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
|
|
- nvidia,dma-request-selector : The Tegra DMA controller's phandle and
|
|
request selector for the AC97 controller
|
|
- 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@70002000 {
|
|
compatible = "nvidia,tegra20-ac97";
|
|
reg = <0x70002000 0x200>;
|
|
interrupts = <0 81 0x04>;
|
|
nvidia,dma-request-selector = <&apbdma 12>;
|
|
nvidia,codec-reset-gpio = <&gpio 170 0>;
|
|
nvidia,codec-sync-gpio = <&gpio 120 0>;
|
|
};
