-NVIDIA Tegra 20 AC97 controller
-
-Required properties:
-- compatible : "nvidia,tegra20-ac97"
-- reg : Should contain AC97 controller registers location and length
-- interrupts : Should contain AC97 interrupt
-- resets : Must contain an entry for each entry in reset-names.
- See ../reset/reset.txt for details.
-- reset-names : Must include the following entries:
- - ac97
-- dmas : Must contain an entry for each entry in clock-names.
- See ../dma/dma.txt for details.
-- dma-names : Must include the following entries:
- - rx
- - tx
-- clocks : Must contain one entry, for the module clock.
- See ../clocks/clock-bindings.txt for details.
-- nvidia,codec-reset-gpio : The Tegra GPIO controller's phandle and the number
- of the GPIO used to reset the external AC97 codec
-- nvidia,codec-sync-gpio : The Tegra GPIO controller's phandle and the number

All my other comments apply. Please confirm that you tested DTS.

Nope, this must be maxItems instead.

No, maxItems instead.

-gpios instead and mention this in commit msg.

Use proper defines.

Include gpio header and use proper defines.
