for handling the interrupts generated by the
analyzer. Currently, only the MAC table generates these interrupts.
The MAC table will generate an interrupt whenever it learns or forgets
an entry in the table. It is the SW responsibility figure out which
entries were added/removed.
