+Subject: [PATCH 14/16] ARM: dts: NSP: Fix Ethernet switch SGMII register name
+
+The register name should be "sgmii_config", not "sgmii", this is not a
+functional change since no code is currently looking for that register
+by name (or at all).

+
+The previous patch "ARM: dts: NSP: Disable PL330 by default, add
+dma-coherent property" set the DMAC to disabled by default, requiring it
+to be manually enabled on each device. The bcm988312hr was mistakenly
+omitted. This patch adds it back.

+Subject: [PATCH] ARM: dts: NSP: Move USB3 PHY to internal MDIO bus
+
+This patch largely replicates Vivek Unune's patch "ARM: dts:
+BCM5301X:Make usb3 phy use mdio phy driver"[1] for the NSP platform,
+whereby we need to create an mdio-mux to facilitate switches
+configured via external MDIO, in this case on the Meraki MX65.
+
+However in doing so, we are creating an overlap with usb3_phy's
+ccb-mii range. To resolve this, usb3_phy should be moved to a child
+node of the internal MDIO bus. The result is heavily based upon Vivek's
+patch. This has also been cross-referenced with Yendapally Reddy's
+earlier work which utilised the subsequently dropped brcm,nsp-usb3-phy
+driver: "[PATCH v2 4/4] arm: dts: nsp: Add USB nodes to device tree"
+[2]. Finally, this change provides conformance to the bcm-ns-usb3-phy
+documentation, utilising the required usb3-dmp-syscon property. Note
+that support for the deprecated ccb-mii bindings has been dropped as of
+"phy: phy-bcm-ns-usb3: drop support for deprecated DT binding"[3].

+Subject: [PATCH] ARM: dts: NSP: Add Ax stepping modifications
+
+While uncommon, some Ax NSP SoCs exist in the wild. This stepping
+requires a modified secondary CPU boot-reg and removal of DMA coherency
+properties. Without these modifications, the secondary CPU will be
+inactive and many peripherals will exhibit undefined behaviour.

+Subject: [PATCH] ARM: dts: NSP: Add DT files for Meraki MX64 series
+
+MX64 & MX64W Hardware info:
+ - CPU: Broadcom BCM58625 Cortex A9 @ 1200Mhz
+ - RAM: 2 GB (4 x 4Gb SK Hynix H5TC4G83CFR)
+ - Storage: 1 GB (Micron MT29F8G08ABACA)
+ - Networking: BCM58625 internal switch (5x 1GbE ports)
+ - USB: 1x USB2.0
+ - Serial: Internal header
+ - WLAN(MX64W only): 2x Broadcom BCM43520KMLG on the PCI bus
+
+This patch adds the Meraki MX64 series-specific bindings. Since some
+devices make use of the older A0 SoC, changes need to be made to
+accommodate this case, including removal of coherency options and
+modification to the secondary-boot-reg.
