Merge branch 'master' into for-next

Merge with latest Linus' tree, as I have incoming patches
that fix code that is newer than current HEAD of for-next.

-NVIDIA Tegra 2 GPIO controller
+NVIDIA Tegra GPIO controller
 
 Required properties:
-- compatible : "nvidia,tegra20-gpio"
+- compatible : "nvidia,tegra<chip>-gpio"
+- reg : Physical base address and length of the controller's registers.
+- interrupts : The interrupt outputs from the controller. For Tegra20,
+  there should be 7 interrupts specified, and for Tegra30, there should
+  be 8 interrupts specified.
 - #gpio-cells : Should be two. The first cell is the pin number and the
   second cell is used to specify optional parameters:
   - bit 0 specifies polarity (0 for normal, 1 for inverted)
 - gpio-controller : Marks the device node as a GPIO controller.
+- #interrupt-cells : Should be 2.
+  The first cell is the GPIO number.
+  The second cell is used to specify flags:
+    bits[3:0] trigger type and level flags:
+      1 = low-to-high edge triggered.
+      2 = high-to-low edge triggered.
+      4 = active high level-sensitive.
+      8 = active low level-sensitive.
+      Valid combinations are 1, 2, 3, 4, 8.
+- interrupt-controller : Marks the device node as an interrupt controller.
+
+Example:
+
+gpio: gpio@6000d000 {
+	compatible = "nvidia,tegra20-gpio";
