[PATCH RFC net-next 0/4] net: dsa: ocelot: phylink updates

From: "Russell King (Oracle)" <linux@armlinux.org.uk>
Date: 2022-02-25 14:34:27 

Hi,

This series updates the Ocelot DSA driver for some of the recent
phylink changes. Specifically, we fill in the supported_interfaces
fields, convert to mac_select_pcs and mark the driver as non-legacy.
We do not convert to phylink_generic_validate() as Ocelot has
special support for its rate adapting PCS which makes the generic
validate method unsuitable for this driver.

The three changes mentioned above are implemented in their own
separate patches with one additional cleanup:

1) Populate the supported_interfaces bitmap
2) Remove the now unnecessary interface checks in the validate methods
3) Convert from phylink_set_pcs() to .mac_select_pcs.
4) Mark the driver as non-legacy

Thanks.

[PATCH RFC net-next 1/4] net: dsa: ocelot: populate supported_interfaces

From: Russell King (Oracle) <hidden>
Date: 2022-02-25 14:35:27 

Populate the supported interfaces bitmap for the Ocelot DSA switches.

The felix_vsc9959 and seville_vsc9953 sub-drivers only supports a
single interface mode, defined by ocelot_port->phy_mode, so we indicate
only this interface mode to phylink.

[PATCH RFC net-next 2/4] net: dsa: ocelot: remove interface checks

From: Russell King (Oracle) <hidden>
Date: 2022-02-25 14:35:38 

When the supported interfaces bitmap is populated, phylink will itself
check that the interface mode is present in this bitmap. Drivers no
longer need to perform this check themselves. Remove these checks.

[PATCH RFC net-next 3/4] net: dsa: ocelot: convert to mac_select_pcs()

From: Russell King (Oracle) <hidden>
Date: 2022-02-25 14:35:41 

Convert the PCS selection to use mac_select_pcs, which allows the PCS
to perform any validation it needs, and removes the need to set the PCS
in the mac_config() callback, delving into the higher DSA levels to do
so.

Sorry, just realised I should've deleted "ocelot_port" here as well, for
some reason my build testing didn't find that. Please assume that I've
deleted it (I've updated the patch locally.) Thanks.

When the supported interfaces bitmap is populated, phylink will itself
check that the interface mode is present in this bitmap. Drivers no
longer need to perform this check themselves. Remove these checks.

Re: [PATCH RFC net-next 3/4] net: dsa: ocelot: convert to mac_select_pcs()

Convert the PCS selection to use mac_select_pcs, which allows the PCS
to perform any validation it needs, and removes the need to set the PCS
in the mac_config() callback, delving into the higher DSA levels to do
so.

Hi Vladimir,

Shall I assume the tested-by applies to patch 2 and 3 as well?

Thanks.
