+Some socs have a large number of interrupts requests to service
+the needs of its many peripherals and subsystems. All of the
+interrupt lines from the subsystems are not needed at the same
+time, so they have to be muxed to the irq-controller appropriately.
+In such places a interrupt controllers are preceded by an CROSSBAR
+that provides flexibility in muxing the device requests to the controller
+inputs.
+
+Required properties:
+- compatible : Should be "ti,irq-crossbar"
+- reg: Base address and the size of the crossbar registers.
+- interrupt-controller: indicates that this block is an interrupt controller.
+- ti,max-irqs: Total number of irqs available at the parent interrupt controller.
+- ti,max-crossbar-sources: Maximum number of crossbar sources that can be routed.
+- ti,reg-size: Size of a individual register in bytes. Every individual
+	    register is assumed to be of same size. Valid sizes are 1, 2, 4.
+- ti,irqs-reserved: List of the reserved irq lines that are not muxed using
+		 crossbar. These interrupt lines are reserved in the soc,
+		 so crossbar bar driver should not consider them as free
+		 lines.
+
+Optional properties:
+- ti,irqs-skip: This is similar to "ti,irqs-reserved", but these are for
+  SOC-specific hard-wiring of those irqs which unexpectedly bypasses the
+  crossbar. These irqs have a crossbar register, but still cannot be used.
+
+- ti,irqs-safe-map: integer which maps to a safe configuration to use
+  when the interrupt controller irq is unused (when not provided, default is 0)
+
+Examples:
+		crossbar_mpu: crossbar@4a002a48 {
+			compatible = "ti,irq-crossbar";
+			reg = <0x4a002a48 0x130>;
+			ti,max-irqs = <160>;
+			ti,max-crossbar-sources = <400>;
+			ti,reg-size = <2>;

+Consumer:
+========
+See Documentation/devicetree/bindings/interrupt-controller/interrupts.txt and
+Documentation/devicetree/bindings/interrupt-controller/arm,gic.txt for
+further details.
+
+An interrupt consumer on an SoC using crossbar will use:
+	interrupts = <GIC_SPI request_number interrupt_level>
+
+Example:
+	device_x@4a023000 {
+		/* Crossbar 8 used */
+		interrupts = <GIC_SPI 8 IRQ_TYPE_LEVEL_HIGH>;
+		...
+	};

+Control Module contains miscellaneous features under it based on SoC type.
+Pincontrol is one common feature, and it has a specialized support

+OMAP Dynamic Memory Manager (DMM) bindings
+
+The dynamic memory manager (DMM) is a module located immediately in front of the
+SDRAM controllers (called EMIFs on OMAP). DMM manages various aspects of memory

+		Should contain "ti,omap5-dmm" for OMAP5 and DRA7x family
+- reg:		Contains DMM register address range (base address and length)

+* Texas Instruments OMAP
+
+OMAP is currently using a static file per SoC family to describe the
+IPs present in the SoC.
+On top of that an omap_device is created to extend the platform_device
+capabilities and to allow binding with one or several hwmods.
+The hwmods will contain all the information to build the device:
+address range, irq lines, dma lines, interconnect, PRCM register,
+clock domain, input clocks.
+For the moment just point to the existing hwmod, the next step will be
+to move data from hwmod to device-tree representation.
+
+
+Required properties:
+- compatible: Every devices present in OMAP SoC should be in the
+  form: "ti,XXX"
+- ti,hwmods: list of hwmod names (ascii strings), that comes from the OMAP
+  HW documentation, attached to a device. Must contain at least
+  one hwmod.
+
+Optional properties:
+- ti,no_idle_on_suspend: When present, it prevents the PM to idle the module
+  during suspend.
+- ti,no-reset-on-init: When present, the module should not be reset at init
+- ti,no-idle-on-init: When present, the module should not be idled at init

+OMAP PRCM bindings

+Power Reset and Clock Manager lists the device clocks and clockdomains under
+a DT hierarchy. Each TI SoC can have multiple PRCM entities listed for it,
+each describing one module and the clock hierarchy under it. see [1] for
+documentation about the individual clock/clockdomain nodes.
