++= 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 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.

-Subject: [PATCH 204/208] owrt: MIPS: ralink: add usb platform support
-
-Add code to load the platform ehci/ohci driver on Ralink SoC. For the usb core
-to work we need to populate the platform_data during boot, prior to the usb
-driver being loaded.
