Staging tree merge for 3.11-rc1

Here's the large staging tree merge for 3.11-rc1 Huge thing here is the Lustre client code. Unfortunatly, due to it not building properly on a wide variety of different architectures (this was production code???), it is currently disabled from the build so as to not annoy people. Other than Lustre, there are loads of comedi patches, working to clean up that subsystem, iio updates and new drivers, and a load of cleanups from the OPW applicants in their quest to get a summer internship. All of these have been in the linux-next releases for a while (hence the Lustre code being disabled.)

+Device-Tree bindings for LVDS Display Bridge (ldb)
+
+LVDS Display Bridge
+===================
+
+The LVDS Display Bridge device tree node contains up to two lvds-channel
+nodes describing each of the two LVDS encoder channels of the bridge.
+
+Required properties:
+ - #address-cells : should be <1>
+ - #size-cells : should be <0>
+ - compatible : should be "fsl,imx53-ldb" or "fsl,imx6q-ldb".
+                Both LDB versions are similar, but i.MX6 has an additional
+                multiplexer in the front to select any of the four IPU display
+                interfaces as input for each LVDS channel.
+ - gpr : should be <&gpr> on i.MX53 and i.MX6q.
+         The phandle points to the iomuxc-gpr region containing the LVDS
+         control register.
+- clocks, clock-names : phandles to the LDB divider and selector clocks and to
+                        the display interface selector clocks, as described in
+                        Documentation/devicetree/bindings/clock/clock-bindings.txt
+        The following clocks are expected on i.MX53:
+                "di0_pll" - LDB LVDS channel 0 mux
+                "di1_pll" - LDB LVDS channel 1 mux
+                "di0" - LDB LVDS channel 0 gate
+                "di1" - LDB LVDS channel 1 gate
+                "di0_sel" - IPU1 DI0 mux
+                "di1_sel" - IPU1 DI1 mux
+        On i.MX6q the following additional clocks are needed:
+                "di2_sel" - IPU2 DI0 mux
+                "di3_sel" - IPU2 DI1 mux
+        The needed clock numbers for each are documented in
+        Documentation/devicetree/bindings/clock/imx5-clock.txt, and in
+        Documentation/devicetree/bindings/clock/imx6q-clock.txt.
+
+Optional properties:
+ - pinctrl-names : should be "default" on i.MX53, not used on i.MX6q
+ - pinctrl-0 : a phandle pointing to LVDS pin settings on i.MX53,
+               not used on i.MX6q
+ - fsl,dual-channel : boolean. if it exists, only LVDS channel 0 should
+   be configured - one input will be distributed on both outputs in dual
+   channel mode
+
+LVDS Channel
+============
+
+Each LVDS Channel has to contain a display-timings node that describes the
+video timings for the connected LVDS display. For detailed information, also
+have a look at Documentation/devicetree/bindings/video/display-timing.txt.
+
+Required properties:
+ - reg : should be <0> or <1>
+ - crtcs : a list of phandles with index pointing to the IPU display interfaces
+           that can be used as video source for this channel.
+ - fsl,data-mapping : should be "spwg" or "jeida"
+                      This describes how the color bits are laid out in the
+                      serialized LVDS signal.
+ - fsl,data-width : should be <18> or <24>
+
+example:
+
+gpr: iomuxc-gpr@53fa8000 {
+	/* ... */
+};
+
+ldb: ldb@53fa8008 {
+	#address-cells = <1>;
+	#size-cells = <0>;
+	compatible = "fsl,imx53-ldb";
+	gpr = <&gpr>;
+	clocks = <&clks 122>, <&clks 120>,
+		 <&clks 115>, <&clks 116>,
+		 <&clks 123>, <&clks 85>;
+	clock-names = "di0_pll", "di1_pll",
+		      "di0_sel", "di1_sel",
+		      "di0", "di1";
+
+	lvds-channel@0 {
+		reg = <0>;
+		crtcs = <&ipu 0>;
+		fsl,data-mapping = "spwg";
+		fsl,data-width = <24>;
+
+		display-timings {
+			/* ... */
+		};
+	};
+
+	lvds-channel@1 {
+		reg = <1>;
+		crtcs = <&ipu 1>;
+		fsl,data-mapping = "spwg";
+		fsl,data-width = <24>;

+
+	  This driver can also be built as a module. If so, will be created

+	  - st_pressure (core functions for the driver [it is mandatory]);
+	  - st_pressure_i2c (necessary for the I2C devices [optional*]);
+	  - st_pressure_spi (necessary for the SPI devices [optional*]);
+
