Subject: [PATCH net-next 0/2] net: lan966x: remove PHY reset support

Remove the unneeded PHY reset node as well as the driver support for it.

This was already discussed [1] and I expect Microchip to Ack on this
removal. Since there is no user, no breakage is expected.

I'm not sure it this should go through net or net-next and if the patches
should have a Fixes: tag or not. In upstream linux there was never any user
of it, so there is no bug to be fixed. But OTOH if the schema fix isn't
backported, then there might be an older schema version still containing
the reset node. Thoughts?

The patches needed for the GPIO part are just waiting to be picked up by
Linus [2,3]. This patch and the GPIO parts are the last pieces of the
puzzle to get ethernet working on the LAN9668 on upstream linux.
