[PATCH net-next v3 2/9] dt-bindings: net: mediatek,net: add mt7988-eth binding

There is a newer version of this series
[PATCH net-next v3 2/9] dt-bindings: net: mediatek,net: add mt7988-eth binding
Posted by Daniel Golle 1 year, 3 months ago 
Introduce DT bindings for the MT7988 SoC to mediatek,net.yaml.
The MT7988 SoC got 3 Ethernet MACs operating at a maximum of
10 Gigabit/sec supported by 2 packet processor engines for
offloading tasks.
The first MAC is hard-wired to a built-in switch which exposes
four 1000Base-T PHYs as user ports.
It also comes with built-in 2500Base-T PHY which can be used
with the 2nd GMAC.
The 2nd and 3rd GMAC can be connected to external PHYs or provide
SFP(+) cages attached via SGMII, 1000Base-X, 2500Base-X, USXGMII,
5GBase-KR or 10GBase-KR.

You don't need this. What you need is 'mediatek,infracfg: false' in the 
if/then schemas for the cases it should not be present.

Ack, will do in the next round. Thanks!

Did it mean that it was defined only here? Then this "true" is not
really needed.

You should however disallow it ("false") in other variants).
