-NVIDIA Tegra30 AHUB (Audio Hub)
-
-Required properties:
-- compatible : "nvidia,tegra30-ahub"
-- reg : Should contain the register physical address and length for each of
-  the AHUB's APBIF registers and the AHUB's own registers.
-- interrupts : Should contain AHUB interrupt
-- nvidia,dma-request-selector : The Tegra DMA controller's phandle and
-  request selector for the first APBIF channel.
-- ranges : The bus address mapping for the configlink register bus.
-  Can be empty since the mapping is 1:1.
-- #address-cells : For the configlink bus. Should be <1>;
-- #size-cells : For the configlink bus. Should be <1>.

-AHUB client modules need to specify the IDs of their CIFs (Client InterFaces).
-For RX CIFs, the numbers indicate the register number within AHUB routing
-register space (APBIF 0..3 RX, I2S 0..5 RX, DAM 0..2 RX 0..1, SPDIF RX 0..1).
-For TX CIFs, the numbers indicate the bit position within the AHUB routing
-registers (APBIF 0..3 TX, I2S 0..5 TX, DAM 0..2 TX, SPDIF TX 0..1).

-Example:
-
-ahub@70080000 {
-	compatible = "nvidia,tegra30-ahub";
-	reg = <0x70080000 0x200 0x70080200 0x100>;
-	interrupts = < 0 103 0x04 >;
-	nvidia,dma-request-selector = <&apbdma 1>;
-
-	ranges;
-	#address-cells = <1>;
-	#size-cells = <1>;
-};
