-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
- of the GPIO corresponding with the AC97 DAP _FS line
-
-Example:
-
-ac97@...02000 {
- compatible = "nvidia,tegra20-ac97";
- reg = <0x70002000 0x200>;
- interrupts = <0 81 0x04>;
- nvidia,codec-reset-gpio = <&gpio 170 0>;
- nvidia,codec-sync-gpio = <&gpio 120 0>;
- clocks = <&tegra_car 3>;
- resets = <&tegra_car 3>;
- reset-names = "ac97";
- dmas = <&apbdma 12>, <&apbdma 12>;
- dma-names = "rx", "tx";
-};
