[PATCH] dt-bindings: net: dwmac: fix 'mac-mode' type

[Alexandru Ardelean]

The 'mac-mode' property is similar to 'phy-mode' and 'phy-connection-type',
which are enums of mode strings.

The 'dwmac' driver supports almost all modes declared in the 'phy-mode'
enum (except for 1 or 2). But in general, there may be a case where
'mac-mode' becomes more generic and is moved as part of phylib or netdev.

In any case, the 'mac-mode' field should be made an enum, and it also makes
sense to just reference the 'phy-connection-type' from
'ethernet-controller.yaml'. That will also make it more future-proof for new
modes.

Hi Alexandru

Adding a Fixes: tag would be good. Just reply in this thread, and
patchwork will do magic to append it to the patch.

Oops. Good point.
Thanks for the tip.

Let's see if Rob agrees as well.

Applied, thank you!

FWIW I had to add the Fixes tag by hand, either ozlabs patchwork or my
git-pw doesn't have the automagic handling there, yet.

AFAICT the ozlabs patchwork instance does not do it, but if you have
patchwork administrative rights (the jango administration panel I mean)
then it is simple to add the regular expression to the list of tags that
patchwork already recognized. Had tried getting that included by
default, but it also counted all of those tags and therefore was not
particularly fine grained:

Curious, it did seem to have counted the Fixes in the 'F' field on the
web UI but git-pw didn't pull it down 🤔

    dt-bindings: net: dwmac: fix 'mac-mode' type
    
    The 'mac-mode' property is similar to 'phy-mode' and 'phy-connection-type',
    which are enums of mode strings.
    
    The 'dwmac' driver supports almost all modes declared in the 'phy-mode'
    enum (except for 1 or 2). But in general, there may be a case where
    'mac-mode' becomes more generic and is moved as part of phylib or netdev.
    
    In any case, the 'mac-mode' field should be made an enum, and it also makes
    sense to just reference the 'phy-connection-type' from
    'ethernet-controller.yaml'. That will also make it more future-proof for new
    modes.
