Hi,
I've just sent "net: dsa: populate supported_interfaces member"
which adds a hook to allow DSA to populate the newly introduced
supported_interfaces member of phylink_config. Once this patch is
merged, it would be great to see any new drivers setting this
member.
Essentially, the phylink_get_interfaces method is called with the
DSA switch and port number, and a pointer to the supported_interfaces
member - which is a bitmap of PHY_INTERFACE_MODEs that are supported
by this port.
When you have set any bit in the supported interfaces, phylink's
behaviour when calling your lan937x_phylink_validate changes - it will
no longer call it with PHY_INTERFACE_MODE_NA, but will instead do a
bitwalk over the bitmap, and call it for each supported interface type
instead.
When phylink has a specific interface mode, it will continue to make a
single call - but only if the interface mode is indicated as supported
in the supported interfaces bitmap.
Please keep an eye on "net: dsa: populate supported_interfaces member"
and if you need to respin this series after that patch has been merged,
please update in regards of this.
Thanks.
