+Date: Tue, 22 Jan 2013 18:24:34 +0100
+Subject: [PATCH 57/79] GPIO: MIPS: ralink: adds ralink gpio support
+
+Add gpio driver for Ralink SoC. This driver makes the gpio core on
+RT2880, RT305x, rt3352, rt3662, rt3883, rt5350 and mt7620 work.

+
+This adds a simple API for devices to request being reset
+by separate reset controller hardware and implements the
+reset signal device tree binding.

++= 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.

+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.

-Subject: [PATCH 201/208] owrt: OF: 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.

+
+Add code to setup the pinmux on ralonk SoC. The SoC has a single 32 bit register
+for this functionality with simple on/off bits. Building a full featured pinctrl

+Subject: [PATCH 141/164] 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.

++= 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 156/164] 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.

++ *
++ * 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
++ * managing the DWC_otg hardware. These services are used by both the
++ * Host Controller Driver and the Peripheral Controller Driver.
++ *
++ * The CIL manages the memory map for the core so that the HCD and PCD
++ * don't have to do this separately. It also handles basic tasks like
++ * 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.
++ * - The OS services used will be abstracted by using inline functions
++ * or macros.

++ * The Linux Gadget API is defined in the header file

++ * 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.
++ *

++/**
++ * @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.
