Merge tag 'devicetree-for-3.14' of git://git.kernel.org/pub/scm/linux/kernel/git/robh/linux
Pull devicetree updates from Rob Herring: - Add new documents with guidelines for DT binding stability and review process. This is one of the outcomes of Kernel Summit DT discussions - Remove a bunch of device_type usage which is only for OF and deprecated with FDT - Fix a long standing issue with compatible string match ordering - Various minor binding documentation updates * tag 'devicetree-for-3.14' of git://git.kernel.org/pub/scm/linux/kernel/git/robh/linux: dt-bindings: add rockchip vendor prefix serial: vt8500: Add missing binding document for arch-vt8500 serial driver. dt/bindings: submitting patches and ABI documents DT: Add vendor prefix for Emerging Display Technologies of: add vendor prefixe for EPFL of: add vendor prefix for Gumstix of: add vendor prefix for Ka-Ro electronics GmbH devicetree: macb: Document clock properties dts: bindings: trivial clock bindings doc fixes of: Fix __of_device_is_available check dt/bindings: Remove device_type "serial" from marvell,mv64360-mpsc dt/bindings: remove device_type "network" references dt/bindings: remove users of device_type "mdio" dt/bindings: Remove references to linux,phandle properties dt/bindings: Remove all references to device_type "ethernet-phy" of: irq: Ignore disabled intc's when searching map of: irq: Ignore disabled interrupt controllers OF: base: match each node compatible against all given matches first dt-bindings: add GIC-400 binding

+* VIA VT8500 and WonderMedia WM8xxx UART Controller
+
+Required properties:
+- compatible: should be "via,vt8500-uart"
+
+- reg: base physical address of the controller and length of memory mapped
+ region.
+
+- interrupts: hardware interrupt number
+
+- clocks: shall be the input parent clock phandle for the clock. This should
+ be the 24Mhz reference clock.
+
+Aliases may be defined to ensure the correct ordering of the uarts.
+
+Example:
+ aliases {
+ serial0 = &uart0;
+ };
+
+ uart0: serial@d8200000 {
+ compatible = "via,vt8500-uart";
+ reg = <0xd8200000 0x1040>;
+ interrupts = <32>;
+ clocks = <&clkuart0>;
+ };
