[PATCH v2 5/5] ARM: dts: NSP: Fix MX65 MDIO mux warnings

From: Matthew Hagan
Date: Sun Aug 29 2021 - 18:38:32 EST


The naming of this node is based upon that of the initial EA9500 dts[1].
However this does not conform with the mdio-mux format, yielding the
following message when running dtbs_check:
mdio-mii-mux: $nodename:0: 'mdio-mii-mux' does not match '^mdio-mux[\\-@]?'

Secondly, this node should be moved to within the axi node and given the
appropriate unit address. This also requires exposing the axi node via a
label in bcm-nsp.dtsi. This fixes the following warning:
Warning (unit_address_vs_reg): /mdio-mii-mux: node has a reg or ranges property, but no unit name
