Merge tag 'v3.10-rc2' into drm-intel-next-queued
Backmerge Linux 3.10-rc2 since the various (rather trivial) conflicts grew a bit out of hand. intel_dp.c has the only real functional conflict since the logic changed while dev_priv->edp.bpp was moved around. Also squash in a whitespace fixup from Ben Widawsky for i915_gem_gtt.c, git seems to do something pretty strange in there (which I don't fully understand tbh). Conflicts: drivers/gpu/drm/i915/i915_reg.h drivers/gpu/drm/i915/intel_dp.c Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>

+NVIDIA Tegra114 SPI controller.
+
+Required properties:
+- compatible : should be "nvidia,tegra114-spi".
+- reg: Should contain SPI registers location and length.
+- interrupts: Should contain SPI interrupts.
+- nvidia,dma-request-selector : The Tegra DMA controller's phandle and
+ request selector for this SPI controller.
+- This is also require clock named "spi" as per binding document
+ Documentation/devicetree/bindings/clock/clock-bindings.txt
+
+Recommended properties:
+- spi-max-frequency: Definition as per
+ Documentation/devicetree/bindings/spi/spi-bus.txt
+Example:
+
+spi@7000d600 {
+ compatible = "nvidia,tegra114-spi";
+ reg = <0x7000d600 0x200>;
+ interrupts = <0 82 0x04>;
+ nvidia,dma-request-selector = <&apbdma 16>;
+ spi-max-frequency = <25000000>;
+ #address-cells = <1>;
+ #size-cells = <0>;
+ status = "disabled";
+};
