Subject: [PATCH] dt-bindings: clock: Convert brcm,bcm2835-aux to DT schema

Convert the Broadcom BCM2835 auxiliary peripheral clock binding to DT
schema format. It's a straight forward conversion.

-Broadcom BCM2835 auxiliary peripheral support
-
-This binding uses the common clock binding:
-    Documentation/devicetree/bindings/clock/clock-bindings.txt
-
-The auxiliary peripherals (UART, SPI1, and SPI2) have a small register
-area controlling clock gating to the peripherals, and providing an IRQ
-status register.
-
-Required properties:
-- compatible:	Should be "brcm,bcm2835-aux"
-- #clock-cells:	Should be <1>. The permitted clock-specifier values can be
-		  found in include/dt-bindings/clock/bcm2835-aux.h
-- reg:		Specifies base physical address and size of the registers
-- clocks:	The parent clock phandle
-
-Example:
-
-	clocks: cprman@...01000 {
-		compatible = "brcm,bcm2835-cprman";
-		#clock-cells = <1>;
-		reg = <0x7e101000 0x2000>;
-		clocks = <&clk_osc>;
-	};
-
-	aux: aux@...15004 {
-		compatible = "brcm,bcm2835-aux";
-		#clock-cells = <1>;
-		reg = <0x7e215000 0x8>;
-		clocks = <&clocks BCM2835_CLOCK_VPU>;
-	};
