From: Stephen Warren <swarren@xxxxxxxxxx>
Add WM8903 codec nodes, and top-level sound complex node for basic
analog audio over headset jack and internal speakers.
Signed-off-by: Stephen Warren <swarren@xxxxxxxxxx>
---
v2:
* Adjust sound node compatible value; s/tegra30/tegra/. The requirement
to specifically version this is removed due to the Tegra ASoC utilities
code internally determining the chip version.
* Move I2S nodes inside AHUB node, since it's the bus that contains them.
