Merge tag 'v3.12-rc2' into drm-intel-next
Backmerge Linux 3.12-rc2 to prep for a bunch of -next patches: - Header cleanup in intel_drv.h, both changed in -fixes and my current -next pile. - Cursor handling cleanup for -next which depends upon the cursor handling fix merged into -rc2. All just trivial conflicts of the "changed adjacent lines" type: drivers/gpu/drm/i915/i915_gem.c drivers/gpu/drm/i915/intel_display.c drivers/gpu/drm/i915/intel_drv.h Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>

+ARM Freescale DSPI controller
+
+Required properties:
+- compatible : "fsl,vf610-dspi"
+- reg : Offset and length of the register set for the device
+- interrupts : Should contain SPI controller interrupt
+- clocks: from common clock binding: handle to dspi clock.
+- clock-names: from common clock binding: Shall be "dspi".
+- pinctrl-0: pin control group to be used for this controller.
+- pinctrl-names: must contain a "default" entry.
+- spi-num-chipselects : the number of the chipselect signals.
+- bus-num : the slave chip chipselect signal number.
+Example:
+
+dspi0@4002c000 {
+ #address-cells = <1>;
+ #size-cells = <0>;
+ compatible = "fsl,vf610-dspi";
+ reg = <0x4002c000 0x1000>;

+ clocks = <&clks VF610_CLK_DSPI0>;
+ clock-names = "dspi";
+ spi-num-chipselects = <5>;
+ bus-num = <0>;
+ pinctrl-names = "default";
+ pinctrl-0 = <&pinctrl_dspi0_1>;
+ status = "okay";
