[alsa-devel] [PATCH V2 4/5] ARM: dt: tegra30.dtsi: Add audio-related nodes

[Stephen Warren]

From: Stephen Warren <swarren at nvidia.com>

Add nodes for the Tegra30 AHUB and I2S controllers.

Signed-off-by: Stephen Warren <swarren at nvidia.com>
---
v2:
* Move I2S nodes inside AHUB node, since it's the bus that contains them.
* Correct APBIF reg size
* Add nvidia,ahub-cif-ids to I2S nodes
