The b53 has some implementation specific detail:
The b53 DSA driver tags the CPU port in all VLANs, since otherwise any
PVID untagged VLAN programming would basically change the CPU port's
default PVID and make it untagged, undesirable.
This need some attention while configuring. Therefore the configuration
is slightly different to the generic one:
The following extra commands are needed on b53 single port and gateway
configuration:
bridge vlan del dev lan1 vid 1
bridge vlan del dev lan2 vid 1
On bridge config the following commands are not needed:
bridge vlan add dev lan1 vid 1 pvid untagged
bridge vlan add dev lan2 vid 1 pvid untagged
bridge vlan add dev lan3 vid 1 pvid untagged

I like full configuration examples. But it can also be done by
describing the changes. I would prefer both - description and full
script:
...
Configuration without tagging support
-------------------------------------
Older models (5325, 5365) support a different tag format that is not
supported yet. 539x and 531x5 require managed mode and some special
handling, which is also not yet supported. The tagging support is
disabled in these cases and the switch need a different configuration.
The configuration slightly differ from
the :ref:`dsa-vlan-configuration`.
