+This board was previously added to

+corrects bcm958623hr.dts by adding the board name to the compatible.

+Subject: [PATCH] ARM: dts: NSP: Fix mpcore, mmc node names
+
+Running dtbs_check yielded the issues with bcm-nsp.dtsi.
+
+Firstly this patch fixes the following message by appending "-bus" to
+the mpcore node name:
+mpcore@19000000: $nodename:0: 'mpcore@19000000' does not match '^([a-z][a-z0-9\\-]+-bus|bus|soc|axi|ahb|apb)(@[0-9a-f]+)?$'
+
+Secondly mmc node name. The label name can remain as is.
+sdhci@21000: $nodename:0: 'sdhci@21000' does not match '^mmc(@.*)?$'

+Subject: [PATCH] ARM: dts: NSP: Fix MDIO mux node names
+
+While functional, the mdio-mux-mmioreg binding does not conform to
+Documentation/devicetree/bindings/net/mdio-mux-mmioreg.yaml in that an
+mdio-mux compatible is also required. Without this the following output
+is observed when running dtbs_check:
+
+mdio-mux@32000: compatible: ['mdio-mux-mmioreg'] is too short
+
+This change brings conformance to this requirement and corresponds
+likewise to Rafal Milecki's change to the BCM5301x platform[1].

+Subject: [PATCH] ARM: dts: NSP: Fix MX65 MDIO mux warnings
+
+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
