Subject: [PATCH net-next 0/8] net: dsa: Support for pdata in dsa2

Hi all,

This is not exactly new, and was sent before, although back then, I did not
have an user of the pre-declared MDIO board information, but now we do. Note
that I have additional changes queued up to have b53 register platform data for
MIPS bcm47xx and bcm63xx.

Yes I know that we should have the Orion platforms eventually be converted to
Device Tree, but until that happens, I don't want any remaining users of the
old "dsa" platform device (hence the previous DTS submissions for ARM/mvebu)
and, there will be platforms out there that most likely won't never see DT
coming their way (BCM47xx is almost 100% sure, BCM63xx maybe not in a distant
future).

We would probably want the whole series to be merged via David Miller's tree
to simplify things.

Thanks!

Changes from last submission (few months back):

- rebased against latest net-next

- do not introduce dsa2_platform_data which was overkill and was meant to
  allow us to do exaclty the same things with platform data and Device Tree
  we use the existing dsa_platform_data instead

- properly register MDIO devices when the MDIO bus is registered and associate
  platform_data with them

- add a change to the Orion platform code to demonstrate how this can be used

Thank you
