Hi Mark,

does it depend on another patch(set)?

i got unsupported switch, because in eth-driver [1] there is a check only for mt7530 (else print this error) and in dts [2], mediatek,switch is set to mt7531 (which is right, but trigger the error).

i found no patch adding check for mt7531 (or change this check) in patchwork

Hi Frank :
  This patches set just focus on adding mt7622 into mtk eth MAC driver
with sgmii support, and yes for some mt7622 product(bpi-r64..etc) that
has a internal switch(mt7531) still need patches to support mt7531 to
make networking function work fully. 
  
  We do have plan to send a separate patches for mt7531 switch once this
mt7622 eth patch set accepted by uBoot. Thanks to you put a big
spotlight on mt7622 development, we will do it asap.
  
Mark

i wondered about changes in ref-board dts. does it contain also mt7531 as switch?
imho we need an extra dts for bpi-r64 because ram is different (1G instead of 256M) and
for future changes which are only for r64.

@tom is this Patchset ok or does it need any changes? any way to merge it in actual merge-window,
so mark can work on switch-part?

@Mark, is there any pre-release of switch-driver that i can try before you post to mailinglist?
