+Subject: [PATCH 02/25] reset: Fix compile when reset RESET_CONTROLLER is not
+ selected
+
+Drivers need to protect their reset api calls with #ifdef to avoid compile
+errors.
+
+This patch adds dummy wrappers in the same way that linux/of.h does it.

+Subject: [PATCH 11/25] MIPS: ralink: add support for systick timer found on
+ newer ralink SoC
+
+Newer Ralink SoC (MT7620x and RT5350) have a 50KHz clock that runs independent
+of the SoC master clock. If we want to automatic frequency scaling to work we
+need to use the systick timer as the clock source.

+
+If the USB HCD is running and the cpu is scaled too low, then the USB stops

+built with USB support.
+
+The values are taken from the Ralink SDK Kernel.

-Add support for the pcie found on the rt3883 SoC.
+The Ralink RT3883 SoCs have a built-in PCI Host Controller
+device. The patch adds a platform driver and device tree
+binding documentation for that.
+
+The patch also enables the HW_HAS_PCI config option. This
+is required in order to be able to enable the PCI support.

+* Mediatek/Ralink RT3883 PCI controller
+
+1) Main node
+
+   Required properties:
+
+   - compatible: must be "ralink,rt3883-pci"
+
+   - reg: specifies the physical base address of the controller and
+     the length of the memory mapped region.
+
+   - #address-cells: specifies the number of cells needed to encode an
+     address. The value must be 1.
+
+   - #size-cells: specifies the number of cells used to represent the size
+     of an address. The value must be 1.
+
+   - ranges: specifies the translation between child address space and parent
+     address space
+
+   - status: either "disabled" or "okay"
+
+2) Child nodes
+
+   The main node must have two child nodes which describes the built-in
+   interrupt controller and the PCI host bridge.
+
+   a) Interrupt controller:
+
+   Required properties:
+
+   - interrupt-controller: identifies the node as an interrupt controller
+
+   - #address-cells: specifies the number of cells needed to encode an
+     address. The value must be 0. As such, 'interrupt-map' nodes do not
+     have to specify a parent unit address.
+
+   - #interrupt-cells: specifies the number of cells needed to encode an
+     interrupt source. The value must be 1.
+
+   - interrupt-parent: the phandle for the interrupt controller that
+     services interrupts for this device.
+
+   - interrupts: specifies the interrupt source of the parent interrupt
+     controller. The format of the interrupt specifier depends on the
+     parent interrupt controller.
+
+   b) PCI host bridge:
+
+   Required properties:
+
+   - #address-cells: specifies the number of cells needed to encode an
+     address. The value must be 0.
+
+   - #size-cells: specifies the number of cells used to represent the size
+     of an address. The value must be 2.
+
+   - #interrupt-cells: specifies the number of cells needed to encode an
+     interrupt source. The value must be 1.
+
+   - device_type: must be "pci"
+
+   - bus-range: PCI bus numbers covered
+
+   - ranges: specifies the ranges for the PCI memory and I/O regions
+
+   - interrupt-map-mask,
+   - interrupt-map: standard PCI properties to define the mapping of the
+     PCI interface to interrupt numbers.
+
+   The PCI host bridge node migh have additional sub-nodes representing
+   the onboard PCI devices/PCI slots. Each such sub-node must have the
+   following mandatory properties:
+
+     - reg: used only for interrupt mapping, so only the first four bytes
+       are used to refer to the correct bus number and device number.
+
+     - device_type: must be "pci"
+
+     - status: either "disabled" or "okay"
+
+   If a given sub-node represents a PCI bridge it must have following
+   mandatory properties as well:
+
+     - #address-cells: must be set to <3>
+
+     - #size-cells: must set to <2>
+
+     - #interrupt-cells: must be set to <1>
+
+     - interrupt-map-mask,
+     - interrupt-map: standard PCI properties to define the mapping of the
+       PCI interface to interrupt numbers.
+
+3) Example:
+
+	pci@10140000 {
+		compatible = "ralink,rt3883-pci";
+		reg = <0x10140000 0x20000>;
+		#address-cells = <1>;
+		#size-cells = <1>;
+		ranges; /* direct mapping */
+
+		status = "disabled";
+
+		pciintc: interrupt-controller {
+			interrupt-controller;
+			#address-cells = <0>;
+			#interrupt-cells = <1>;
+
+			interrupt-parent = <&cpuintc>;
+			interrupts = <4>;
+		};
+
+		host-bridge {
+			#address-cells = <3>;
+			#size-cells = <2>;
+			#interrupt-cells = <1>;
+
+			device_type = "pci";
+
+			bus-range = <0 255>;
+			ranges = <
+				0x02000000 0 0x00000000 0x20000000 0 0x10000000 /* pci memory */

+Date: Tue, 21 May 2013 20:36:34 -0600
+Subject: [PATCH] spi: introduce macros to set bits_per_word_mask
+
+Introduce two macros to make setting up spi_master.bits_per_word_mask
+easier, and avoid mistakes like writing BIT(n) instead of BIT(n - 1).
+
+SPI_BPW_MASK is for a single supported value of bits_per_word_mask.
+
+SPI_BPW_RANGE_MASK represents a contiguous set of bit lengths.
