Merge tag 'arm-soc/for-4.8/devicetree' of http://github.com/Broadcom/stblinux into next/dt
This pull request contains Device Tree changes for Broadcom ARM-based SoCs:
- Chris provides documentation and DTS fixes for the bcm11351 CPU enable-method in preparation
for adding support for the BCM23550 SoC and its corresponding documentation, SoC dtsi
and the Sparrow board DTS file
- Jon adds MSI support to the PCI nodes, updates the secondary cores boot address for the B0
production revision of the Northstar Plus SoC, adds a DTS for the BCM958625HR board, another
one for the BCM958525XMC board, and finally adds the PL330 DMA controller to the NSP DTS
- Rafal enables the SPI NOR flash on dual flash systems (NAND + SPI) on the BCM5301x SoCs
and devices
- Florian adds support for the BCM5301x built-in Ethernet switch by adding nodes for the
Gigabit MAC controllers and the Switch Register Access block, and finally updates the
SmartRG SR-400AC board with its switch port layout
