net: dsa: b53: add BCM63268 RGMII configuration

net: dsa: b53: Support setting learning on port

2021-02-23T20:23:00Z

Add support for being able to set the learning attribute on port, and make sure that the standalone ports start up with learning disabled. We can remove the code in bcm_sf2 that configured the ports learning attribute because we want the standalone ports to have learning disabled by default and port 7 cannot be bridged, so its learning attribute will not change past its initial configuration.

net: dsa: b53: b53_arl_rw_op() needs to select IVL or SVL

2020-04-22T19:50:41Z

Flip the IVL_SVL_SELECT bit correctly based on the VLAN enable status, the default is to perform Shared VLAN learning instead of Individual learning. Fixes: 1da6df85c6fb ("net: dsa: b53: Implement ARL add/del/dump operations") Signed-off-by: Florian Fainelli Signed-off-by: David S. Miller

net: dsa: b53: Rework ARL bin logic

2020-04-22T19:50:41Z

When asking the ARL to read a MAC address, we will get a number of bins returned in a single read. Out of those bins, there can essentially be 3 states: - all bins are full, we have no space left, and we can either replace an existing address or return that full condition - the MAC address was found, then we need to return its bin index and modify that one, and only that one - the MAC address was not found and we have a least one bin free, we use that bin index location then The code would unfortunately fail on all counts.

net: dsa: b53: Fix ARL register definitions

2020-04-22T19:50:41Z

The ARL {MAC,VID} tuple and the forward entry were off by 0x10 bytes, which means that when we read/wrote from/to ARL bin index 0, we were actually accessing the ARLA_RWCTRL register.

net: dsa: b53: Implement software reset for 58xx devices

2017-04-24T22:28:56Z

Implement the correct software reset sequence for 58xx devices by setting all 3 reset bits and polling for the SW_RST bit to clear itself without a given timeout. We cannot use is58xx() here because that would also include the 7445/7278 Starfighter 2 which have their own driver doing the reset earlier on due to the HW specific integration.

net: dsa: b53: Include IMP/CPU port in dumb forwarding mode

2017-04-24T22:28:56Z

Since Broadcom tags are not enabled in b53 (DSA_PROTO_TAG_NONE), we need to make sure that the IMP/CPU port is included in the forwarding decision. Without this change, switching between non-management ports would work, but not between management ports and non-management ports thus breaking the default state in which DSA switch are brought up.
