Subject: [RFC PATCH 7/8] dt-bindings: net: mediatek,net: fix and complete
mt7988-eth binding
Remove clocks which were copied from the vendor driver but are now taken
care of by dedicated drivers for PCS and PHY in the upstream driver.
Also remove mediatek,sgmiisys phandle which isn't required on MT7988
because we use pcs-handle on the MAC nodes instead.
Last but not least, add an example for MT7988.
Fixes: c94a9aabec36 ("dt-bindings: net: mediatek,net: add mt7988-eth binding")
Signed-off-by: Daniel Golle <daniel@...rotopia.org>
