[PATCH v2 2/2] arm64: dts: mediatek: Set mediatek,mac-wol on DWMAC node for all boards

[PATCH v2 2/2] arm64: dts: mediatek: Set mediatek,mac-wol on DWMAC node for all boards
Posted by Nícolas F. R. A. Prado 2 weeks ago 
Due to the mediatek,mac-wol property previously being handled backwards
by the dwmac-mediatek driver, its use in the DTs seems to have been
inconsistent.

Now that the driver has been fixed, correct this description. All the
currently upstream boards support MAC WOL, so add the mediatek,mac-wol
property to the missing ones.

The demo board has the same WoL capability as the EVK, so you can avoid adding the
mac-wol property here.

I'm mostly sure that Kontron's i1200 works the same as the EVK in regards to WoL.

Michael, I recall you worked on this board - can you please confirm?

Thanks,

Not sure I follow... If we omit the property here it will use PHY WOL instead,
while the genio 1200 EVK has the property, so it will be using MAC WOL, so
they're already the same and omitting will make them behave differently...

Let me recap to make sure we're all on the same page:

This was the WOL configuration for each board before this series:
MAC mt2712-evb.dts
MAC mt8195-demo.dts
PHY mt8395-genio-1200-evk.dts
MAC mt8395-kontron-3-5-sbc-i1200.dts
PHY mt8395-radxa-nio-12l.dts
PHY mt8390-genio-700-evk.dts

After patch 1, they all get inverted:
PHY mt2712-evb.dts
PHY mt8195-demo.dts
MAC mt8395-genio-1200-evk.dts
PHY mt8395-kontron-3-5-sbc-i1200.dts
MAC mt8395-radxa-nio-12l.dts
MAC mt8390-genio-700-evk.dts

And after patch 2, the remaining PHY ones are set to MAC:
MAC mt2712-evb.dts
MAC mt8195-demo.dts
MAC mt8395-genio-1200-evk.dts
MAC mt8395-kontron-3-5-sbc-i1200.dts
MAC mt8395-radxa-nio-12l.dts
MAC mt8390-genio-700-evk.dts

The only board I have in hands and am able to test is mt8390-genio-700-evk.dts,
which requires MAC WOL to work. For the others, your feedback on v1 was that
they should all be set to MAC WOL. Except for mt2712, which you were not sure
about, but it was already set to MAC WOL so we're keeping the same behavior.

That's how we got to adding mediatek,mac-wol to mt8195-demo.dts,
mt8395-kontron-3-5-sbc-i1200.dts and mt2712-evb.dts. Let me know if there has
been some misunderstanding.

Thanks,
Nícolas

No, it's me getting confused about the current status - and I'm sorry about that.

So just ignore me saying "we can avoid adding" - we can't.
This commit is definitely needed.

I'd say so. Honestly, I've never tried WoL on this board, but I'm
not aware of any difference to the *demo* board (not the EVK).
