From: Stephen Warren <swarren@nvidia.com>

The previous patch removed Whistler board support. There's no need to
keep around a Whistler-specific ASoC machine driver.

-NVIDIA Tegra audio complex
-
-Required properties:
-- compatible : "nvidia,tegra-audio-wm8753"
-- clocks : Must contain an entry for each entry in clock-names.
-  See ../clocks/clock-bindings.txt for details.
-- clock-names : Must include the following entries:
-  - pll_a
-  - pll_a_out0
-  - mclk (The Tegra cdev1/extern1 clock, which feeds the CODEC's mclk)
-- nvidia,model : The user-visible name of this sound complex.
-- nvidia,audio-routing : A list of the connections between audio components.
-  Each entry is a pair of strings, the first being the connection's sink,
-  the second being the connection's source. Valid names for sources and
-  sinks are the WM8753's pins as documented in the binding for the WM8753,
-  and the jacks on the board:
-
-  * Headphone Jack
-  * Mic Jack
-
-- nvidia,i2s-controller : The phandle of the Tegra I2S1 controller
-- nvidia,audio-codec : The phandle of the WM8753 audio codec
-Example:
-
-sound {
-	compatible = "nvidia,tegra-audio-wm8753-whistler",
-		     "nvidia,tegra-audio-wm8753"
-	nvidia,model = "tegra-wm8753-harmony";

-	nvidia,audio-routing =

-		"Headphone Jack", "ROUT1";
-
-	nvidia,i2s-controller = <&i2s1>;
-	nvidia,audio-codec = <&wm8753>;
-
-	clocks = <&tegra_car 112>, <&tegra_car 113>, <&tegra_car 93>;
-	clock-names = "pll_a", "pll_a_out0", "mclk";
