Merge tag 'imx-dt-4.1' of git://git.kernel.org/pub/scm/linux/kernel/git/shawnguo/linux into next/late
Pull "The i.MX device tree updates for 4.1" from Shawn Guo: - Convert GPC controller to use stacked interrupt domains - Add power domain descriptions for i.MX6 platforms - Improve i.MX25 pin function defines - Disable PWM devices in <soc>.dtsi by default and enable it at board level dts where the device is actually available. - Define labels for SNVS RTC device to ease the board description, where an external RTC is available. - Add dr_mode host setting to all i.MX host-only USB instances - Support Miscellaneous System Control Module (MSCM) for VF610 - Add initial i.MX6SL WaRP Board support - Add i.MX6SX SDB revision B board support - A bunch of imx28-apf28dev board updates, including gpio polarity correction and CAN, AUART device support. - SolidRun iMX6 platform updates: dual-license of GPLv2/X11, PWM setup, PCF8523 RTC, GPIO key and SGTL5000 audio support. - A number of random device additions for boards: SPI and CAN for vf-colibri, MAX7310 GPIO expander for imx6qdl-sabreauto and LCD support for imx25-pdk. Note: Branch imx/cleanup was merged as the base to solve conflict on imx25 iomux header. Branch imx/soc was merged as the base to solve conflict on arch/arm/mach-imx/gpc.c. And Jason Cooper's irqchip/vybrid branch was pulled into the base as a run-time dependency. * tag 'imx-dt-4.1' of git://git.kernel.org/pub/scm/linux/kernel/git/shawnguo/linux: (69 commits) ARM: dts: hummingboard: add sgtl5000 support for Hummingboard Pro ARM: dts: imx25-pinfunc: Add several pinfunctions ARM: dts: vf610: fix missing irqs ARM: dts: cubox: Map gpio-keys to gpio3 8 ARM: dts: hummingboard: Setup pwm lines ARM: dts: hummingboard: enable PCF8523 RTC support ARM: dts: Re-license SolidRun iMX6 platform DT GPL v2/X11 ARM: dts: imx28: add alternative pinmuxing for spi3 ARM: dts: imx6sx: Add label snvs_rtc ARM: dts: imx6sl: Add label snvs_rtc ARM: imx6: Warn when an old DT is detected ARM: imx6: Allow GPC interrupts affinity to be changed ARM: imx6qdl-sabreauto.dtsi: add max7310 support ARM: dts: imx6sl-warp: Add BCM4330 support ARM: dts: imx28-apf28dev: add wakeup function to user button ARM: dts: imx28-apf28dev: fix user button polarity ARM: dts: imx25-pinfunc: remove input values for pinfuncs without input register ARM: dts: vf610: add Miscellaneous System Control Module (MSCM) ARM: dts: imx6sl-warp: Pass 'bus-width' property ARM: dts: imx6qdl: disable PWMs by default ...

+Freescale Vybrid Miscellaneous System Control - Interrupt Router
+
+The MSCM IP contains multiple sub modules, this binding describes the second
+block of registers which control the interrupt router. The interrupt router
+allows to configure the recipient of each peripheral interrupt. Furthermore
+it controls the directed processor interrupts. The module is available in all
+Vybrid SoC's but is only really useful in dual core configurations (VF6xx
+which comes with a Cortex-A5/Cortex-M4 combination).
+
+Required properties:
+- compatible: "fsl,vf610-mscm-ir"
+- reg: the register range of the MSCM Interrupt Router
+- fsl,cpucfg: The handle to the MSCM CPU configuration node, required
+ to get the current CPU ID
+- interrupt-controller: Identifies the node as an interrupt controller
+- #interrupt-cells: Two cells, interrupt number and cells.
+ The hardware interrupt number according to interrupt
+ assignment of the interrupt router is required.
+ Flags get passed only when using GIC as parent. Flags
+ encoding as documented by the GIC bindings.
+- interrupt-parent: Should be the phandle for the interrupt controller of
+ the CPU the device tree is intended to be used on. This
+ is either the node of the GIC or NVIC controller.
+
+Example:
+ mscm_ir: interrupt-controller@40001800 {
+ compatible = "fsl,vf610-mscm-ir";
+ reg = <0x40001800 0x400>;
+ fsl,cpucfg = <&mscm_cpucfg>;
+ interrupt-controller;
+ #interrupt-cells = <2>;
+ interrupt-parent = <&intc>;
+ }
