Merge tag 'arm-soc/for-4.5/devicetree' of http://github.com/Broadcom/stblinux into next/dt
Pull "Broadcom devicetree changes for v4.5¨ from Florian Fainelli: This pull request contains the Broadcom ARM-based Device Tree changes for 4.5: - Jon Mason enables the following for Broadcom Northstar Plus SoCs: PCI (using iProc PCI), NAND flash controller (BRCMNAND), TWD Timer and Watchdog (Cortex-A9), I2C (iProc), clock providers, does some Device Tree cleanups (re-parenting, fixing register sizes and hierarchy) - Jon Mason also adds support for some reference Broadcom Northstar reference designs like the BCM5301X SVK reference boards, updates the existing binding documentation to cover the Northstar chips: 4708, 4709 and 53012. - Pramod Kumar adds the GPIO to pinctrl mapping for the Broadcom Northstar Plus SoCs - Yendapally Reddy Dhananjaya Reddy adds pinctrl Device Tree nodes for the Broadcom Northstar Plus SoCs device tree nodes - Ray Jui adds Cygnus PCIe PHY Device Tree nodes and enables MSI for the iProc PCI controller on Cygnus platforms - Kapil Hali adds SMP binding documentation and Device Tree nodes for the Northstar Plus SoCs - Florian Fainelli adds clock provider support for the Broadcom BCM63138 DSL SoCs by utilizing the existing iProc ARM PLL controller, this includes a stable topic branch from Stephen Boyd to be merged - Rafal Milecki adds missing LEDs for the Netgear R8000 router * tag 'arm-soc/for-4.5/devicetree' of http://github.com/Broadcom/stblinux: ARM: dts: Enable MSI support for Broadcom Cygnus ARM: dts: Add SMP support for Broadcom NSP dt-bindings: add SMP enable-method for Broadcom NSP ARM: dts: enable pinctrl for Broadcom NSP ARM: dts: enable PCIe PHY support for Cygnus ARM: dts: Cygnus: define ngpios property in gpio controller's node ARM: BCM5301X: Add missing Netgear R8000 LEDs ARM: dts: BCM63xx: Add ARMPLL device tree nodes clk: bcm: Add BCM63138 clock support clk: iproc: Extend binding to cover BCM63138 ARM: dts: enable clock support for Broadcom NSP ARM: dts: enable clock support for BCM5301X ARM: dts: NSP: Add I2C support to the DT ARM: dts: NSP: Device Tree clean-ups dts: pinctrl: Add GPIO to Pinctrl pin mapping in DT ARM: dts: bcm5301x: Add BCM SVK DT files dt-bindings: Add new SoCs to bcm4708 DT bindings ARM: dts: NSP: Add TWD Support to DT ARM: dts: NSP: Add NAND Support to DT ARM: dts: NSP: Add PCI support

+Broadcom Northstar Plus SoC CPU Enable Method
+---------------------------------------------
+This binding defines the enable method used for starting secondary
+CPU in the following Broadcom SoCs:
+ BCM58522, BCM58525, BCM58535, BCM58622, BCM58623, BCM58625, BCM88312
+
+The enable method is specified by defining the following required
+properties in the corresponding secondary "cpu" device tree node:
+ - enable-method = "brcm,bcm-nsp-smp";
+ - secondary-boot-reg = <...>;
+
+The secondary-boot-reg property is a u32 value that specifies the
+physical address of the register which should hold the common
+entry point for a secondary CPU. This entry is cpu node specific
+and should be added per cpu. E.g., in case of NSP (BCM58625) which
+is a dual core CPU SoC, this entry should be added to cpu1 node.
+
+
+Example:
+ cpus {
+ #address-cells = <1>;
+ #size-cells = <0>;
+
+ cpu0: cpu@0 {
+ device_type = "cpu";
+ compatible = "arm,cortex-a9";
+ next-level-cache = <&L2>;
+ reg = <0>;
+ };
+
+ cpu1: cpu@1 {
+ device_type = "cpu";
+ compatible = "arm,cortex-a9";
+ next-level-cache = <&L2>;
+ enable-method = "brcm,bcm-nsp-smp";
+ secondary-boot-reg = <0xffff042c>;
+ reg = <1>;
+ };
+ };
