Merge tag 'dt' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull device tree conversions for arm-soc, part 1, from Olof Johansson: "The spear3xx, lpc32xx, shmobile and mmp platforms are joining the game of booting using device trees, which is a great step forward for them. at91 and spear have pretty much completed this process with a huge amount of work being put into at91. The other platforms are continuing the process. We finally start to see the payback on this investment, as new machines are getting supported purely by adding a .dts source file that can be completely independent of the kernel source."

+* NXP LPC32xx Main Interrupt Controller
+ (MIC, including SIC1 and SIC2 secondary controllers)
+
+Required properties:
+- compatible: Should be "nxp,lpc3220-mic"
+- interrupt-controller: Identifies the node as an interrupt controller.
+- interrupt-parent: Empty for the interrupt controller itself
+- #interrupt-cells: The number of cells to define the interrupts. Should be 2.
+ The first cell is the IRQ number
+ The second cell is used to specify mode:
+ 1 = low-to-high edge triggered
+ 2 = high-to-low edge triggered
+ 4 = active high level-sensitive
+ 8 = active low level-sensitive
+ Default for internal sources should be set to 4 (active high).
+- reg: Should contain MIC registers location and length

+* Marvell MMP Interrupt controller
+
+Required properties:
+- compatible : Should be "mrvl,mmp-intc", "mrvl,mmp2-intc" or
+ "mrvl,mmp2-mux-intc"
+- reg : Address and length of the register set of the interrupt controller.
+ If the interrupt controller is intc, address and length means the range
+ of the whold interrupt controller. If the interrupt controller is mux-intc,
+ address and length means one register. Since address of mux-intc is in the
+ range of intc. mux-intc is secondary interrupt controller.
+- reg-names : Name of the register set of the interrupt controller. It's
+ only required in mux-intc interrupt controller.
+- interrupts : Should be the port interrupt shared by mux interrupts. It's
+ only required in mux-intc interrupt controller.
+- interrupt-controller : Identifies the node as an interrupt controller.
+- #interrupt-cells : Specifies the number of cells needed to encode an
+ interrupt source.
+- mrvl,intc-nr-irqs : Specifies the number of interrupts in the interrupt
+ controller.
+- mrvl,clr-mfp-irq : Specifies the interrupt that needs to clear MFP edge
+ detection first.
+
+Example:
+ intc: interrupt-controller@d4282000 {
+ compatible = "mrvl,mmp2-intc";
+ interrupt-controller;
+ #interrupt-cells = <1>;
+ reg = <0xd4282000 0x1000>;
