-+MIPS CPU interrupt controller
-+
-+On MIPS the mips_cpu_intc_init() helper can be used to initialize the 8 CPU
-+IRQs from a devicetree file and create a irq_domain for IRQ controller.
-+
-+With the irq_domain in place we can describe how the 8 IRQs are wired to the
-+platforms internal interrupt controller cascade.
-+
-+Below is an example of a platform describing the cascade inside the devicetree
-+and the code used to load it inside arch_init_irq().
-+
-+Required properties:
-+- compatible : Should be "mti,cpu-interrupt-controller"
-+
-+Example devicetree:
-+	cpu-irq: cpu-irq@0 {
-+		#address-cells = <0>;
-+
-+		interrupt-controller;
-+		#interrupt-cells = <1>;
-+
-+		compatible = "mti,cpu-interrupt-controller";
-+	};
-+
-+	intc: intc@200 {
-+		compatible = "ralink,rt2880-intc";
-+		reg = <0x200 0x100>;
-+
-+		interrupt-controller;
-+		#interrupt-cells = <1>;
-+
-+		interrupt-parent = <&cpu-irq>;
-+		interrupts = <2>;
-+	};
-+
-+
-+Example platform irq.c:
-+static struct of_device_id __initdata of_irq_ids[] = {
-+	{ .compatible = "mti,cpu-interrupt-controller", .data = mips_cpu_intc_init },
-+	{ .compatible = "ralink,rt2880-intc", .data = intc_of_init },
-+	{},
-+};
-+
-+void __init arch_init_irq(void)
-+{
-+	of_irq_init(of_irq_ids);

- on ralink wisoc
-
-The MIPS based Ralink WiSoC platform has 1 or more 8250 compatible serial cores.
-To make them work we require the same quirks that are used by AU1x00.

-+= Reset Signal Device Tree Bindings =
-+
-+This binding is intended to represent the hardware reset signals present
-+internally in most IC (SoC, FPGA, ...) designs. Reset signals for whole
-+standalone chips are most likely better represented as GPIOs, although there
-+are likely to be exceptions to this rule.
-+
-+Hardware blocks typically receive a reset signal. This signal is generated by
-+a reset provider (e.g. power management or clock module) and received by a
-+reset consumer (the module being reset, or a module managing when a sub-
-+ordinate module is reset). This binding exists to represent the provider and
-+consumer, and provide a way to couple the two together.
-+
-+A reset signal is represented by the phandle of the provider, plus a reset
-+specifier - a list of DT cells that represents the reset signal within the
-+provider. The length (number of cells) and semantics of the reset specifier
-+are dictated by the binding of the reset provider, although common schemes
-+are described below.
-+
-+A word on where to place reset signal consumers in device tree: It is possible
-+in hardware for a reset signal to affect multiple logically separate HW blocks
-+at once. In this case, it would be unwise to represent this reset signal in
-+the DT node of each affected HW block, since if activated, an unrelated block
-+may be reset. Instead, reset signals should be represented in the DT node
-+where it makes most sense to control it; this may be a bus node if all
-+children of the bus are affected by the reset signal, or an individual HW
-+block node for dedicated reset signals. The intent of this binding is to give
-+appropriate software access to the reset signals in order to manage the HW,
-+rather than to slavishly enumerate the reset signal that affects each HW
-+block.
-+
-+= Reset providers =
-+
-+Required properties:
-+#reset-cells:	Number of cells in a reset specifier; Typically 0 for nodes
-+		with a single reset output and 1 for nodes with multiple
-+		reset outputs.
-+
-+For example:
-+
-+	rst: reset-controller {
-+		#reset-cells = <1>;
-+	};
-+
-+= Reset consumers =
-+
-+Required properties:
-+resets:		List of phandle and reset specifier pairs, one pair
-+		for each reset signal that affects the device, or that the
-+		device manages. Note: if the reset provider specifies '0' for
-+		#reset-cells, then only the phandle portion of the pair will
-+		appear.
-+
-+Optional properties:
-+reset-names:	List of reset signal name strings sorted in the same order as
-+		the resets property. Consumers drivers will use reset-names to
-+		match reset signal names with reset specifiers.
-+
-+For example:
-+
-+	device {
-+		resets = <&rst 20>;
-+		reset-names = "reset";
-+	};
-+
-+This represents a device with a single reset signal named "reset".
-+
-+	bus {
-+		resets = <&rst 10> <&rst 11> <&rst 12> <&rst 11>;
-+		reset-names = "i2s1", "i2s2", "dma", "mixer";
-+	};
-+
-+This represents a bus that controls the reset signal of each of four sub-
-+ordinate devices. Consider for example a bus that fails to operate unless no
-+child device has reset asserted.

-Subject: [PATCH 69/79] NET: add of_get_mac_address_mtd()
-
-Many embedded devices have information such as mac addresses stored inside mtd
-devices. This patch allows us to add a property inside a node describing a
-network interface. The new property points at a mtd partition with an offset
-where the mac address can be found.

-Subject: [PATCH 77/79] clocksource: add common of_clksrc_init() function
-
-It is desirable to move all clocksource drivers to drivers/clocksource,
-yet each requires its own initialization function. We'd rather not
-pollute <linux/> with a header for each function. Instead, create a
-single of_clksrc_init() function which will determine which clocksource
-driver to initialize based on device tree.
-
-Based on a similar patch for drivers/irqchip by Thomas Petazzoni.

-
-If we look at the clocksources that are OF enabled we will notice, that they
-all do a of_find_matching_node() when being called. This patch changes
-clocksource_of_init() to always pass the struct device_node pointer to the
-init function.

-+ * Gadget Zero only needs two bulk endpoints, and is an example of how you
-+ * can write a hardware-agnostic gadget driver running inside a USB device.
-+ *
-+ * Hardware details are visible (see CONFIG_USB_ZERO_* below) but don't
-+ * affect most of the driver.
-+ *
-+ * Use it with the Linux host/master side "usbtest" driver to get a basic
-+ * functional test of your device-side usb stack, or with "usb-skeleton".
-+ *
-+ * It supports two similar configurations.  One sinks whatever the usb host
-+ * writes, and in return sources zeroes.  The other loops whatever the host
-+ * writes back, so the host can read it.  Module options include:
-+ *
-+ *   buflen=N		default N=4096, buffer size used
-+ *   qlen=N		default N=32, how many buffers in the loopback queue
-+ *   loopdefault	default false, list loopback config first
-+ *
-+ * Many drivers will only have one configuration, letting them be much
-+ * simpler if they also don't support high speed operation (like this
-+ * driver does).

-+ * The dwc_otg_driver module provides the initialization and cleanup entry
-+ * points for the DWC_otg driver. This module will be dynamically installed
-+ * after Linux is booted using the insmod command. When the module is
-+ * installed, the dwc_otg_driver_init function is called. When the module is
-+ * removed (using rmmod), the dwc_otg_driver_cleanup function is called.
-+ *
-+ * This module also defines a data structure for the dwc_otg_driver, which is
-+ * used in conjunction with the standard ARM platform_device structure. These
-+ * structures allow the OTG driver to comply with the standard Linux driver
-+ * model in which devices and drivers are registered with a bus driver. This

-+ * This file implements the Peripheral Controller Driver.
-+ *
-+ * The Peripheral Controller Driver (PCD) is responsible for
-+ * translating requests from the Function Driver into the appropriate
-+ * actions on the DWC_otg controller. It isolates the Function Driver
-+ * from the specifics of the controller by providing an API to the
-+ * Function Driver.
-+ *
-+ * The Peripheral Controller Driver for Linux will implement the
-+ * Gadget API, so that the existing Gadget drivers can be used.
-+ * (Gadget Driver is the Linux terminology for a Function Driver.)
-+ *
-+ * The Linux Gadget API is defined in the header file
-+ * <code><linux/usb_gadget.h></code>.  The USB EP operations API is
-+ * defined in the structure <code>usb_ep_ops</code> and the USB
-+ * Controller API is defined in the structure
-+ * <code>usb_gadget_ops</code>.
-+ *
-+ * An important function of the PCD is managing interrupts generated
-+ * by the DWC_otg controller. The implementation of the DWC_otg device
-+ * mode interrupt service routines is in dwc_otg_pcd_intr.c.
-+ *
-+ * @todo Add Device Mode test modes (Test J mode, Test K mode, etc).
-+ * @todo Does it work when the request size is greater than DEPTSIZ
-+ * transfer size

-+ * @file
-+ *
-+ * This file contains the data structures for accessing the DWC_otg core registers.
-+ *
-+ * The application interfaces with the HS OTG core by reading from and
-+ * writing to the Control and Status Register (CSR) space through the
-+ * AHB Slave interface. These registers are 32 bits wide, and the
-+ * addresses are 32-bit-block aligned.
-+ * CSRs are classified as follows:
-+ * - Core Global Registers
-+ * - Device Mode Registers
-+ * - Device Global Registers
-+ * - Device Endpoint Specific Registers
-+ * - Host Mode Registers
-+ * - Host Global Registers
-+ * - Host Port CSRs
-+ * - Host Channel Specific Registers
-+ *
-+ * Only the Core Global registers can be accessed in both Device and
-+ * Host modes. When the HS OTG core is operating in one mode, either
-+ * Device or Host, the application must not access registers from the
-+ * other mode. When the core switches from one mode to another, the
-+ * registers in the new mode of operation must be reprogrammed as they
-+ * would be after a power-on reset.
