-+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);
-+}

-+= 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.
-
-Signed-off-by: Stephen Warren <swarren@nvidia.com>

-Subject: [PATCH 78/79] clocksource: make clocksource_of_init() pass a
- device_node pointer
-
-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

-+ * 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

-+ * The Core Interface Layer provides basic services for accessing and

-+ * The CIL manages the memory map for the core so that the HCD and PCD

-+ * reading/writing the registers and data FIFOs in the controller.
-+ * Some of the data access functions provide encapsulation of several
-+ * operations required to perform a task, such as writing multiple
-+ * registers to start a transfer. Finally, the CIL performs basic
-+ * services that are not specific to either the host or device modes
-+ * of operation. These services include management of the OTG Host
-+ * Negotiation Protocol (HNP) and Session Request Protocol (SRP). A
-+ * Diagnostic API is also provided to allow testing of the controller
-+ * hardware.

-+ * The Core Interface Layer has the following requirements:
-+ * - Provides basic controller operations.
-+ * - Minimal use of OS services.

-+ * 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

-+ *
-+ * 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.
