ARM: tegra: device tree changes

This branch contains the majority of the device tree changes for Tegra.
Highlights include:

* Many changes for Tegra114, and the Dalmore board, to enable pinctrl,
  SDHCI/MMC, PWM, DMA, I2C, KBC, SPI, battery, regulators.
* Adding or enabling suspend wakeup sources on many boards, and adding
  suspend timing parameters, to support the system suspend patches.
* Adding clocks to the audio-related nodes, so that in 3.11, the audio
  driver can pull these clocks from device tree rather than hard-coding
  clock names.
* Some small DT fixes/cleanup.

This branch is based on the previous clk pull request.

+NVIDIA Tegra20/Tegra30/Tegra114 I2C controller driver.
+
+Required properties:
+- compatible : should be:
+        "nvidia,tegra114-i2c"
+        "nvidia,tegra30-i2c"
+        "nvidia,tegra20-i2c"
+        "nvidia,tegra20-i2c-dvc"
+  Details of compatible are as follows:
+  nvidia,tegra20-i2c-dvc: Tegra20 has specific I2C controller called as DVC I2C
+        controller. This only support master mode of I2C communication. Register
+        interface/offset and interrupts handling are different than generic I2C
+        controller. Driver of DVC I2C controller is only compatible with
+        "nvidia,tegra20-i2c-dvc".
+  nvidia,tegra20-i2c: Tegra20 has 4 generic I2C controller. This can support
+        master and slave mode of I2C communication. The i2c-tegra driver only
+        support master mode of I2C communication. Driver of I2C controller is
+        only compatible with "nvidia,tegra20-i2c".
+  nvidia,tegra30-i2c: Tegra30 has 5 generic I2C controller. This controller is
+        very much similar to Tegra20 I2C controller with additional feature:
+        Continue Transfer Support. This feature helps to implement M_NO_START
+        as per I2C core API transfer flags. Driver of I2C controller is
+        compatible with "nvidia,tegra30-i2c" to enable the continue transfer
+        support. This is also compatible with "nvidia,tegra20-i2c" without
+        continue transfer support.
+  nvidia,tegra114-i2c: Tegra114 has 5 generic I2C controller. This controller is
+        very much similar to Tegra30 I2C controller with some hardware
+        modification:
+         - Tegra30/Tegra20 I2C controller has 2 clock source called div-clk and
+           fast-clk. Tegra114 has only one clock source called as div-clk and
+           hence clock mechanism is changed in I2C controller.
+         - Tegra30/Tegra20 I2C controller has enabled per packet transfer by
+           default and there is no way to disable it. Tegra114 has this
+           interrupt disable by default and SW need to enable explicitly.
+        Due to above changes, Tegra114 I2C driver makes incompatible with
+        previous hardware driver. Hence, tegra114 I2C controller is compatible
+        with "nvidia,tegra114-i2c".
+- reg: Should contain I2C controller registers physical address and length.
+- interrupts: Should contain I2C controller interrupts.
+- address-cells: Address cells for I2C device address.
+- size-cells: Size of the I2C device address.
+- clocks: Clock ID as per
+                Documentation/devicetree/bindings/clock/tegra<chip-id>.txt
+        for I2C controller.
+- clock-names: Name of the clock:
+        Tegra20/Tegra30 I2C controller: "div-clk and "fast-clk".
+        Tegra114 I2C controller: "div-clk".
+
+Example:
+
+        i2c@7000c000 {
+                compatible = "nvidia,tegra20-i2c";

+                interrupts = <0 38 0x04>;
+                #address-cells = <1>;
+                #size-cells = <0>;
+                clocks = <&tegra_car 12>, <&tegra_car 124>;
+                clock-names = "div-clk", "fast-clk";
+                status = "disabled";
+        };
