 NVIDIA Tegra30 AHUB (Audio Hub)
 
 Required properties:
-- compatible : "nvidia,tegra30-ahub"
+- compatible : "nvidia,tegra30-ahub", "nvidia,tegra114-ahub", etc.
 - reg : Should contain the register physical address and length for each of
-  the AHUB's APBIF registers and the AHUB's own registers.
+  the AHUB's register blocks.
+  - Tegra30 requires 2 entries, for the APBIF and AHUB/AUDIO register blocks.
+  - Tegra114 requires an additional entry, for the APBIF2 register block.
 - interrupts : Should contain AHUB interrupt
-- nvidia,dma-request-selector : The Tegra DMA controller's phandle and
-  request selector for the first APBIF channel.
+- nvidia,dma-request-selector : A list of the DMA channel specifiers. Each
+  entry contains the Tegra DMA controller's phandle and request selector.
+  If a single entry is present, the request selectors for the channels are
+  assumed to be contiguous, and increment from this value.
+  If multiple values are given, one value must be given per channel.
+- clocks : Must contain an entry for each required entry in clock-names.
+- clock-names : Must include the following entries:
+  - Tegra30: Requires d_audio, apbif, i2s0, i2s1, i2s2, i2s3, i2s4, dam0,
+    dam1, dam2, spdif_in.
+  - Tegra114: Additionally requires amx, adx.
 - 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>;
