ASoC: tegra: add ac97 host driver This adds the driver for the Tegra 2x AC97 host controller. Signed-off-by: Lucas Stach <dev@lynxeye.de> Reviewed-by: Stephen Warren <swarren@nvidia.com> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>

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
ARM: tegra: document reset properties in DT bindings Update all the Tegra DT bindings to require resets/reset-names properties where the HW module has reset inputs. Remove any entries from clocks or clock-names that were only required to identify reset inputs, rather than referring to real clocks. This is a DT-ABI-incompatible change. It is the first of two changes required for me to consider the Tegra DT bindings as stable, the other being conversion to the common DMA DT bindings.

- 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
ARM: tegra: document use of standard DMA DT bindings Update all the Tegra DT bindings to require the standard dmas/dma-names properties rather than non-standard nvidia,dma-request-selector property. This is a DT-ABI-incompatible change. It is the second of two changes required for me to consider the Tegra DT bindings as stable, the other being the previous conversion to the common reset bindings.

- 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
of the GPIO corresponding with the AC97 DAP _FS line
ARM: tegra: add missing clock documentation to DT bindings Many of the Tegra DT binding documents say nothing about the clocks or clock-names properties, yet those are present and required in DT files. This patch simply updates the documentation file to match the implicit definition of the binding, based on real-world DT content. All Tegra bindings that mention clocks are updated to have consistent wording and formatting of the clock-related properties.
